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.

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.
