This water flow occurred on an ancient asteroid more than one billion years after its formation and was probably triggered by an impact that generated...
Astronomers have imaged planetesimal belts in 74 planetary systems as part of the REsolved ALMA and SMA Observations of Nearby Stars (REASONS) survey.
This...
A new analysis of magmatic iron meteorites challenges traditional theories about why Earth and Mars are depleted in moderately volatile elements.
The Bendego...
Primordial black holes have been theorized for decades and could even be ever-elusive dark matter. Still, no primordial black hole has ever been observed....
The Moon may have been captured during a close encounter between a young Earth and a terrestrial binary (a system of the Moon and another rocky object),...
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted a collision of giant asteroids around Beta Pictoris, the second brightest star...
Dynamically active planetary systems orbit a significant fraction of white dwarf stars. These stars often exhibit surface metals accreted from debris disks....
Dr. Christopher Stark from NASA’s Goddard Space Flight Center and his colleagues present new coronagraphic images from the NIRCam (Near-Infrared Camera)...
A giant collision between the ancient protoplanet Theia and the proto-Earth about 4.5 billion years ago may have formed Earth’s Moon as well as two continent-sized...
The collision between two exoplanets of several to tens of Earth masses occurred at a distance of 2-16 AU (astronomical units) from the young solar-like...
The 5-km-long mounds that dominate the appearance of the larger lobe of Kuiper Belt object (486958) Arrokoth are similar enough to suggest a common origin,...
Scientists have determined a precise lead isotopic age of the andesitic achondrite meteorite Erg Chech 002. Their result, combined with published aluminum-26-magnesium-26...
New research shows that long-lived volcanism, driven by early, energetic collisions on Venus, offers an explanation of its young surface age with stagnant-lid...
In new research, planetary scientists from the University of Maryland and elsewhere analyzed melted meteorites that had been floating around in space since...
Astronomers using NASA’s Infrared Telescope Facility (IRTF) telescope at Mauna Kea Observatory have captured and analyzed visible and near-infrared reflectance...
While the NASA/ESA/CSA James Webb Space Telescope and other space telescopes previously have revealed isolated ingredients of the atmosphere of WASP-39b,...
WD J2147-4035, an 11-billion-year-old white dwarf located 91 light-years away in the constellation of Grus, is accreting debris from orbiting planetesimals,...
New research led by Curtin University geologists suggests that regions of space with dense interstellar clouds may send more high-energy comets crashing...
