University of Arizona researchers probed Martian meteorites to reconstruct Mars' chaotic history. Their findings suggest that Mars might not have had a global magma ocean.
Despite Mercury's 400 C daytime heat, there is ice at its caps, and now a study shows how that Vulcan scorch probably helps the planet closest to the sun make some of that ice.
A team of researchers has shown a way to determine the origins and nature of quasar light by its polarization. The new approach is analogous to the way cinema glasses produce a 3D image by feeding each eye with the light of a particular polarization: either horizontal or vertical. The authors managed to distinguish between the light coming from different parts of quasars -- their disks and jets -- by discerning its distinct polarizations.
Before the Taqba Dam impounded the Euphrates River in northern Syria in the 1970s, an archaeological site named Abu Hureyra bore witness to the moment ancient nomadic people first settled down and started cultivating crops. A large mound marks the settlement, which now lies under Lake Assad.
Some of the extremely low-density, 'cotton candy like' exoplanets called super-puffs may actually have rings, according to new research published in The Astronomical Journal by Carnegie's Anthony Piro and Caltech's Shreyas Vissapragada.
Mineralogists from Jena and Japan discover a previously unknown phenomenon in soil samples from the asteroid 'Itokawa': the surface of the celestial body is covered with tiny hair-shaped iron crystals. The team provides an explanation of how these were formed, and why asteroids can be unusually low in sulphur compounds, in the current issue of 'Nature Communications'.
Planetary scientists at Curtin University have shed some light on the tumultuous early days of the largely preserved protoplanet Asteroid 4 Vesta, the second largest asteroid in our solar system.
By measuring iron isotopes, researchers from the University of Copenhagen have shown that our planet originally formed much faster than previously thought. This finding provides new insights on both planetary formation and the likelihood of water and life elsewhere in the universe.
MIT engineers devise a decision map to identify the best mission type to deflect an incoming asteroid.
Breakthrough Listen, based at UC Berkeley, announced its second major release of SETI data: a radio survey of the plane of the Milky Way and the galactic center. The public is urged to search the data for signals from intelligent civilizations. A former Berkeley undergraduate initiated the analysis by looking at emissions from 20 nearby stars that could see Earth transiting our sun. The VLA also signed on to capture radio data for SETI.
