Heart of our Milky Way galaxy.
It's been 10 months since the Mars Exploration Rovers arrived at the Red Planet, and their full suite of scientific tools are still working perfectly. Spirit is now discovering further evidence of past water on a slope of layered bedrock, which was once layers of volcanic ash altered by water over a long period. Opportunity is heading towards the base of "Burns Cliff", a tall exposure of layered rock in wall of Endurance Crater. The rover is taking advantage of a mysterious power boost that happened about a month ago to get more scientific work done.
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.
