Intergalactic Wanderer, Joke Olateju

Intergalactic Wanderer

The Intergalactic Wanderer, also known as NGC 2419, is one of the most distant globular clusters in our galaxy, it is more than 250,000 light years away. This cluster, listed fourth in intrinsic brightness, because of its distance appears faint in our skies. It lies in the direction of the galactic anticenter, nestled in the constellation of the Lynx. It was discovered by William Herschel on December 31, 1788. In fact, The Large Magellanic Cloud,a satellite galaxy, is closer to our galactic center than this cluster. It has been suggested that the Wanderer may actually be an object that belongs to no particular galaxy

This photograph was taken with four filters, to let in clear, red, blue, and green light. All pictures with filters had the same exposure time. As the yellow emitted light suggests, the Intergalactic Wanderer is old. All the bright blue stars have burned out (note the few remaining almost pink stars) and those that remain are not as high in temperature as they once were. This photograph is meant to show the nature of the Intergalactic Wanderer and therefore has been significantly enhanced and enlarged, it truly has an angular size of about 4 arcminutes. With an linear size of approximately 83 light years.
