NGC 5970 is a large barred-spiral galaxy located about 90 million light years away in the constellation Serpens Caput. It appears to have two satellite or companion galaxies. It is a member of the Virgo Cluster of galaxies.[2] It was discovered on March 15, 1784, by the astronomer William Herschel.[5]
LINER-type emission has been detected from the disk of NGC 5970.[6]
Observations
NGC 5970 can be seen 1° southwest of the star Chi Serpentis. A faint halo of dust can be seen around the galaxy's outer spiral arms.
