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.
There may be a new technique to remotely sense exoplanets. For the first time, scientists have measured the passing of a super-Earth in front of a bright, nearby sun-like star using a ground-based telescope.
Astronauts may be getting their espresso fix in space. Scientists have designed a new cup that can defy the low-gravity environment encountered aboard the International Space Station (ISS).
It turns out that DNA can survive a flight through space and even re-entry into Earth's atmosphere-and still pass on genetic information. The findings reveal that DNA is far more resilient that first expected.
