NASA’s Chandra X-Ray Observatory has been providing invaluable data since it reached orbit in 1999. In the picture below, pieced together from 22 pointings over nearly two weeks of observing time, Chandra images the spectacular Carina Nebula. A star-forming region only about 7,500 light years from Earth, Carina also appears to be ramping up its production of supernovae, evidenced by diffuse x-ray emissions, an increasing number of post-novae neutron stars, and the appearance of a number of massive young stars that are likely to end as supernovae.
