70 International Studies Show That a Warming World Increases Risks to Pregnancies

 Climate change poses an on the spot threat to human health, and growing evidence suggests pregnant people are especially at risk of hotter-than-normal summers.

A new analysis of 70 studies from around the world has found higher temperatures during pregnancy are linked to a little increase in preterm births and stillbirths, especially in low- and middle-income countries. 

While the danger appears relatively minimal, scientists are worried it could have a significant impact on public health within the future, especially with global climate change driving more intense and frequent heatwaves. 

Just as young children, the elderly, and people with pre-existing conditions are warned about the risks of maximum heat events, we must always also warn people who are pregnant, they advise.

Carrying a toddler places many new demands on the anatomy, forcing the guts to figure harder, raising internal temperatures, and leaving the body at risk of heat stress, exhaustion, and dehydration.

"Pregnant women merit an area alongside the groups typically considered as a high risk for warmth related conditions," the international team concludes.

This field of research continues to be relatively new, but from what we all know thus far, there's reason to fret both for the mother and therefore the baby.

None of the studies included within the current review are perfect or able to provide a transparent cause or effect. Yet within the larger literature, the pattern is both consistent and concerning.

An observational study published last year supported an assessment of 56 million births within the US also identified a link between rising temperatures and shrinking gestation periods.

"When more and more studies start to gather and coalesce round the same conclusion, we've to listen, especially when there's biological plausibility behind the result," explains obstetrician-gynecologist Nathaniel DeNicola in a very separate 2019 paper on the topic.

Analyzing more studies on the topic than ever before, the present meta-analysis examines how heat sensitivity impacts three outcomes in pregnancy: stillbirths, premature births, and low birth weight. 

The research came from 24 countries, most of which were based in North America, the EU Union, Australia, and New Zealand, although seven came from low- and middle-income countries. 

For each 1°C increase in temperature, researchers found the danger of early birth and stillbirth increased by roughly 5 percent on average. in an exceedingly prolonged wave, the chance of early birth rose by 16 percent.

To put that in perspective, the world average rate of preterm births is about 10 percent, therefore the impact of maximum heat, if there's one, is comparatively small compared to any or all the opposite factors that may influence the outcomes of pregnancy.

The analysis showed low birth weight, for instance, occurred in exactly 3 percent of the infants born during a heatwave, and also the relationship was found much less often.

While only 18 out of 28 studies found a link between birth weight and warmth exposure, 40 out of 47 studies found a link between preterm births and warmth exposure.

"The evidence was strongest and most consistent for heatwaves," the authors write, "although the most important effect sizes were from measures of the cumulative dose of warmth over the entire pregnancy."

This means heat exposure could fine add up throughout pregnancy, although outcomes appear to fluctuate between certain socioeconomic groups.

For instance, while a number of studies suggest low- and middle-income pregnancies are prone to heat exposure for the total nine months, other studies in high-income countries suggest the last weeks of pregnancy are where exposure is most risky.

The different methodologies used and therefore the various different subpopulations examined make it hard to generalize.

What's more, nearly a 3rd of the studies included were deemed of caliber, which implies the conclusions we will draw are limited.

Several studies, for example, found preterm birth rates escalated only if temperatures exceeded 25°C (77°F), and this might explain why other research, which only included temperatures below this threshold, failed to show similar results.

There are with great care many factors to contemplate and control when it involves pregnancy outcomes, including education, access to health care, food security, and availability of air con. Even the sex of the fetus might play a job.

A study in Japan, as an example, found spontaneous abortions were higher among male fetuses after a period of warmth exposure. viewing all 70 studies, the new review found an identical pattern.

What's driving these results is unclear. Some animal studies have found heat exposure during pregnancy can interfere with the synthesis of warmth shock proteins, resulting in fetal cell damage, oxidative stress, or inflammation. Whether this is up in humans remains to be seen.

Further research should be a high priority, especially since the pregnancy risks of heatwaves appear much higher in areas where far fewer protections exist.

"Exposure to high temperatures in agricultural and other outdoor work could occur before the pregnancy is recognized, and, even late in pregnancy, poorer women might work beyond their heat tolerance limits to avoid losing pay," the authors worry.  

From what we all know to date, that's cause for concern, yet up to now, many emergency heat plans around the world, including those within us and Europe, fail to incorporate pregnant people as a vulnerable group.

