Ancient stellar collisional ring galaxy forms stars 50 times faster than Milky Way
Researchers have found a rare and massive collisional ring galaxy from some 10.8 billion years ago that is forming stars 50 times faster than the Milky Way, says York University Postdoctoral Fellow Leo Alcorn of the Faculty of Science. These kinds of ring galaxies are formed when one galaxy collides with another galaxy that passes through its centre.
