NGC 2146, classified as a barred spiral galaxy, is undergoing massive amounts of star formation. In addition of being barred, NGC 2146 is also considered a starburst galaxy due to its intense amount of star formation. Though it is smaller than the Milky Way, its rate of star production is orders of magnitude grater than that of the Milky Way. Credit: NASA/Harvard/Hubble/NED/ESA
