Previous HST image I think
Longer Exposure

Feast your eyes and look at all those little blue dots. This is incredible!!! This has to be really big news!
I imagine that those are the central structures of galaxies. Maybe AGNs. Black holes forming. Your guess is as good as mine. Whatever they are I am sure that nobody expected them in those numbers.
Is this a cluster of galaxies, or it could be a single galaxy that is spread out?
What do you guys think? I think we are going to need a bigger telescope!
You can tell that the gravitational lens has a higher density of the tiny blue dots near the center of the cluster than further away probably due to the lens. In this crop the center of the cluster is on the right hand side of the image. If they are blue in these filters this must mean that they are in the UV or even x-ray regime, right? It will be interesting to get a spectrum of these things.
