Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and head off problems that could make or break the Mission to Mars. […]

Researchers have discovered that carbonaceous chondrites, a class of meteorites, incorporated hydrated minerals along with organic material from the protoplanetary disk before the formation of planets. […]

One of the most successful and enduring feats of interplanetary exploration, NASA's Opportunity rover mission is at an end after almost 15 years exploring the surface of Mars and helping lay the groundwork for NASA's return to the Red Planet. […]

A recent NASA mission to the dwarf planet Ceres found brilliant, white spots of salts on its surface. New research delved into the factors that influenced the volcanic activity that formed the distinctive spots and that could play a key role in mixing the ingredients for life on other worlds. […]

The Earth's magnetic shield booms like a drum when it is hit by strong impulses, according to new research. […]

NASA's Hubble Space Telescope has uncovered another mysterious dark storm on Neptune and provided a fresh look at a long-lived storm circling around the north polar region on Uranus. […]

A clever use of non-science engineering data from NASA's Mars rover Curiosity has let a team of researchers to measure the density of rock layers in Gale Crater. […]

For the first time ever, astronomers have detected a 1.3 km radius body at the edge of the Solar System. Kilometer sized bodies like the one discovered have been predicted to exist for more than 70 years. These objects acted as an important step in the planet formation process between small initial amalgamations of dust and ice and the planets we see today. […]

Should regulations for environmental protection be valid beyond our solar system? Currently, extra-terrestrial forms of life are only deemed worth protecting if they can be scientifically investigated. But what about the numerous, presumably lifeless planets whose oxygen atmospheres open up the possibility of their settlement by terrestrial life forms? […]

Juna Kollmeier and Sean Raymond kicked off an internet firestorm late last year when they posted a draft of their article about submoons on a preprint server. The online conversation obsessed over the best term to describe such phenomena. But nomenclature was not the point of Kollmeier and Raymond's investigation, who set out to define the physical parameters for moons that would be capable of being stably orbited by other, smaller moons.
