Image Data

Designation NGC 6769 (upper right),  NGC 6770 (upper left) and NGC 6771 (below)
Object type Interacting galaxy trio
Coordinates 19 h 19 min    - 60° 31'   (Pavo)
Description Located towards the far southern constellation of Pavo (the Peacock), this cosmic tango is happening 190 million lightyears away.  While NGC 6769 seems pretty intact, its neighbour shows heavily disturbed spiral arms. All three galaxies display a similarly bright central bulge. The squarish shape of NGC 6971 is a rare occurrence among galaxies.  As a result of the interactions many new stars have been born (blue regions) and a lot of starforming regions (pink) are readily apparent.

These galaxies are mag 12.4, 12.4 and 13.4 respectively. The field of view is 10 x 15 arcminutes with north towards the top.
