First use of cosmic lens to probe dark energy
— 20 Aug 2010 09:51 | AstronomyAstronomers have devised a new method for measuring perhaps the greatest puzzle of our universe - dark energy. This mysterious force, discovered in 1998, is pushing our universe apart…
Out of whack planetary system offers clues to a disturbed past
— 25 May 2010 12:01 | AstronomyAstronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other. This surprising finding will…