"Pregnant women as an at-risk group to temperature change are largely ignored," Skye Wheeler, an emergencies researcher for the Women's Rights Division of Human Rights Watch, told BuzzFeed News earlier this year.

That clearly must change.

Simulation Gives a Peek Into The Cosmic 'Dark Age' of Star Formation

 For astronomers, astrophysicists, and cosmologists, the power to identify the primary stars that formed in our Universe has always been just beyond reach. On the one hand, there are the bounds of our current telescopes and observatories, which might only see thus far.

The farthest object ever observed was MACS 1149-JD, a galaxy located 13.2 billion light-years from Earth that was spotted within the Hubble eXtreme Deep Field (XDF) image.

On the opposite, up until about 1 billion years after the large Bang, the Universe was experiencing what cosmologists check with because the "Dark Ages" when the Universe was stuffed with gas clouds that obscured visible and infrared radiation.

Luckily, a team of researchers from Georgia Tech's Center for Relativistic Astrophysics recently conducted simulations that show what the formation of the primary stars appeared like.

The study that describes their findings, published within the Monthly Notices of the Royal Astronomical Society, was led by Gen Chiaki and John Wise – a post-doctoral researcher and professor from the CfRA (respectively).

They were joined by researchers from the Sapienza Università di Roma, the Astronomical Observatory of Rome, the Istituto Nazionale di Astrofisica (INAF), and also the Istituto Nazionale di Fisica Nucleare (INFN).

Based on the life and death cycles of stars, astrophysicists theorize that the primary stars within the Universe were very metal-poor. Having formed about 100 million years after the large bang, these stars formed from a primordial soup of hydrogen gas, helium, and trace amounts of sunshine metals.

These gases would collapse to make stars that were up to 1,000 times more massive than our Sun.

Because of their size, these stars were short-lived and possibly only existed for some million years. in this time, the new and heavier elements in their nuclear furnaces, which were then dispersed once the celebrities collapsed and exploded in supernovae.

As a result, the subsequent generation of stars with heavier elements would contain carbon, resulting in the designation of Carbon-Enhanced Metal-Poor (CEMP) stars.

The composition of those stars, which can be visible to astronomers today, is that the results of the nucleosynthesis (fusion) of heavier elements from the primary generation of stars.

By studying the mechanism behind the formation of those metal-poor stars, scientists can infer what was happening during the cosmic 'Dark Ages' when the primary stars formed. As Wise said in an exceedingly Texas Advanced Computer Center (TACC) press release:

"We can't see the very first generations of stars. Therefore, it is important to really study these living fossils from the first universe, because they need the fingerprints of the primary stars everywhere them through the chemicals that were produced within the supernova from the primary stars."

"That's where our simulations get to play to determine this happening. After you run the simulation, you'll watch a brief movie of it to determine where the metals come from and the way the primary stars and their supernovae actually affect these fossils that live until this day."

Density, temperature, and carbon abundance (top) and the formation cycle of Pop III stars (bottom). (Chiaki, et al.)

For the sake of their simulations, the team relied predominantly on the Georgia Tech PACE cluster. extra time was allocated by the National Science Foundation's (NSF) Extreme Science and Engineering Discovery Environment (XSEDE), the Stampede2 supercomputer at TACC and NSF-funded Frontera system (the fastest academic supercomputer within the world), and also the Comet cluster at the urban center Supercomputer Center (SDSC).

With the huge amounts of processing power and data storage these clusters provided, the team was ready to model the faint supernova of the primary stars within the Universe.

What this revealed was that the metal-poor stars that formed after the primary stars within the Universe became carbon-enhanced through the blending and fallback of bits ejected from the primary supernovae.

Their simulations also showed the gas clouds produced by the primary supernovae were seeding with carbonaceous grains, resulting in the formation of low-mass 'giga-metal-poor' stars that likely still exist today (and may well be studied by future surveys). Said Chiaki of those stars:

"We find that these stars have very low iron content compared to the observed carbon-enhanced stars with billionths of the solar abundance of iron. However, we are able to see the fragmentation of the clouds of gas. this means that the Mass stars form during a low iron abundance regime. Such stars haven't been observed yet. Our study gives us theoretical insight into the formation of first stars."

These investigations are a part of a growing field referred to as "galactic archaeology."

Much like how archaeologists depend upon fossilized remains and artifacts to find out more about societies that disappeared centuries or millennia ago, astronomers rummage around for ancient stars to review so as to find out more about those who have lang syne died.

