Hubblecast 60: Galaxy scores a bullseye
The ESA astronomy podcast bringing you the latest from the Hubble Space Telescope
6 December 2012
Episode 60 of the Hubblecast explores NGC 922, a galaxy that has been hit square-on by another. Ripples of star-formation are still propagating out across thousands of light-years of space over 300 million years after the collision, making it a prime example of what astronomers call a collisional ring galaxy.
