Discovered by British Astronomer William Herschel Over 200 years ago, the GALAXY NGC 2500 is about 30 million light-years away in the Northern Constellation of Lynx. As it shows this image of NASA’s Hubble Space Telescope, NGC 2500 is a particular type of spiral galaxy known as a spiral, with its fine arms spinning from a bright and elongated nucleus.

Spiral Galaxies are actually more common than ever before. About Two thirds of all spiral galaxies, including the milky way, exhibit these straight bars cutting through their centers. These cosmic structures act as bright nurseries for newly-Born Stars, and funnel material to the active core of a galaxy. NGC 2500 continues to actively form new stars, although this process seems to be happening in a very uneven way. The Upper Half of the galaxy where spiral arms are slightly better defined houses many more star formation regions than the lower half, as indicated by the bright and dotted islands of light.

There is another similarity between NGC 2500 and our galaxy of origin. Along with Andromeda, the triangle and many smaller natural satellites, the milky way is part of the local group of galaxies, a set of about 30 Galaxies United by gravity. NGC 2500 forms a similar group with some of its nearby neighbors, including NGC 2541, NGC 2552, NGC 2537, and the bright, Andromeda-as spiral NGC 2481 (collectively known as the NGC Group 2841).
