Researchers are using pollution to help in their search for alien life on other worlds, as described in a study published in The Astrophysical Journal. By observing exoplanet atmospheres, scientists can look for gases like oxygen and methane that only coexist if replenished by life.
NASA's Hubble Space Telescope has allowed astronomers to get a more in-depth look of an outer galaxy's halo of stars than ever before, thanks to new research.
NASA's Fermi Gama-ray Space Telescope recently identified an "exceptional" binary system that not only contains a rapidly spinning neutron star called a pulsar, but also a relatively small yellow star. Interestingly, close examination revealed that this second star serves much like a dance partner for the pulsar, causing it to exhibit some unusual behavior.
Astronomers have recently discovered a transient exoplanet with the longest year ever seen. Circling its star once every 704 days, Kepler-421b easily wins the title of longest orbit among known exoplanets.
Marking the 45th Anniversary of Neil Armstrong's "one small step," the National Security Archive revealed several declassified documents that, among other things, showed that the US had considered militarizing and even blowing up the Moon.
A bright fireball streaking across the sky was spotted by more than 90 witnesses last Thursday night, sparking discussion and speculation as to what it was. The American Meteor Society (AMS) says it was likely a small chunk of space debris, but is waiting for official data to confirm.
NASA's prototype flying robot assistants will be getting the grand tour of the International Space Station (ISS) this weekend, giving the automated helpers ample time to become familiar with their future workplace.
Training astronauts and caving specialists will soon descend into the depths of the Earth in order to train for future space missions, according to the European Space Agency (ESA).
Scientists from the Perimeter Institute are working to prove the multiverse hypothesis, a long-debated and controversial theory that the Universe is actually a giant bubble.
NASA is bringing together marine and atmospheric scientists for a very unusual purpose. The space agency says that it wants to spy on phytoplankton from space.
Ancient soil in a crater dating back some 3.7 billion years suggests that Mars was once much warmer and wetter, and possibly harbored microbial life, according to a new study.
The US Defense Department has chosen to open up bidding for two future launches of satellites essential for national security. This could potentially end what billionaire genius Elon Musk has called a "monopoly" of space-related US defense contracts held by Beoing Co. and Lockheed Martin Corp.
NASA's Mars Curiosity rover lasered a baseball-sized Martian rock just last weekend, and experts got to see the flash of a resulting plasma plume for the first time.
Physicists have used the world's biggest and most powerful laser to zap and crush diamonds, nature's hardest material, the results of which can possibly reveal more about the cores of giant planets, US scientists report.