According to Chiaki, the following step is to vary beyond the carbon features of ancient stars and incorporate other heavier elements into larger simulations. In so doing, galactic archaeologists hope to be told more about the origins and distribution of life in our Universe. Said Chiaki:

"The aim of this study is to grasp the origin of elements, like carbon, oxygen, and calcium. These elements are concentrated through the repetitive matter cycles between the interstellar space and stars. Our bodies and our planet are made from carbon and oxygen, nitrogen, and calcium. Our study is incredibly important to assist understand the origin of those elements that we mortals are fabricated from."

Bizarre molten planet discovered with lava ocean, supersonic winds

 Scientists say they’ve probably recognized a lava world so dramatic that it might boast a thin regional environment of vaporized rock the place it’s closest to its star.

That exoplanet is understood as K2-141b and was initially discovered in 2017. the globe is about half over again as large as Earth however orbits so near its star, which is one class smaller than our personal, that it completes a variety of loops every Earth-day with the identical floor completely inquiring the star. Now, scientists predict these components imply that two-thirds of the ground of K2-141b is totally sunlit — plenty so as that not solely could be a part of the globe coated in a very lava ocean, however, some of that rock could even evaporate away into the environment.

“All rocky planets­, including Earth, started off as molten worlds on the other hand rapidly cooled and solidified,” Nicolas Cowan, a planetary scientist at McGill University in Canada and a co-author on the fresh paper, said in an exceeding statement. “Lava planets give us a rare glimpse at this stage of planetary evolution.”

The scientists behind the latest researchers wished to understand what reasonable environment such a scorching world may have and therefore the way terrestrial instruments would see it. K2-141b was a tempting goal as a result of it's been studied by each the K2 mission of NASA’s Kepler Space Telescope and by the company’s Spitzer Space Telescope. and therefore the environment is very intriguing as the results of scientists consider that NASA’s upcoming James Webb Space Telescope, as a result of launch late subsequent 12 months, will have the power to research the weather of distant planetary atmospheres.

The researchers began with what earlier research has decided about K2-141b up to now — for example, that the planet’s density is this of Earth’s, therefore the crust can be modeled as pure silica as a reasonably simplified illustration. Then, the scientists revealed what the ground may appear to be. that employment took into consideration problems just like the truth that the world is so near its star that greater than half the world’s floor could also be sunlit, maybe as plenty as two-thirds, the researchers calculated.

Such fixed gentle and heat imply that the globe seemingly sports activities a magma ocean tens of miles or kilometers deep, in response to the staff’s calculations. Then, the researchers modeled what an environment right here would seem to be based on three potential predominant elements, all of that are frequent within the crusts of rocky planets.

All three circumstances can help an environment, the scientists calculated, with wind speeds above 1.1 miles (1.75 kilometers) per second, far earlier than the rate of sound correct here on Earth.

At the edges of the environment, the place temperatures drop, the gaseous rock would cool sufficient to fall again to the ground as precipitation, the researchers calculated. If the environment is dominated by silica or silicon monoxide, that precipitation would principally represent the magma ocean, but when the environment is predominantly sodium, the world would look even weirder, with stable sodium oozing again towards the oceans like glaciers here on Earth, the researchers wrote.

But all this modeling wasn’t simply to test what a really weird world might appear to be; that's science, in spite of everything. The researchers wished to test their fashions with the current and predicted observing capacities of enormous area telescopes. Here, the scientists are upbeat: they name K2-141b “an especially good target for atmospheric observations.”

And the researchers even have an answer to maneuver their time prior to the James Webb Space Telescope launches, the scientists stated within the assertion: they’ve acquired Spitzer Space Telescope observations that should assist pin down the temperatures of the planet’s day and evening sides, clarifying how the fashions could match actuality.

The analysis is described in an exceedingly paper revealed Nov. three within the journal the Monthly Notices of the Royal Astronomical Society.

Clinical Trial Finds Substantial Antidepressant Effects From Psilocybin-Assisted Therapy

 When psilocybin - the hallucinogenic compound in magic mushrooms - is employed during supportive psychotherapy, there appear to be rapid, substantial, and enduring antidepressant effects, per a replacement trial. 

The randomized study is tiny and there was no traditional control group, but lead researcher Alan Davis from Johns Hopkins University says he and his team are "really excited about the results."

"We found a statistically significant and extremely large effect," Davis said during a recent podcast.

