NGC 2336 is a typical galaxy: large, beautiful, and blue. However, there is also something special about it. This barred spiral galaxy spans a whopping 200,000 light years across and is located about 100 million light years from Earth. The space object is located in the northern constellation Camelopardalis (Giraffe).
Its spiral arms are inhabited by young stars, easily distinguished by their bright blue light. In contrast, the redder central part of the galaxy is dominated by older yellow and red stars.
NGC 2336 was discovered in 1876 by German astronomer Wilhelm Tempel using a 28-centimeter telescope. The image that Hubble provided is much better than what Tempel would have. The fact is that the main mirror of the Hubble is 2.4 meters in diameter. This is almost ten times the size of the telescope that Tempel used.
In 1987, a Type Ia supernova occurred in NGC 2336, the only supernova observed in the galaxy since its discovery 111 years earlier.
Recall that a type Ia supernova is a subcategory of supernovae, which, in turn, are a subcategory of cataclysmic variable stars. A type Ia supernova appears as a result of a thermonuclear explosion of a white dwarf.
