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.
