| Description |
M82 is one of the strangest looking nearby galaxies.
Its exact structure remains a mystery. It has long been described as an
irregular galaxy, but it is also possible that M82 is an entirely normal
edge-on spiral with an obscure unidentified foreground object in our line
of sight. |
