Astronomers catch binary star explosion inside nebula
The explosion of a binary star inside a planetary nebula has been captured by a team led by UCL (University College London) researchers - an event that has not been witnessed for more than 100 years. View News Article (2008-11-20)

Most stars are born in clusters, some leave 'home'
New modeling studies from Carnegie's Alan Boss demonstrate that most of the stars we see were formed when unstable clusters of newly formed protostars broke up. View News Article (2014-09-25)

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, Alcor and Mizar, were the first binary stars-a pair of stars that orbit each other-ever known. View News Article (2009-12-10)

Rogue supernovas likely flung into space by black hole slingshots
Rogue supernovas that explode all alone in deep space present an astronomical mystery. Where did they come from? How did they get there? The likely answer: a binary black hole slingshot, according to a new study by Ryan Foley, a professor of astronomy and physics at the University of Illinois.  View News Article (2015-08-14)

Distance to nearest galaxy measured
A team of astronomers including Carnegie's Ian Thompson have managed to improve the measurement of the distance to our nearest neighbor galaxy and, in the process, refine an astronomical calculation that helps measure the expansion of the universe.  View News Article (2013-03-07)

Wide binary stars can wreak havoc in planetary systems
An international team of astrophysicists has shown that planetary systems with very distant binary stars are particularly susceptible to violent disruptions, more so than if the systems had two stellar companions with tighter orbits around each other. View News Article (2013-01-08)
