Executive Summary
- Hubble's image reveals the unique structure of Arp 184, a peculiar spiral galaxy with a prominent spiral arm, located 190 million light-years away.
- Arp 184 is part of the Atlas of Peculiar Galaxies, known for its odd shape and its active history of supernovae events.
- The Hubble image combines data from multiple observing programs, highlighting both Arp 184's unusual appearance and the aftermath of supernovae.
Event Overview
The Hubble Space Telescope has captured a new image of Arp 184, also known as NGC 1961, a peculiar spiral galaxy located 190 million light-years away in the constellation Camelopardalis (The Giraffe). This galaxy, cataloged in the Atlas of Peculiar Galaxies by Halton Arp, stands out due to its single broad, star-speckled spiral arm that appears to stretch towards the viewer, creating a three-dimensional effect. Its active history of supernovae makes it a valuable target for astronomers studying the origins of heavy elements and cosmic expansion.
