Astronomers discover youngest and lowest mass dwarfs
— 22 Apr 2009 15:34 | AstronomyAstronomers have found three brown dwarfs with estimated masses of less than 10 times that of Jupiter, making them among the youngest and lowest mass sub-stellar objects detected in…
Mass-loss leaves close-in exoplanets exposed to the core
— 21 Apr 2009 12:36 | AstronomyAn international team of scientists has found that giant exoplanets orbiting very close to their stars could lose a quarter of their mass during their lifetime. The team found that…
Erratic black hole regulates itself
— 25 Mar 2009 18:00 | AstronomyNew results from NASA's Chandra X-ray Observatory have made a major advance in explaining how a special class of black holes may shut off the high-speed jets they produce. These results…
Calculations show Saturn's rings may be more massive, older
— 23 Sep 2008 11:16 | AstronomySaturn's rings may be more massive than previously thought, and potentially much older, according to calculations that simulate colliding particles in Saturn's rings and their erosion…
Halos of planetary nebulae revealed
— 11 Sep 2008 15:09 | AstronomyStars without enough mass to turn into exploding supernovae end their lives blowing away most of their mass in a non-explosive, but intense stellar wind. Only a hot stellar core remains…

Most black holes might come in only small and large
— 21 Aug 2008 16:07 | AstronomyBlack holes are sometimes huge cosmic beasts, billions of times the mass of our sun, and sometimes petite with just a few times the sun's mass. But do black holes also come in size…
Nanoscale mass sensor can be used to weigh individual atoms and molecules
— 29 Jul 2008 16:09 | PhysicsThere's a new 'gold standard' in the sensitivity of weighing scales. Using the same technology with which they created the world's first fully functional nanotube radio, researchers…
