Brightest Stars Don't Live Alone: Most Stellar Heavyweights Come in Interacting Pairs, VLT Finds
July 26, 2012 — A study using the European Southern Observatory's Very Large Telescope has shown that most very bright high-mass stars do not live alone. Almost three quarters of them are found to have a close ... > full story -
'Seeds' of Massive Black Holes Found at the Center of the Milky Way Galaxy
July 20, 2012 — Many galaxies contain enormous amounts of molecular gas in small areas near their nuclei. Highly condensed molecular gas is a birthplace of lots of stars. Moreover, it is considered to closely relate ... > full story -
Astronomers Using the Hubble Space Telescope Report the Earliest Spiral Galaxy Ever Seen
July 18, 2012 — Astronomers have discovered the first spiral galaxy in the early universe, billions of years before many other spiral galaxies ... > full story -
Dark Galaxies of the Early Universe Spotted for the First Time
July 11, 2012 — Dark galaxies are small, gas-rich galaxies in the early Universe that are very inefficient at forming stars. They are predicted by theories of galaxy formation and are thought to be the building ... > full story -
Hubble Unmasks Ghost Galaxies
July 10, 2012 — Astronomers are studying some of the smallest and faintest galaxies in our cosmic neighborhood. These galaxies are fossils of the early Universe: They have barely changed for 13 billion years. The ... > full story -
Belching Black Hole Proves a Biggie: First Known 'Middleweight' Black Hole
July 9, 2012 — Astronomers have found the first known "middleweight" black hole. Before it was found, astronomers had good evidence for only supermassive black holes -- ones a million to a billion times the mass of ... > full story -
'Impossible’ Binary Stars Discovered
July 5, 2012 — Astronomers have discovered four pairs of stars that orbit each other, in less than 4 hours. Until now it was thought that such close-in binary stars could not ... > full story -
NuSTAR Space Telescope Opens Its X-Ray Eyes
June 28, 2012 — NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has snapped its first test images of the sizzling high-energy X-ray universe. The observatory, launched June 13, is the first space telescope ... > full story -
Multiple Mergers Generate Ultraluminous Infrared Galaxy
June 29, 2012 — Ultraluminous infrared galaxies are the most luminous class of galaxies in the relatively near or local Universe. Most of their energy output is in the infrared range, suggesting that they contain a ... > full story -
Milky Way Struck 100 Million Years Ago, Still Rings Like a Bell
June 28, 2012 — Astronomers have discovered evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago, and as a result of that ... > full story
