Astronomers at the California Institute of Technology (Caltech), University of Illinois at Urbana-Champaign (UIUC), and University of Hawaii (UH) have discovered 16 close-knit pairs of supermassive black holes in merging galaxies

A group of researchers from the Institute of Space Sciences (IEEC-CSIC) at Universitat Autònoma de Barcelona has discovered, for the first time, a delta Scuti pulsating star that hosts a hot giant transiting planet

The formation is on overdrive. and is located about 12 million light years from Earth. It is the nearest place to us where the conditions are similar to those when the Universe was much younger with lots of stars forming.

Astronomers have uncovered a burgeoning galactic metropolis, the most distant known in the early universe. This ancient collection of galaxies presumably grew into a modern galaxy cluster similar to the massive ones seen today

Researchers at the University of Tennessee, Knoxville, continue to chip away at the mysterious existence of water on the moon -- this time by discovering the origin of lunar water

Crab Nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with a propensity for fireworks -- gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object

The surprising discovery of a supermassive black hole in a small nearby galaxy has given astronomers a tantalizing look at how black holes and galaxies may have grown in the early history of the Universe

Most galaxies in the universe, including our own Milky Way, harbor super-massive black holes varying in mass from about one million to about 10 billion times the size of our sun

A new study from NASA's Chandra X-ray Observatory tells scientists how often the biggest black holes have been active over the last few billion years

Newly released for the holidays, images of Saturn's second largest moon Rhea obtained by NASA's Cassini spacecraft show dramatic views of fractures cutting through craters on the moon's surface, revealing a history of tectonic rumbling
