The Edge

Canada-France-Hawaii Telescope/Coelum

Monday, June 30, 2014: Spiral galaxy NGC 891 shows the edge of its dust-disk as a thick dark lane in this image. Supernovae winds blow the dust out of the plane into an extended halo, with a pressure resulting from the sudden, violent explosion of young, massive stars. The signature blue light of these stars fated to end as supernovae shines throughout the whole disk.
