Hubble views a galaxy fit to burst
This NASA/ESA Hubble Space Telescope image reveals the vibrant core of the galaxy NGC 3125. Discovered by John Herschel in 1835, NGC 3125 is a great example of a starburst galaxy—a galaxy in which unusually high numbers of new stars are forming, springing to life within intensely hot clouds of gas.

Despite their appearance, the fuzzy white blobs dotted around the edge of this galaxy are not stars, but globular clusters. Found within a galaxy's halo, globular clusters are ancient collections of hundreds of thousands of stars. They orbit around galactic centers like satellites—the Milky Way, for example, hosts over 150 of them.
