ANd NOW, they're dicking around closer to home, witht he Milky Way its own self!

"We call it home, but the Milky Way can still surprise us. It does not have just one halo of stars, as we thought, but two. The finding calls into question our theories for how our galaxy formed.
Daniela Carollo at the Torino Observatory in Italy and her colleagues were measuring the metal content and motion of 20,000 stars in the Milky Way, observed by the Sloan Digital Sky Survey, when they made their discovery.

They found that the halo can be divided into two distinct regions, rotating in opposite directions, and containing stars of different chemical composition. "We really weren't expecting to see anything like this," says Carollo.

The team found that the inner halo is flattened and extends out to about 4.6 x 1017 kilometres from the galactic centre, rotating at 20 kilometres per second, in the opposite direction at about 70 kilometres per second."
