The Dawn spacecraft has snapped its best and most detailed picture yet of Ceres, the largest body in the main asteroid belt.
Where should astronomers look for life on other planets? That's a good question. There are billions and billions of stars in the sky, so narrowing down the search is crucial for success. Now, scientists may have discovered where, and when, infant Earths are most likely to be found.
The intermittent light emitted from pulsars allows scientists to verify Einstein's theory of relativity. However, this theory could be analyzed more effectively if a pulsar with a black hole were found. Now, scientists have announced that this fact isn't the case in two particular instances.
For the first time, astronomers have witnessed the dramatic "blow out" phase of galactic evolution. They've discovered dense gas being blasted out of a compact galaxy at speeds of up to two million miles per hour.
Exoplanets may have burned away their chances to cultivate life.
Scientists have conducted an analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, and have found that the cosmos may be less hostile to space travelers.
Astronomers have managed to detect the faint signal emitted by atomic hydrogen gas in galaxies that are at record-breaking distances from Earth--a staggering three billion light-years.
Astronomers may have found an important new example of a rare type of galaxy. The new finding could help shed light on how galaxies first developed in the early universe.
Whether or not Mars ever possessed or possesses life is still under debate. Now, a new meteorite from the Red Planet may provide some answers. It seems to indicate that Martian life is far more probable than previously thought.
The Herschel Space Observatory has taken a series of stunning images of the galaxy, Andromeda. The new images are the first time that astronomers have seen Andromeda in high-resolution infrared wavelengths.
Scientists have created a cognitive test battery, known as Cognition, to test the impact of long-duration spaceflights on astronauts' brain function.
