Asymmetric Supernovae: Not All Stellar Explosions Expand Spherically
Stars are balls of glowing gas, with a nearly spherical shape. Accordingly, one would expect that when some stars explode as supernovae at the end of their lives, the resulting colossal fireballs should share this…

Turning Planetary Theory Upside Down: Nine New Exoplanets Found, Some With Retrograde Orbits
The discovery of nine new transiting exoplanets has been announced at the RAS National Astronomy Meeting. When these new results were combined with earlier observations of transiting exoplanets astronomers were surprised to find that six…

Astronomers Find Super-Earth Orbiting Red Dwarf Star; May Have Atmosphere
Astronomers announced that they have discovered a “super-Earth” orbiting a red dwarf star 40 light-years from Earth. They found the distant planet with a small fleet of ground-based telescopes no larger than those many amateur…

First Known Binary Star Is Discovered to Be a Triplet, Quadruplet, Quintuplet, Sextuplet System
In ancient times, people with exceptional vision discovered that one of the brightest stars in the Big Dipper was, in fact, two stars so close together that most people cannot distinguish them. The two stars,…

Planet-Hunting Method Succeeds: Jupiter-like Planet Found Orbiting One Of Smallest Stars
A long-proposed tool for hunting planets has netted its first catch — a Jupiter-like planet orbiting one of the smallest stars known. The technique, called astrometry, was first attempted 50 years ago to search for…

Bonn astronomers simulate life and death in the universe
Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why…
