SUMMARY: The latest image released from the Chandra X-Ray Observatory shows the centre of M17, (a.k.a. the Horseshoe Nebula) in the constellation of Sagittarius. The resolution of Chandra is so high that it can pick out the group of massive young stars which are heating the surrounding gas from 1.5 million to 7 million degrees Celsius. The stars in the nebula are only a million years old, so the nebula is too young for one of its stars to have exploded as a supernova and heated the gas.

I made a mistake with this story. I said it was in the constellation Orion, but it's not, it's the constellation Sagittarius. Sorry about that.
