Description

Abell 1060 is a galaxy cluster in the Hydra constellation, around 190 million light years from earth.

As is often the case, the two bright stars in the frame are nowhere near the galaxies (distance wise) and are performing a cosmic photobomb in the foreground.

An interesting fact about this specific cluster is that from a gravitational standpoint, it shouldn't exist. Roughly 83% of the matter necessary to explain the gravitational interactions just isn't there. This is the infamous "dark matter" you might have heard of (which in essence is just a collection name to indicate that we don't really know what's going on). Time will hopefully tell/reveal.
