Hubblecast 60: Galaxy scores a bullseye

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.br br More information and download-options:br br Credit:br ESAHubblebr Visual design and editing: Martin Kornmesserbr Web and technical support: Mathias Andre and Raquel Yumi Shidabr Written by: Oli Usherbr Narrator: Sara Mendes da Costabr Images: NASA, ESA, Chandra X-ray Observatory, Digitized Sky Survey 2br Visualisations and animations: B.
