Astronomers using NASA's Hubble Space Telescope have discovered a new class of planet, completely enveloped by water.
Astronomers, using the Hubble Space Telescope, say they have found a black hole that was once at the core of a now-disintegrated dwarf galaxy.
Astronomers announced the findings of two new circumbinary planets, or worlds that orbit two different stars, during the American Astronomical Society (AAS) meeting in Austin, Texas on Wednesday.
In the distant reaches of the universe, almost 13 billion light-years from Earth, a strange species of galaxy lay hidden. Cloaked in dust and dimmed by the intervening distance, even the Hubble Space Telescope couldn't spy it.
For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull.
In a new paper, researchers from Harvard-Smithsonian Center for Astrophysics and Princeton suggest a new technique for finding aliens: look for their city lights.
Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull.
When a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby.
Older stars may have to slow down their rotations before exploding as supernovae.
Astronomers using NASA's Chandra X-ray Observatory discovered the first pair of supermassive black holes in a spiral galaxy similar to the Milky Way.
