“NGC 2976 does not look like a typical spiral galaxy, as this NASA/ESA Hubble Space Telescope image shows.
In this view of the oddball galaxy’s inner region, there are no obvious spiral arms. Dusty filaments running through the disc show no clear spiral structure. A raucous interaction with a neighbouring group of hefty galaxies stripped away some gas and funneled the rest to the galaxy’s inner region, fueling star birth about 500 million years ago. At the same time, the galaxy’s outer regions stopped making stars because the gas ran out. Now, the inner disc is almost out of gas as new stars burst to life, shrinking the star-formation region to a small area of about 5,000 light-years around the core.”
