A new analysis of topographic and gravity data from Titan, the largest moon orbiting Saturn,  indicates its icy outer crust is twice as thick as has generally been thought. Is there a vast ocean…

Astronomers find planets in strange places and wonder if they might support life. One such place would be in orbit around a white or brown dwarf. While neither is a star like the sun, both glow and…

Spectacular jets powered by the gravitational energy of a super massive black hole in the core of the elliptical galaxy Hercules A are shown off by the combined imaging power of the Hubble Space…

 Astronomers theorize that an as-yet-unidentified form of matter is responsible for 90 percent of the gravity within galaxies and clusters of galaxies but because it is detected via its gravity…

A monster black hole has been detected.  With 17 billion solar masses, it is significantly heavier than models predict and could be the most massive black hole known to date.   …

NASA's Cassini spacecraft has been orbiting Saturn since 2004 so it has seen a lot - but it recently saw something that has not happened since 1997. Seasonal atmospheric circulation direction changes…

Astronomers have discovered vast comet belts surrounding two nearby planetary systems – GJ 581 and 61 Vir – known to host only Earth-to-Neptune-mass worlds.   Previously, scientists found that…

A jet of X-rays from the supermassive black hole in quasar GB 1428+4217, 12.4 billion light years from Earth, has been detected by NASA's Chandra X-ray Observatory - the most distant X-ray jet…

Quasars are the luminous centers of distant galaxies powered by huge black holes.  Although black holes are noted for pulling material in, most quasars also accelerate some of the material…

NASA's Cassini mission has spotted a second feature shaped like the 1980s video game icon Pac-Man, this time on Saturn's moon Tethys.The pattern appears in thermal data obtained by Cassini's…
