Dark Energy Measured with Record-Breaking Map of 1.2 Million Galaxies
A team of hundreds of physicists and astronomers, including those from Berkeley Lab, have announced results from the largest-ever, three-dimensional map of distant galaxies. The team constructed this map to make one of the most precise measurements yet of the dark energy currently driving the accelerated expansion of the Universe.

Messier 67 Star Cluster Harbors Unusual Number of Exotic Giant Planets --"Was It Once Home to Our Sun?"
An international team of astronomers have found that there are far more planets of the hot Jupiter type than expected in a cluster of stars called Messier 67. This surprising result was obtained using a number of telescopes and instruments,...

Galaxy Cluster Spotted in Early Universe
Astronomers discover a vast collection of young galaxies from the early universe.Astronomers have discovered a collection of young galaxies, stretching more than 489 million by 244 million light-years whose light has taken 12 billion years to reach Earth, one of the most massive structures known at that distance - See more at: http://www.skyandtelescope.com/astronomy-news/galaxy-cluster-spotted-in-early-universe/?

Fermi Helps Link Cosmic Neutrino to Blazar Blast
Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Now astronomers using data from NASA's Fermi Gamma-ray Space Telescope and other space- and ground-based observatories have shown that a record-breaking neutrino seen around the same time likely was born in the same event.

'Cannibalism' between stars: New research shows the turbulent past of our sun
Stars are born inside a rotating cloud of interstellar gas and dust, which contracts to stellar densities thanks to its own gravity. Before finding itself on the star, however, most of the cloud lands onto a circumstellar disk forming around the star owing to conservation of angular momentum.The manner in which the material is transported through the disk onto the star, causing the star to grow in mass, has recently become a major research topic in astrophysics.
