A team of European astronomers have discovered a star that by rights shouldn't exist - it's simply not dense enough for current models to explain its formation.
Astronomers at Rice University have released a movie created from still Hubble Telescope images that shows energetic jets of glowing gas being ejected from young stars.
The recent crash of an ISS-bound space freighter has prompted Russia to consider the possibility of ending its permanent human presence in space.
Part of the difficulty of studying asteroids is that they just won't keep still. NASA's current dawn mission to study Vesta, for instance, has taken eight years so far and cost $360 million even before it launched.
The recent disintegration of an ISS-bound space freighter was apparently caused by a malfunctioning gas generator located in the Soyuz carrier rocket's third stage engine.
Astrophysicists have for the first time created a computer model of galaxy formation that results in a spiral galaxy like our own.
Engineers from NASA and the US Department of Energy (DOE) are working on a suitcase-sized nuclear reactor for use on the moon and other planets.
NASA is warning that astronauts may be forced to temporarily abandon the International Space Station (ISS) if a recent space freighter crash prevents Russia from ferrying a fresh crew to the station.
DARPA has released video footage of the Falcon HTV-2 flight earlier this month, which ended unceremoniously after just three minutes when it lost contact with the vehicle. And, guess what, DARPA says the flight was a great success.
Astronauts on the way to Mars could munch on space-grown lettuce, strawberries and carrots, a NASA scienstist says.
Samples brought back from the Itokawa asteroid indicate that it's made up of the remnants of a much larger body.
Berkeley scientists this week discovered a new supernova, closer to Earth than any seen in the last 40 years, and believe they've spotted it within hours of its explosion.
An international team of scientists has discovered a planet made of diamond after first detecting a pulsar using the Parkes and Lovell radio telescopes.
Astronomers have spotted a supermassive black hole in the act of shredding and consuming a star 3.9 billion light years away.
Astronomers have discovered 6 Y dwarfs approximately 40 light-years away from the sun.
A Russian freighter bound for the International Space Station (ISS) disintegrated over Siberia after failing to separate from the third stage of its Soyuz-U carrier rocket.
NASA has concluded that it will cost approximately $8.7 billion to finish construction of the James Webb Space Telescope in time for a 2018 launch.
The first robot member of the International Space Station crew woke up yesterday, six months after its arrival.
Galaxies are running out of the basic building blocks of stars. The universe is forming fewer stars than it used to, and an Australian research team says the reason is a shortage of molecular hydrogen.
Predicting solar flares is going to become increasingly important as the sun hits the most active phase of its 11-year cycle.
