Explore Arp 289: A Spiral Galaxy in the Constellation Crater

Arp 289 also known as NGC 3981 and PGC 37496 stands out as a spiral galaxy located in the constellation Crater. It was discovered on February 7 1785 by the astronomer William Herschel and is positioned at an astonishing distance of 62 million light years away from our planet.

Arp 289 is a part of the NGC 4038 Group within the vast Virgo Supercluster. This galaxy stretches over 120,000 light years and is classified as having wind effects based on the esteemed Arp Catalogue of peculiar galaxies.

Using the Very Large Telescope (VLT) we have captured inspiring images of Arp 289s intricate spiral arms. These images unveil a network consisting of extensive gas streams, dust and regions where stars are actively forming within this galaxy. Additionally there is a disk comprised of young and hot stars that beautifully contrasts against the cosmic backdrop.

What sets Arp 289 apart is its inclination relative to Earth. This orientation grants us a view, into its center where a supermassive black hole resides. Arp 289 holds a place among celestial objects due to its unique features.

The Spiral Structure of Arp 289; Indications of Interactions between Galaxies

The captivating spiral structure of Arp 289 is truly remarkable. It suggests that the galaxy has experienced influences from past encounters or potential gas stripping caused by ram pressure while traversing through the intergalactic medium.
