Three New Extrasolar Planets Discovered

Astronomers using the 4-m Anglo-Australian Telescope (AAT) near Coonabarabran, Australia have discovered three new planets orbiting distant stars. The first is known as a "hot Jupiter", 84% the size of Jupiter, but extremely close to its star. The second lies in an almost Earthlike orbit, where liquid water could exist; however, it's also a Jupiter class planet, so almost certainly a gas giant. The third planet is almost twice the size of Jupiter, and orbits out past the distance of Mars from the Sun.

New Type of Galaxy Discovered!

Australian astronomers believe they have found evidence that the earliest stars in the Universe may be much older than originally thought following the discovery of an entirely new type of galaxy. Using CSIRO's Australia Telescope and the Hubble Space Telescope, the team found "galaxies that are absolutely fizzing with star formation - a sort of huge stellar baby-boom". These galaxies, or "starbursts" are hundreds of times more active than regular galaxies
