Strange 'twin' new worlds found (BBC) {"planemos"}
A pair of strange new worlds that blur the boundaries between planets and stars have been discovered beyond our Solar System.

A few dozen such objects have been identified in recent years but this is the first set of "twins".

Dubbed "planemos", they circle each other rather than orbiting a star.

Their existence challenges current theories about the formation of planets and stars, astronomers report in the journal Science.

"This is a truly remarkable pair of twins - each having only about 1% the mass of our Sun," said Ray Jayawardhana of the University of Toronto, co-author of the Science paper.

2. Can I come?
This is really weird. I can understand one forming out of a bit of gas-cloud leftover, but twins in a stable orbit? Freaky.
