NASA has released a new three-part composite image of 30 Doradus created to celebrate the Hubble telescope’s 22nd anniversary in orbit. It combines one image each from NASA’s great observatories; Chandra, Spitzer and Hubble. 30 Doradus is a large star-creating region in our neighboring galaxy, the Large Magellanic Cloud. Smack in the middle of 30 Doradus, thousands of stars are producing radiation and intense winds. Super hot gases from these winds and explosions are detected by the Chandra X-ray Observatory–here you can see these as blue. The Hubble image is green and shows the light of these huge stars and stages of star births. The Spitzer image can be seen in red, and shows cooler gas and dust formed by the powerful winds at the center. (Photo by NASA)
