APOD 3.7- Sideways Galaxy NGC3628

The NGC 3628 galaxy appears almost as the shape of a line in the night sky, however this galaxy is actually a spiral galaxy seen from its side from the perspective from Earth. The Sideways Galaxy is located in the constellation Leo nearly 35 million light years away and is approximately the size of the Milky Way Galaxy. There are hints of red in the galaxy's star-forming regions. The shape of the galaxy seems to fan out at the edges while a faint arm is extended to the upper left, which suggests that this spiral galaxy is interacting with other members of the Leo triplet galaxies, M66 and M65. NGC 3628 has a tidal tail extending 300,000 light years from the edge of the disk. The tail, full of blue star clusters and star-forming regions, is drawn out from the galaxy because of past interaction with other galaxies.This galaxy is not in Charles Messier's catalog, although it is a member of the Leo triplet galaxies.
