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.
Human waste may not just be flushed down the toilet anymore. At NASA's request, scientists have figured out how to turn human waste into rocket fuel.
The "Eye of Sauron" isn't just something that appears in The Lord of the Rings movies. Astronomers are now using a cosmic feature with the same namesake to measure precise distances to galaxies that are tens of millions of light-years away.
An invisible, science fiction-like shield has been discovered about 7,200 miles above Earth's surface.
Astronomers have captured a spectacular new image of a colorful gathering of middle-aged stars. Known as NGC 3532, this bright open cluster reveals a spectacular array of stars that shine with blue and red light.
NASA scientists have remastered our view of Europa. They've used a mosaic of color images from NASA's Galileo spacecraft and have used modern image processing techniques in order to create a better image of this icy world.
Asteroids and meteorites can slam into planets, generating immense heat and pressures. Now, scientists have taken a closer look at these impacts and found that they may actually create a form of diamond called lonsdaleite.
