Astronomy Tuesday

What on earth (not on earth) has happened to this poor galaxy? Ring Galaxy AM 0644-741 is yet another victim of galaxy collision. A small intruder galaxy (still visible in the upper right corner of this image, trying to look like an innocent bystander) passed through what was once an ordinary spiral galaxy. The resulting gravitational disruptions destroyed the spiral arms and eventually led to that ring of bright blue new stars around the galactic core.
