The two biggest black holes ever discovered have been found to be 10 billion times the size of our Sun.

SCIENTISTS HAVE DISCOVERED THE two biggest black holes ever observed, each with a mass billions of times greater than the Sun's, according to a new study published.

The two giants are located in the heart of a pair of galaxies several hundred million light years from Earth, said the study in scientific journal Nature.

Each black hole is estimated to have a mass about 10 billion times greater than the Sun, dwarfing the previously largest-known black hole, which has a mass of 6.3 billion suns.

The University of California, Berkeley, team led by Nicholas McConnell and Chung-Pei Ma said one black hole is located in NGC 3842, the brightest of a cluster of galaxies about 320 million light years from Earth.

The second hole is of "comparable or greater mass" and is located in NGC 4889, the brightest galaxy in the Coma cluster, about 335 million light years away.

RESEARCHERS HAVE DISCOVERED and mapped two enormous energy flows streaming out at supersonic speeds from the centre of the Milky Way.

The outflows, which were detected with CSIRO's 64m Parkes radio telescope, in NSW, are made up of hot gas and plasma, cosmic rays and magnetic fields. They are pouring from the centre of our galaxy at speeds of up to 1000km/s.

The finding, published in the journal Nature, follows the discovery of the Fermi bubbles: two giant bubbles of gas and energy that were detected by an international team of astronomers in 2010 using NASA's Fermi gamma-ray telescope.

Monster Quasar Discovered with Power Outflow 100 Times Milky Way Galaxy

Researchers have discovered a quasar known as SDSS J1106+1939 with the most energetic outflow ever, a finding that may answer questions about how the mass of a galaxy is linked to its central black hole mass and why there are so few large galaxies in the universe. The rate that energy is carried away by the huge mass of material ejected is equivalent to two trillion times the power output of the sun. The black hole at the heart of quasar SDSS J1106-1939 is massive, estimated to be a thousand times heavier than the black hole in the Milky Way.
"This is about 100 times higher than the total power output of the Milky Way galaxy — it's a real monster outflow," said Nahum Arav, an associate professor of physics in College of Science at Virginia Tech and leader of the research team, which includes Benoit Borguet, now a postdoctoral researcher now at the University of Liege, Belgium; Doug Edmonds and Carter Chamberlain, both graduate research assistants at Virginia Tech, and Chris Benn, a collaborator who works with the Isaac Newton Group of Telescopes in Spain.

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen a key stage in the birth of giant planets for the first time. Vast streams of gas are flowing across a gap in the disc of material around a young star. These are the first direct observations of such streams, which are expected to be created by giant planets guzzling gas as they grow. The result is published on 2 January 2013 in the journal Nature.
