NGC 3758 known as the Owl Galaxy,[1] is a type Sb[2] spiral galaxy in the constellation of Leo.[3][4] It is located 447 million light-years from the Solar System and an approximate diameter of 70,000 light-years.[5] NGC 3758 was discovered by Ralph Copeland on March 18, 1874, but also independently discovered by Edouard Stephan ten years later.[1]

Description

NGC 3758 is classified as a Seyfert 1 type galaxy.[5][6] It is classified a Markarian galaxy (designated Mrk 739), because compared to other galaxies its nucleus emits excessive amounts of ultraviolet rays.[7] It is a binary active galactic nucleus galaxy, a rare example of a galaxy merger.[8][9]

NGC 3758 is made up of two separate galaxies, NGC 3758W[10] and NGC 3758E.[11] Each of the two galaxies has a supermassive black hole, which is only 11,000 light-years apart and gorging on infalling gas.[12] Both black holes are active, in which large amounts of gas is sent spiraling inward, which it becomes hot and radiates energy.[9] The galaxies are gravitationally bound together and such, their orbits will dynamically decay until their nuclei merge in which the process takes a few billion years.[13]

The galaxy has an appearance of a friendly-looking object complete with two cores as the eyes and a swirling grin.[12] It is possible that binary black holes on the verge of merging in NGC 3758 can turn stars into hypervelocity stars and catapult them out of their host galaxy.[14]

NGC 3758 contains an extended emission-line region (EELR), which was discovered in the Galaxy Zoo project. This EELR could originate from both AGN or from just one. Detailed oxygen [O III] imaging could reveal which AGN is responsible for this EELR.[15] ESO's VLT MUSE instrument is capable of such observations and MUSE did observe NGC 3758 in 2016,[16] but no publication about the MUSE data concerning the EELR exists as of May 2024.
