NGC 3310

NGC 3310NGC 3310 is a grand design spiral galaxy in the constellation Ursa Major. It is also a starburst galaxy. (Starburst galaxies are undergoing an exceptionally high rate of star formation.) NGC 3310 probably collided with one of its satellite galaxies about 100 million years ago, triggering widespread star formation. The ring clusters of NGC 3310 have been undergoing starburst activity for at least the last 40 million years.

A Grand Design Spiral Galaxy

NGC 2608 (also known as Arp 12) is considered a grand design spiral galaxy because the galaxy’s arms wind moderately (neither tightly nor loosely) around its prominent central bar. It is about 93 million light-years away in the constellation Cancer and is 62,000 light-years across, roughly 60% of the width of the Milky Way.

The Core of M100

Messier 100 is a spiral galaxy located within the southern part of constellation Coma Berenices about 55 million light-years away. It’s about 107,000 light-years in diameter and one of the brightest and largest galaxies in the Virgo Cluster. The image of the galaxy’s core shown above was taken by the Hubble Space Telescope in 2009.
