An astronomer from Liverpool John Moores University has discovered a new family of stars in the core of the Milky Way which provides new insights into the early stages of the galaxy’s formation. The discovery has shed new light on the origins of globular clusters formed at the beginning of the Milky Way’s history.
Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters — and the example shown in this NASA/ESA Hubble Space Telescope image, named NGC 362, is one of the most unusual ones.
This NASA/ESA Hubble Space Telescope image reveals the vibrant core of the galaxy NGC 3125, approximately 50 million light-years away. 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.
