Ring Galaxy AM 0644-741 from Hubble |
| Explanation |
How could a galaxy become shaped like a ring? The rim of the blue galaxy pictured [ http://heritage.stsci.edu/2004/15/caption.html ] on the right is an immense ring-like structure 150,000 light years [ http://chandra.harvard.edu/photo/cosmic_distance.html ] in diameter composed of newly formed, extremely bright, massive stars. That galaxy, AM 0644-741 [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1997ApJ...474..686H ], is known as a ring galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap010612.html ] and was caused by an immense galaxy collision. When galaxies collide [ http://antwrp.gsfc.nasa.gov/apod/ap020506.html ], they pass through each other -- their individual stars rarely come into contact. The ring [ http://www.engagement-rings-guide.com/engagement-rings-history.html ]-like shape is the result of the gravitational disruption [ http://www.astro.umd.edu/~dcr/Research/tidal.html ] caused by an entire small intruder galaxy passing through a large one. When this happens, interstellar gas and dust [ http://antwrp.gsfc.nasa.gov/apod/ap030706.html ] become condensed, causing a wave of star formation [ http://www.sciam.com/askexpert_question.cfm?articleID=0008A68A-8C7F-1C72-9EB7809EC588F2D7 ] to move out from the impact point like a ripple across the surface of a pond. The intruder galaxy has since moved out of the frame taken by the Hubble Space Telescope [ http://www.stsci.edu/hst/HST_overview/ ] and released to commemorate [ http://hubblesite.org/newscenter/newsdesk/archive/releases/2004/15/image/a ] last Saturday's fourteenth anniversary of Hubble's launch. Ring galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap020909.html ] AM 0644-741 lies about 300 million light years away. |
