View Full Version : Second Black Hole at the Heart of the Milky Way

2005-Sep-12, 02:10 AM
SUMMARY: A French/US team of astronomers have discovered a second black hole is lurking at the heart of our Milky Way galaxy, completely separate from the supermassive black hole that we've known about for years. This new object, IRS 13E, contains only 1,400 stellar masses, which is much less that the 4 million stellar masses of our supermassive black hole. IRS 13E probably used to be located far away from the galactic centre, where a cluster of stars could safely form. All that's left now are a few massive stars whipping around the black hole as it spirals towards the centre of our galaxy.

Will this black hole meet up with the supermassive one? And does 1 BH plus 1 BH = 1 BH?
