Coldest brown dwarfs blur lines between stars and planets

more »

Astronomers are constantly on the hunt for ever-colder star-like bodies, and two years ago a new class of such objects was discovered. However, until now no one has known exactly how cool their surfaces really are -- some evidence suggested they could be room temperature. A new study shows that while these brown dwarfs, sometimes called failed stars, are warmer than previously thought with temperatures about 250-350 degrees Fahrenheit.

Powerful jets blowing material out of galaxy: Process limits growth of central black hole and rate of star formation

more »

Astronomers using a worldwide network of radio telescopes have found strong evidence that a powerful jet of material propelled to nearly light speed by a galaxy's central black hole is blowing massive amounts of gas out of the galaxy. This process, they said, is limiting the growth of the black hole and the rate of star formation in the galaxy, and thus is a key to understanding how galaxies develop.

Phoenix on Space Star backdrop - Trifid Nebula Samsung Galaxy S3 Cover

Phoenix on Space Star backdrop - Trifid Nebula Samsung Galaxy S3 Cover

Galaxies, Stars and Nebulae series A fantastic picture from our universe featuring the massive star factory known as the Trifid Nebula.

It was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in northern Chile.
So named for the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future. The field of view of the image is approximately 13 x 17 arcminutes.
It's an awe-inspiring, breathtaking image that reveals some of the wonder that is our universe.