Among 24 volunteers with major major affective disorder, researchers found psilocybin-assisted therapy was a minimum of twice as effective as psychotherapy on its own, and over fourfold as effective as available antidepressant drugs.

The drug also doesn't require taking a pill every single day, nor does it include nearly as many side effects as antidepressants or ketamine. but occasional mild to moderate headaches and some emotional moments, volunteers within the study tolerated psilocybin quite well and there have been no serious dangers.

The research included two therapy sessions on the drug with 8 hours of prep and a pair of hours of follow-up with a therapist. During the sessions, a pill of psilocybin was administered and participants extended on a couch in a very living room-like space with headphones on for musical stimulation and eyeshades on to spur inward reflection.

During the trial, roughly half the volunteers began psilocybin therapy right away, while the opposite half was placed on a 'waiting list' for eight weeks with regular mental state check-ups.

This served as a kind of control group, with the immediate treatment group faring significantly better than those within the delayed group who weren't receiving the other sorts of treatment.

By the purpose of 4 weeks into the trial, 71 percent of the volunteers showed an improvement, with 50 percent come by depressive symptoms.

A month later, over half the group was considered 'in remission', and therefore the average depression score dropped from 23 to eight. 

"The present trial showed that psilocybin administered within the context of supportive psychotherapy (approximately 11 hours) produced large, rapid, and sustained antidepressant effects," the authors conclude.

Up to a year after the trial, patients were still being checked abreast of, and researchers arrange to publish those ends up in the long run.

Even what we have got up to now looks promising. The findings support other recent studies, which suggest psilocybin-assisted therapy can produce significant and lasting antidepressant effects in precisely one or two sessions.

One prior clinical test found a high-dose and a low-dose session decreased depression and anxiety in patients with life-threatening cancer. Six months later, 80 percent of the patients were still reaping the advantages. 

Another trial among people who weren't responding to other depression and anxiety treatments found similar benefits with two doses that lasted for up to 3 months.

While it's still not clear how psilocybin improves depressive symptoms, the hallucinogen has been tied to several of the identical neural networks as current antidepressant drugs, although it appears to act in a different way. 

Brain imaging studies on those with treatment-resistant depression suggest psilocybin has the alternative effect of selective serotonin reuptake inhibitors (SSRIs), increasing emotional connection rather than blunting it like SSRIs tend to try and do.

In the current trial, for example, researchers say their volunteers reported mystical, personally meaningful, and insightful experiences that were related to a decrease in depression at 4 weeks.

Major clinical depression impacts over 300 million people worldwide and lots of them don't respond easily to existing styles of treatment. Finding better ways to treat this mental disease could bring relief to such a lot of.

Twice last year, the United States' Food and Drug Advisory (FDA) designated psilocybin a "breakthrough therapy" within the hopes it might speed up research, and one in every one of these clinical trials is looking specifically at major depression.

The results are just beginning to are available in, and that we will verify them amongst much larger cohorts and with stronger control groups, but the findings to this point are strong and researchers remain optimistic.

"This is that the first of what's visiting be, over the following number of years, many clinical trials on this subject in depressed populations," says Davis.

"It's looking like within the next four to 6 years that it's possible the FDA might need enough evidence to work out if this treatment is often made available to the general public."

In some areas, the therapy might arrive even sooner. only in the near past, Oregon became the primary state within the US to legalize psilocybin therapy, given its promising results among those with PTSD, addiction, and also depression.

You might be hearing about psychedelic therapy lots more within the future.

World's Biggest Iceberg Is on a Collision Course With a Remote Penguin Sanctuary

 The world's biggest iceberg is on a collision course with an overseas South Atlantic island that's home to thousands of penguins and seals, and will impede their ability to collect food, scientists told AFP Wednesday.

Icebergs naturally break removed from Antarctica into the ocean, but temperature change has accelerated the method - during this case, with potentially devastating consequences for abundant wildlife within the British Overseas Territory of South Georgia.

Shaped sort of a closed hand with a pointing finger, the iceberg called A68a split off in 2017 from Larsen ice on the western peninsula, which has warmed faster than the other a part of Earth's southernmost continent.

At its current rate of travel, it'll take the large cube - which is several times the world of the national capital - 20 to 30 days to run aground into the island's shallow waters.

A68a is 160 kilometres (93 miles) long and 48 kilometres (30 miles) across at its widest point, but the iceberg is a smaller amount than 200 metres deep, which implies it could park dangerously near the island.

