Brightest star explosion ever seen


Supernova SN 2006gy in space

From NASA in the USA:

The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA’s Chandra X-ray Observatory and ground-based optical telescopes.

This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own galaxy.

“This was a truly monstrous explosion, a hundred times more energetic than a typical supernova,” said Nathan Smith of the University of California at Berkeley, who led a team of astronomers from California and the University of Texas in Austin.

“That means the star that exploded might have been as massive as a star can get, about 150 times that of our sun. We’ve never seen that before.”

  1. Scientists trap antimatter

    Thursday 18 November 2010

    Scientists claimed a breakthrough today in successfully trapping the first “anti-atom” in a quest to understand what happened to all the antimatter that has vanished since the Big Bang.

    A team of physicists at the European Organisation for Nuclear Research created an atom of anti-hydrogen and demonstrated that it can be studied in the lab.

    The next step will be to compare matter and anti-matter, the team said.

    Theory posits that matter and antimatter were created in equal amounts at the moment of the Big Bang, which scientists believe spawned the universe some 13.7 billion years ago. But while matter – defined as having mass and taking up space – went on to become the building block of everything that exists, antimatter has all but disappeared except in the lab.
