ABOUT THIS IMAGE:
This NASA/ESA Hubble Space Telescope image reveals the vibrant core of the galaxy NGC 3125. Discovered by John Herschel on March 30, 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.
Located approximately 50 million light-years away in the constellation of Antlia (The Air Pump), NGC 3125 is similar to, but unfathomably brighter and more energetic than, one of the Magellanic Clouds. Spanning 15,000 light-years, the galaxy displays massive and violent bursts of star formation, as shown by the hot, young, and blue stars scattered throughout the galaxy's rose-tinted core. Some of these clumps of stars are notable - one of the most extreme Wolf-Rayet star clusters in the local Universe, NGC 3125-A1, resides within NGC 3125.
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.
