Explanation: Galaxies dot the sky in this impressively wide and deep image of the Antlia Cluster. The third closest cluster of galaxies to Earth after Virgo and Fornax, the Antlia cluster is known for its compactness and its high fraction of elliptical galaxies over (spirals. Antlia, cataloged as Abell S0636, spans about 2 million light years and lies about 130 million light years away toward the constellation of the Air Pump (Antlia). The cluster has two prominent galaxy groups - bottom center and upper left -- among its over 200 galactic members, but no single central dominant galaxy. The vertical red ribbon of gas on the left is thought related to the foreground Antlia supernova remnant and not associated with the cluster. The featured image composite, taken from New Zealand, resulted from 150+ hours of exposures taken over six months.

Try as I might, I can only count 14! That is, spiral galaxies. Some of those rounder, smeary ones are probably galaxies too, but I can't distinguish blurry stars from globular galaxies. I'd need an astronomer to help me out!
Are we sure there aren’t worlds like ours in those galaxies? :-)
“Are we sure there aren’t worlds like ours in those galaxies?”
Hopefully not! It could mean there are 150 million Hillary Clintons out there...
In one of those worlds she'd be 50 points ahead...
Forget the cook book, yours is the best argument against trying to discover alien life in other galaxies.......
Aunt Leia..............
...And 150 million Obozos................
Amazing.
Magnificent!
Only 14? Every blurry smudge and spiral thing is a galaxy. There’s probably at least 30 or 40 easily identifiable in this picture. You can discount all the small blue dots, everything with diffraction spikes, and just about all the other smaller dots. You’re basically seeing the galaxy cluster through the nearby field of stars in our galaxy. It would be nice if they could edit them out.
And thousands in this old one from Hubble (animation lead-in to show where taken):
