Ryugu sample reveals asteroid’s inner secrets Samples returned from the Ryugu asteroid by the Hayabusa2 spacecraft are yielding information about materials found just beneath the object’s surface. “The variations in physical properties among the pebbles and sand, which were not expected before spacecraft arrival at the asteroid, reflect the geological history of Ryugu,” scientists wrote […]
Chromosome study hints at early evolution of animals Chromosome changes that took place about 800 million years ago have been examined and used to find genes that may have been present in the earliest moments of animal life. Researchers viewed genomes at the chromosome level to study what they call genome tectonics to find nearly […]
Andromeda may be home to intermediate-mass black hole The nearby Andromeda Galaxy may be harboring an intermediate-mass black hole, a kind of black hole that is yet to be observed. Scientists say evidence points to an intermediate-mass black hole in the globular cluster B023-G078, which is believed to have a stripped nucleus, a condition researchers […]
Stars born from black hole seen in dwarf galaxy A supermassive black hole has been observed helping to create newborn stars in a dwarf galaxy about 34 million light-years from Earth. The stars in Henize 2-10 were seen linked to a huge gas jet coming from the black hole by the Hubble Space Telescope. Live […]
Fossil dating method points to earlier human emergence Humans were likely around about 36,000 years earlier than previously though. Researchers calculated the age of fossils found in Africa using the single crystal argon-argon dating method, analyzing pumice and ash left behind by ancient volcanic eruptions upon which the fossils were resting. Inverse Supernovas responsible for […]
Antiprotons appear to mirror their protons Protons and their antiprotons are mirror images of each other, according to Baryon Antibaryon Symmetry Experiment’s findings. The experiment made more than 24,000 comparisons of oscillations to precisely measure the charge-to-mass ratios. Science News Ancient black holes may be harboring dark secret Black holes that have been around since […]
Trove of species discovered under Antarctic ice Researchers drilling into the ice of Antarctica have found close to 100 different species living in extreme conditions there. The little-known habitat is home to worms, bryozoans and other creatures that thrive in cold and dark conditions. Gizmodo Surface cooling may have carved Pluto’s unique landscape The weird […]
170 new rogue exoplanets detected Around 170 free-floating exoplanets have been detected in the latest findings by a collaboration of astronomers around the globe. The rogue exoplanets were located around 420 light-years from Earth in the Upper Scorpius OB section of the Milky Way. Gizmodo Lifeforms may exist in Venus’s clouds Ammonia may counteract sulfuric […]
Forests were cleared by Neandertals 125K years ago Neandertals cleared a large forest into open land in what is now Germany about 125,000 years ago. Researchers analyzed a pair of lake basins and found hints that the hominids were the first to make significant changes to their landscapes my molding their surroundings. Science News Evidence […]
Massive exoplanet detected in distant binary system Scientists have spotted a huge exoplanet orbiting a pair of stars roughly 325 light-years away that was observed via a direct image. The exoplanet resides in b Centauri, which is hotter than any other known system and is incredibly heavy, weighing in at about 11 times the mass […]
