A NASA spacecraft that will return a sample of a near-Earth asteroid named Bennu to Earth in 2023 made the first-ever close-up observations of particle plumes erupting from an asteroid's surface. Bennu also revealed itself to be more rugged than expected, challenging the mission team to alter its flight and sample collection plans, due to the rough terrain.
Research led by the University of Colorado Boulder is revealing the Alice in Wonderland-like physics that govern gravity near the surface of the asteroid Bennu.
VLA image shows the trail of a speeding pulsar pointing directly back at the center of the debris shell from the supernova that created it.
Astronomers have found a runaway pulsar hurtling through space at nearly 2.5 million miles an hour -- so fast it could travel the distance between Earth and the Moon in just 6 minutes.
A UC Riverside-led team used computer models of chemistry in the biosphere and atmosphere to identify two intriguing scenarios in which carbon monoxide readily accumulates in the atmospheres of living planets. The models show that relatively high amounts of carbon monoxide are compatible with life and should not automatically rule out the possibility of life on some planets.
Researchers have detected a radio signal from abundant interstellar dust in MACS0416_Y1, a galaxy 13.2 billion light-years away in the constellation Eridanus. Standard models can't explain this much dust in a galaxy this young, forcing us to rethink the history of star formation. Researchers now think MACS0416_Y1 experienced staggered star formation with two intense starburst periods 300 million and 600 million years after the Big Bang with a quiet phase in between.
Scientists have made observations of a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system. The observations showed that already at this early stage, the cloud contains two objects, a massive 'primary' central star and another 'secondary' forming star, also of high mass.
Herpes viruses reactivate in more than half of crew aboard Space Shuttle and International Space Station missions, according to NASA research published in Frontiers in Microbiology. While only a small proportion develop symptoms, virus reactivation rates increase with spaceflight duration and could present a significant health risk on missions to Mars and beyond.
Hidden in one of the darkest corners of the Orion constellation, this Cosmic Bat is spreading its hazy wings through interstellar space 2,000 light-years away. It is illuminated by the young stars nestled in its core -- despite being shrouded by opaque clouds of dust, their bright rays still illuminate the nebula. Too dim to be discerned by the naked eye, NGC 1788 reveals its soft colors to ESO's Very Large Telescope in this image -- the most detailed to date.
Astrophysicists from the Moscow Institute of Physics and Technology, the Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), and NASA have found an error in the coordinates of active galactic nuclei measured by the Gaia space telescope, and helped correct it.
