One hundred years ago, Einstein predicted the existence of gravitational waves. Today, for the first time, scientists announced that they've actually been detected. Here's what the discovery might mean for our understanding of the universe.
The Kepler Space Telescope is on the hunt for potentially habitable planets, but even the most "Earth-like" planets can look dramatically different than our home. One of them, Kepler-438b, is a case study in just how tough finding a second Earth can be.
The search is on for planets that could harbor life, but many of the candidates that we can see are more like gassy Jupiter than rocky Earth. But those planets may be home to rocky moons that can sustain life themselves
NASA’s Dawn spacecraft already racked up several firsts during its seven-year flight from Earth, and now it's the first-ever spacecraft to orbit a dwarf planet. Scientists are hoping its yearlong stay at Ceres, in the asteroid belt between Mars and Jupiter, will help reveal clues about how Earth got its water.
The British duo Public Service Broadcasting weaves archival tape in their music. Their sophomore album, "The Race for Space," uses clips from the British Film Archive to re-imagine the American and Soviet space race from 1957-1972.
For decades, astronauts have had to drink from plastic bags to keep their water and coffee from floating away. Now NASA is trying out a new "zero-gravity cup" that uses physics to simulate taking a normal sip back on the ground.
Scott and Mark Kelly, like many twins, are taking part in a genetic study to see how environment affects them differently. There's one key twist, though: Scott is commanding the International Space Station, and NASA hopes to see what his yearlong mission might do to his genes.
A recent proposal by Japanese researchers would equip the International Space Station with a laser beam that could blast pieces of orbiting debris away. The reason? Hundreds of thousands of pieces of space junk are circling the Earth at more than 17,000 miles per hour, posing a danger to the ISS and other space projects.
The International Space Station has hundreds of experiments on board, testing everything from how plants grow in space to the effects of microgravity on an astronaut's eyes. But NASA may have scored the ultimate controlled experiment with test subjects Scott and Mark Kelly, twin astronauts.
