Hubble peers into the heart of the Milky Way

1 April 2016 Astronomy Now

Peering deep into the heart of our home galaxy, the Milky Way, the Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Most of the stars pictured in the image are members of the Milky Way nuclear star cluster, the densest and most massive star cluster in the galaxy. Hidden in the centre is the Milky Way’s resident supermassive black hole.

Theoretical study concludes most Earth-like worlds have yet to be born

Earth came early to the party in the evolving universe. According to a new theoretical study, when our solar system was born 4.6 billion years ago only eight percent of the potentially habitable planets that will ever form in the universe existed. And, the party won’t be over when the Sun burns out in another 6 billion years. The bulk of those planets — 92 percent — have yet to be born.
