Australian researchers who are designing robotic rovers capable of searching for fallen space debris are asking people to share images or videos that they may have captured during last Thursday evening 's skyfall.
While the moon's surface is battered by millions of craters, it also has over 200 holes - steep-walled pits that in some cases might lead to caves that future astronauts could explore and use for shelter, according to new observations from NASA's Lunar Reconnaissance Orbiter spacecraft.
Scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system.
Researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings questions contemporary models of rocky planet formation, including that of Earth.
One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Recent data from the Van Allen Probes - two nearly identical spacecraft that launched in 2012 - address this question.
NASA has issued an Announcement of Opportunity (AO) for proposals about science instruments that could be carried aboard a future mission to Jupiter's moon Europa. Selected instruments could address fundamental questions about the icy moon and the search for life beyond Earth.
Astronomers analyzing a long-lasting blast of high-energy light observed in 2013 report finding features strikingly similar to those expected from an explosion from the universe's earliest stars. If this interpretation is correct, the outburst validates ideas about a recently identified class of gamma-ray burst and serves as a stand-in for what future observatories may see as the last acts of the first stars.
Earlier this week, three planet hunters came together during a live Google Hangout to discuss the discovery boom, consider what state-of-the-art telescopes can - and can't - tell us about exoplanets, as well as ponder the likelihood of finding evidence of life on another planet.
