Summary
| Description |
English: In the constellation Sculptor lies this large extended spiral galaxy called NGC 289. Despite being around 75 million light-years away, the light of NGC 289 is stunningly captured here by the Dark Energy Camera (DECam) on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab. The galaxy’s bluish arms reach through the expanse of space over 100,000 light-years, larger than the size of our own Milky Way. It’s classified as a Type II Seyfert galaxy with its ripe collections of star formation and bright core, but it’s also relatively faint. Studies have found that the galaxy contains large amounts of dark matter, which is a common feature of all galaxies with a low surface brightness. Dark matter is yet to be directly observed, which led the US Department of Energy to build the DECam in order to study the nature of dark matter. Since the conclusion of its survey, DECam has been available to other scientists for use, such as for this image of NGC 289. |
