NASA's Hubble confirms that galaxies are the ultimate recyclers
— 18 Nov 2011 17:09 | AstronomyNew observations by NASA's Hubble Space Telescope are expanding astronomers' understanding of the ways in which galaxies continuously recycle immense volumes of hydrogen gas and heavy…
Newly merged black hole eagerly shreds stars
— 9 Apr 2011 11:52 | AstronomyA galaxy's core is a busy place, crowded with stars swarming around an enormous black hole. When galaxies collide, it gets even messier as the two black holes spiral toward each other,…
Two dying stars reborn as one
— 9 Apr 2011 11:49 | AstronomyWhite dwarfs are dead stars that pack a Sun's-worth of matter into an Earth-sized ball. Scientists have just discovered an amazing pair of white dwarfs whirling around each other once…
Telescope ferrets out planet-hunting targets
— 9 Apr 2011 11:37 | AstronomyAstronomers have come up with a new way of identifying close, faint stars with NASA's Galaxy Evolution Explorer satellite. The technique should help in the hunt for planets that lie…
Astrophysicist: White dwarfs could be fertile ground for other Earths
— 31 Mar 2011 15:03 | AstronomyPlanet hunters have found hundreds of planets outside the solar system in the last decade, though it is unclear whether even one might be habitable. But it could be that the best place…
The rose-red glow of star formation
— 30 Mar 2011 16:31 | AstronomyThe object dominating this image may resemble a pool of spilled blood, but rather than being associated with death, such regions of ionised hydrogen - known as HII regions - are sites…
A very cool pair of brown dwarfs
— 28 Mar 2011 17:42 | AstronomyBrown dwarfs are essentially failed stars: they lack enough mass for gravity to trigger the nuclear reactions that make stars shine. The newly discovered brown dwarf, identified as…
The drama of starbirth
— 16 Mar 2011 13:12 | AstronomyThe star-forming region NGC 6729 is part of one of the closest stellar nurseries to the Earth and hence one of the best studied. This new image from ESO's Very Large Telescope gives…
Speed demon creates a shock
— 11 Mar 2011 16:10 | AstronomyJust as some drivers obey the speed limit while others treat every road as if it were the Autobahn, some stars move through space faster than others. NASA's Wide-field Infrared Survey…
The most distant mature galaxy cluster
— 9 Mar 2011 20:20 | Astronomy'We have measured the distance to the most distant mature cluster of galaxies ever found,' says the lead author of the study in which the observations from ESO's VLT have been used,…
