| Notes | M 82 was first observed by Johann Bode of the Berlin Observatory on December 31, 1774, the same night he discovered nearby M81. This object lies at a distance of about 10 million light years from earth and measures nearly 16,000 light years across its length, making it a rather small galaxy. Current theory suggests that M82 is being severely disturbed by tidal forces from its larger neighbor, M81, resulting in areas of intense star formation within the galaxy. This image was the result of a collaborative effort between Dave Jurasevich and David Held. |
