This is a crazy scene with many interesting
Astrobin Debut Objects located in the constellation of Corona Borealis at a declination of +38 degrees. This is one of those amazing fields of view where the distant background galaxies outnumber the stars. The mouseover shows the 4 galaxies that I found most interesting.
My favorite, at bottom, is the pairing of UGC 10346 (in-line to the star stream) and 2MASS J16200160+3735181 (transverse to the star stream). Both of these galaxies are 1 billion light years away. A 400,000 light year long star stream connects both disks. The bright disks themselves are each 60,000 light years in diameter. I love how the star stream is a bit offset as it crosses the 2MASS galaxy. These 2 galaxies look to be in the initial stages of a merger, a bit like
Arp 295.
The 3 NGC galaxies highlighted at top are each fascinating - the edge-on NGC 6122, the near edge-on NGC 6119, and particularly the merger ball of NGC 6120. NGC 6120 looks to be 2 galaxies in the end stages of a merger, with blue and yellow core components and no tails left. It is almost 0.5 billion light years away and is 70,000 light years in diameter. I am surprised that this object did not make Dr. Arp’s peculiar galaxy catalog. It reminds me of
IC 2520.
