  An unmanned Chinese spacecraft carrying rocks and soil from the Moon returned safely to Earth early Thursday within the first mission in four decades to gather lunar samples, the Xinhua wire service said. The return module of the guided-missile called Chang'e-5 landed in northern China's Inner Mongolia region, Xinhua said, quoting the China National Space Administration. Beijing is looking to catch up with the US and Russia after taking decades to match its rivals' achievements and has poured billions into its military-run space program. The spacecraft, named after a mythical Chinese Moon goddess, landed on the laze on December 1 and commenced its return voyage two days later. While on the Moon it raised the Chinese flag, China's space agency has said. Scientists hope the samples will help them study the Moon's origins, formation, and volcanic activity on its surface. With this mission, China became only the third country to own retrieved samples from the Moon, fo...

  Black sandy dust found during a capsule delivered to Earth by a Japanese guided missile is from the distant asteroid Ryugu, scientists confirmed after opening it on Monday. The discovery comes per week after the Hayabusa-2 probe dropped off its capsule, which entered the atmosphere in an exceeding streak of sunshine before landing within the desert then being transported to Japan. The Japanese space agency (JAXA) released an image of a little deposit of sooty material inside the metal box - a primary glimpse at the results of an unprecedented six-year mission for the uncrewed probe. (JAXA) The dust was found within the capsule's outer shell, agency officials said, with more substantial samples expected to be found once they open the inner container, a fragile task. "JAXA has confirmed that samples derived from the asteroid Ryugu are inside the sample container," the agency said. "We were ready to confirm black, sand-like particles which are believed to be derived f...

 In 2017, NASA space probes detected a large, human-made 'barrier' surrounding Earth. And tests have confirmed that it's actually having sway on space weather far beyond our planet's atmosphere. That means we're not just changing Earth so severely, scientists are calling for an entirely new geological epoch to be named after us - our activities are changing space too. But the great news is that unlike our influence on the world itself, that humungous bubble we created come in space is truly working in our favor. Back in 2012, NASA launched two space probes to figure in tandem with one another as they whizzed through Earth's James Alfred Van Allen Belts at speeds of around 3,200 km/h (2,000 mph).  Our planet is surrounded by two such radiation belts (and a short-lived third one) - the inner belt stretches from around 640 to 9,600 km (400 to six,000 miles) above Earth's surface, while the outer belt occupies an altitude of roughly 13,500 to 58,000 km (8,400 to...

 Invisible structures generated by gravitational interactions within the scheme have created a "space superhighway" network, astronomers have discovered. These channels enable the fast travel of objects through space and will be harnessed for our own space exploration purposes, moreover because of the study of comets and asteroids. By applying analyses to both observational and simulation data, a team of researchers led by Nataša Todorović of Belgrade Astronomical Observatory in Serbia observed that these superhighways encompass a series of connected arches inside these invisible structures, called space manifolds - and every planet generates its own manifolds, together creating what the researchers have called "a true celestial autobahn". This network can transport objects from Jupiter to Neptune in an exceedingly matter of decades, instead of them for much longer timescales, on the order of many thousands to voluminous years, normally found within the scheme. Find...

 WASP-12b is one in every of the more interesting exoplanets we all know of. Orbiting a plant disease star a bit bigger than the Sun 1,410 light-years away, the ultra-black planet is what's called a "hot Jupiter" - a superior planet exoplanet with similar mass and size to Jupiter, but so near the star that it's scorching hot. WASP-12b has never exactly been within the most secure position. With an orbital period of just over each day, the Jovian planet exoplanet is so near its star that a continuing stream of fabric is being siphoned removed from its atmosphere. But its death won't necessarily be by slow stellar slurping. Careful observations have found it is also on a noticeably decaying orbit. And, consistent with new research, that orbit is decaying a touch faster than we initially thought. Rather than the three.25 million years initially estimated, WASP-12b will meet its fiery end in mere 2.9 million years. According to current models of planet formation, tech...

The Sun may be in for a very busy time. According to new predictions, the next maximum in its activity cycles could be one of the strongest we've seen. This is in direct contradiction to the official solar weather forecast from NASA and the NOAA, but if it bears out, it could confirm a theory about solar activity cycles that scientists have been working on for years. "Scientists have struggled to predict both the length and the strength of sunspot cycles because we lack a fundamental understanding of the mechanism that drives the cycle," said solar physicist Scott McIntosh of the US National Center for Atmospheric Research. "If our forecast proves correct, we will have evidence that our framework for understanding the Sun's internal magnetic machine is on the right path." The Sun's activity levels are actually quite variable, and its activity cycles are bound up with its magnetic field. Every 11 years, the Sun's poles swap places; south becomes north...

  Astronomers are using the Dark Energy Camera (DECam) in Chile as a form of the baby monitor, keeping their eye on a neighborhood of nearby space absolutely packed with star nurseries. The Large and little Magellanic Clouds are the sole two dwarf galaxies visible from Earth with the unaided eye, and fortunately enough, they're also home to a number of the foremost active star-forming regions in our Local Group of galaxies. It's not the primary time we've tried to peek in and see what these newborns are up to, but it's the foremost penetrating look yet. The Survey of the Magellanic Stellar History (SMASH) took 50 nights of observation to map in high detail a part 2,400 times greater than the face of the total Moon. The results are breathtaking. Images of the foremost complex regions within the Magellanic Clouds have now provided roughly 4 billion measurements of 360 million objects, which researchers hope to show into a 'home movie' for this celestial family – o...
