Infrared composite image of NGC 6334, the Cat's Paw Nebula.

In this composite infrared image of NGC 6334, pink shows gas and dust that make up the nebula, illuminated by bright high-mass stars. Many young stars appear yellow to red and most are found buried within the dark clouds extending from the upper left to the lower right. High-mass stars peek into view by carving out bubbles within the dense clouds of gas and dust that formed them. Click on the image for a high-resolution version.

Scorpius is one of the few constellations I can regularly pick out in the summer sky. It often sits low on the southern horizon, with two bright stars marking its pincers and the red multiple star Antares highlighting its long body.

Scorpius, I learned last week, also is home to a star nursery. It’s difficult for amateurs to see, but Iowa State University graduate student Sarah Willis says it’s one of the Milky Way’s most active star-forming regions. In a paper delivered last week at the American Astronomical Society meeting in Indianapolis, Willis described this “star burst,” which is generating tens of thousands of new objects.
