Austin, TX Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. New work by as...

Austin, TX Astronomers announced today that a mystery object orbiting a star 170 light-years from Earth might have formed from the collision and merger of two protoplanets. The object, k...

Astronomers have come to realize during the past decade that most newborn stars are surrounded by disks of gas and dust, material that both helps the young star to grow, and that might ev...

The Hinode (Japanese for "sunrise") satellite was launched last September to study the sun's magnetic field, and how its explosive energy propagates through the different layers of the so...

Cambridge, MA Astronomers have found the best evidence yet of matter spiraling outward from a young, still-forming star in fountain-like jets. Due to the spiral motion, the jets help the...

Markarian galaxies were discovered and cataloged by the Russian astronomer Biniamin Markarian and his colleagues starting in the early 1960's. These galaxies are unusual in that they appe...

Cambridge, MA A furious rate of star formation discovered in a distant galaxy shows that galaxies in the early universe developed either much faster or in a different way from what astro...

Quasars are galaxies with massive black holes at their cores, around which vast amounts of energy are being radiated. So much light is emitted that the nucleus is much brighter than the r...
