Astronomers have discovered that galaxies stop forming stars long before their central supermassive black holes reach their most powerful stage, meaning the black holes can’t be responsible for shutting down star formation.
A new study overturns a longstanding scientific tenet and provides new insights into how convection controls much of what we observe in planets and stars.
NASA is issuing a last call to the nation's youth for entries in a contest to name the agency's next Mars rover.
Theorists have long wondered how massive stars--up to 120 times the mass of the Sun--can form without blowing away the clouds of gas and dust that feed their growth. But the problem turns out to be less mysterious than it once seemed.
Using a NASA radar flying aboard India's Chandrayaan-1 spacecraft, scientists are getting their first look inside the moon's coldest, darkest craters.
Mars today is a world of cold and lonely deserts, apparently without life of any kind, at least on the surface.
Scientists may have solved one of the most longstanding astrophysical mysteries of all times: How massive stars – up to 120 times the mass of our sun – form without blowing away the clouds of gas and dust that feed their growth.
Astronomers have turned to an unexpected place to study the evolution of planets -- dead stars.
Listening to the early universe just got harder. A team led by Alan Kogut of NASA's Goddard Space Flight Center in Greenbelt, Md., today announced the discovery of cosmic radio noise that booms six times louder than expected.
At first, figuring out how pebble-sized rocks organize themselves in evenly-spaced patterns in sand seemed simple and even intuitive.
Using the Very Large Array of radio telescopes, astronomers have identified two protostars located only a few light-years from the galactic center. Their discovery shows that stars can, in fact, form very close to the Milky Way's central black hole.
The International Year of Astronomy 2009 (IYA2009) has been launched by the International Astronomical Union (IAU) and the United Nations Educational, Scientific and Cultural Organization (UNESCO) under the theme, "The Universe, yours to discover".
NASA has released the Spacecraft Crew Survival Integrated Investigation Team report, which includes 30 recommendations to improve spacecraft design and crew safety.
Earth's magnetic field, which shields our planet from particles streaming outward from the Sun, often develops two holes that allow the largest leaks, according to researchers sponsored by NASA and the National Science Foundation.
Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope, astronomers have scrutinised the inner parts of the disc around a supermassive black hole 10 billion light-years away.
