Current Date & Time:
The Leo Triplet (LRGB)
This photogenic grouping of bright galaxies lies in the constellation Leo and is made up of NGC 3628 (left), M65 or NGC 3623 (upper right), and M66 or NGC 3627 (lower right). Occupying a field of view less than 1 degree wide, this group lies at a distance of about 30 million light years and the three galaxies are physically related. NGC 3628 and M66 show evidence of a previous encounter and M65 appears largely unaffected by its immediate neighbors.
