Description

This image captures 2 Astrobin Debut Objects located 155 million light years away in the constellation of Leo at a declination of +10 degrees.

Arp 232, also known as NGC 2911, is the large lenticular galaxy at upper right. This galaxy was classified by Dr. Arp into the odd category of Galaxies with Appearance of Fission. This magnitude 11.5 galaxy spans 3.5 arc-minutes in our apparent view, which corresponds to a diameter of 150,000 light years.

I love the fascinating dust cloud structure seen in the lower right half of the galaxy disk. I believe that these dust clouds extend throughout the disk, but are obscured from our view on the far side by the bright halo of stars around the core. The small blue dwarf to the left, at 13,000 light years in diameter, is the same distance away.

Arp 137, also known as NGC 2914, is the deformed barred spiral galaxy at lower left. My Astrobin image post which focuses on Arp 137, including an Arp comparison image for it, is here. The interesting structure of this galaxy resembles a ring as its 2 strong arms extend around the outer disk.

The galaxy at the bottom of the image is the interesting grand design spiral UGC 5093, just a few million light years further away than the other galaxies.