"We put the percentages of collision at 50/50," Andrew Fleming from Brits Antarctic Survey told AFP.

Many thousands of King penguins - a species with a bright splash of yellow on their heads - continue to exist the island, alongside Macaroni, Chinstrap and Gentoo penguins.

Seals also populate South Georgia, as do wandering albatrosses, the most important bird species that may fly.

If the iceberg runs aground next to South Georgia, foraging routes might be blocked, hampering the flexibility of penguin parents to feed their young, and thus threatening the survival of seal pups and penguin chicks.

Release of stored carbon

"Global numbers of penguins and seals would visit an oversized margin," Geraint Tarling, also from land Antarctic Survey, told AFP in an interview.

The incoming iceberg would also crush organisms and their seafloor ecosystem, which might need decades or centuries to recover.

Carbon stored by these organisms would be released into the ocean and atmosphere, adding to carbon emissions caused by an act, the researchers said.

As A68a drifted with currents across the Atlantic Ocean, the iceberg did an excellent job of distributing microscopic edibles for the ocean's tiniest creatures, said Tarling.

"Over many years, this iceberg has accumulated plenty of nutrients and mud, and that they are setting out to leach out and fertilise the oceans."

Up to a kilometre thick, icebergs are the solid-ice extension of land-bound glaciers. They naturally break faraway from ice shelves as snow-laden glaciers push toward the ocean.

But warming has increased the frequency of this process, referred to as calving.

"The amount of ice going from the centre of the continent out towards the sides is increasing in speed," Tarling said.

Up to the tip of the 20th century, the Larsen ice had been stable for over 10,000 years. In 1995, however, a large chunk broke off, followed by another in 2002.

This was followed by the breakup of the nearby Wilkins shelf ice in 2008 and 2009, and A68a in 2017.

Hydrofracturing - when water seeps into cracks at the surface, splitting the ice farther down - was almost certainly the most culprit in each case.

Scientists Just Successfully Regenerated Mouse Optic Nerve Cells in The Lab

 Scientists have found a brand new thanks to regenerate damaged nervus opticus cells taken from mice and grown during a dish. This exciting development could lead to potential disease treatments within the future.

Damage to full-grown nerve cells causes irreversible and life-altering consequences because once nerve fibers mature, they lose their ability to regenerate after injury or disease. The new experiments show how activating a part of a nerve cell's regenerative machinery, a protein referred to as protrudin could stimulate nerves within the eye to regrow after injury. 

With more research, the achievement could be a step towards future treatments for glaucoma, a bunch of eye diseases that cause vision loss by damaging the cranial nerve (that links the attention to the brain).

"What we have seen is that the strongest regeneration of any technique we've used before,'' said ophthalmologist Keith Martin from the University of Melbourne in Australia.

"In the past, it seemed impossible we might be able to regenerate the nervus opticus but this research shows the potential of gene therapy to try and do this." 

We have seen similar attempts to revive vision in mice and a few promising results before.

In 2016, scientists were ready to regrow a tiny low fraction of retinal ganglion cells in adult mice by turning on a dormant growth switch and showed these new nerve cells at the rear of the attention reconnected to the proper part of the brain in addition.

And before that, a 2012 study also partially restored 'simple' vision to adult mice after regenerating nerves along the complete length of the optic pathway.

This latest research remains in its early stages and has focused on understanding precisely how protrudin, a scaffolding molecule present in sprouting neurons, works to support cell growth. 

It's always good to possess some options because there is no guarantee that promising leads to mouse studies translate to safe and effective treatments for people.

In this study, scientists stimulated nerve cells of the attention to supply more protrudin, to determine if this could help protect the cells from damage and even repair after injury.

First, in optical nerve cells cultured in a very dish, the researchers showed that ramping up protrudin production stimulated regeneration of nerve cells that had been cut by a laser. Their spindly axons regenerated over longer distances, and in less time than untreated cells. 

(Petrova et al., Nature Communications, 2020)

Above: A regenerating and a non-regenerating axon over 14 hours after laser axotomy. Red arrows at 0 h post-injury show the purpose of injury; white arrows trace the trail of a regenerating axon.

Next, adult mice were administered gene therapy - an injection straight into the attention - carrying instructions for nerve cells to raise protrudin production. As painful as that sounds, this procedure can actually be done safely in people (the injection, that is, not yet the gene therapy).

A few weeks and one-second cranial nerve injury later, these mice had more surviving nerve cells in their retinas than the control group did.

