NGC 2146, Starburst Galaxy

NGC 2146 in the constellation of Camelopardalis was discovered in 1876 by Friedrich Winnecke as by product of comet research. It is a barred spiral galaxy with a diameter of 80 000 light years that is situated about 70 million light years from Earth. The galaxy shines with an apparent magnitude of 11.38 and is 6 by 3.5 arc minutes. The dust lanes in the spiral arm that is covering the core are very apparent. The 45° bend arm is believed to be the byproduct of a close encounter with another galaxy about 0.8 billion years ago. This close encounter formed high rates of star formation so NGC 2146 qualifies as a starburst galaxy.
