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.

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.