In one final experiment, the scientists used whole retinas from mice removed a fortnight after giving them a protrudin boost, to determine if this treatment could prevent nerve cells from dying in the first place.

The researchers found, three days later, that stimulating protrudin production had been almost "entirely neuroprotective, with these retinas exhibiting no loss of [retinal] neurons," the researchers wrote in their paper. Usually, about 1/2 retinal neurons removed during this way die within a pair of days.

"Our strategy relies on using gene therapy – an approach already in clinical use – to deliver protruding into the attention," said Veselina Petrova, a neuroscience student at the University of Cambridge.

"It's possible our treatment may be further developed as the simplest way of protecting retinal neurons from death, also as stimulating their axons to regrow." 

It's important to notice that we're a protracted way from restoring vision during a person: Regenerating cells in an exceeding dish is great, but we do not know from these experiments if giving a mouse more protrudin would restore its sight. 

One of the following steps is to appear at whether protrudin has an identical protective effect in cultured human retinal cells.

The scientists publishing this work also plan on studying whether the identical technique may well be wont to repair damaged neurons after neural structure injury.

"Treatments identified this fashion often show promise within the injured neural structure," said Petrova. "It's possible that increased or activated protrudin can be wont to boost regeneration within the injured neural structure."

NASA Finally Makes Contact With Voyager 2 After Longest Radio Silence in 30 Years

 There's never been a radio silence quite like this one. After long months with no way of constructing contact with Voyager 2, NASA has finally reestablished communications with the record-setting interstellar spacecraft.

The breakdown in communications – lasting since March, almost eight months and a full pandemic ago – wasn't because of some rogue malfunction, nor any run-in with part weirdness (although there's that too).

In this instance, it absolutely was more a case of routine maintenance. And yet, when you're one in every of the farthest-flying spacecraft in history – leaving Earth and even the whole scheme behind you – nothing much is ever truly routine.

In March, NASA announced that region Station 43 (DSS-43) in Australia, the sole antenna on Earth that may send commands to Voyager 2, required critical upgrades and would want to close up for roughly 11 months for the work to be completed.

During this window, Voyager 2, which is currently over 18.7 billion kilometers (11.6 billion miles) faraway from Earth and getting farther all the time, wouldn't be ready to receive any communications from Earth, although its own broadcasts back to us would still be received by scientists.

As it stands, DSS-43's renovation remains underway and on course to be finalized in February 2021, but enough of the upgrades are installed for preliminary testing to start out.

Last week, mission operators sent their first communications to Voyager 2 since March, issuing a series of commands, and NASA reports that Voyager 2 returned a sign confirming it had received the instructions and executed the commands without issue.

Successful pings between radio antennas and spacecraft aren't usually newsworthy events, but Voyager 2 is such a storied and historic probe (NASA's longest-running space mission in fact), it rightfully gets special attention – especially in situations like this, involving a period of one-way radio silence ciao, it's effectively unprecedented.

According to NASA, DSS-43 hasn't been offline for this long in over 30 years. The old radio aerial that needed replacing – the sole one within the world capable of broadcasting to Voyager 2 – had been in use for over 47 years.

As a part of the refurb, DSS-43 is getting two new antennas, upgraded heating, and cooling equipment, power supply equipment, and other electronics to support the new transmitters. When the work is complete, the upgrades will provide longevity to a cornerstone of a facility that's already legendary.

"What makes this task unique is that we're doing work all levels of the antenna, from the pedestal at ground level all the high to the feedcones at the center of the dish that reaches above the rim," says NASA part Network project manager Brad Arnold.

"This test communication with Voyager 2 definitely tells us that things are on course with the work we're doing."

As for why DSS-43 is that the only dish within the world that may reach Voyager 2, the rationale isn't purely technological. As a result of the probe's flyby of Neptune's moon Triton in 1989, Voyager 2's trajectory steered significantly southward relative to the Solar System's plane of planets, meaning earthbound antennas within the hemisphere don't have any way of reaching it.

For antennas Down Under, though, it's no biggie – unless you get taken offline for nearly a year of critical upgrades. Even then, though, scientists never stopped brooding about Voyager 2, and kept a detailed eye on its vitals.

"We've always been reprehension the spacecraft. We've been doing that daily," Suzanne Dodd, the project manager for the Voyager Interstellar Mission, told CNN.

"We can see the health of it. If it wasn't healthy, we might have known."
