This is just super, super misleading and ugh. GATHER ROUND KIDDES ‘CAUSE YA GONNA LEARN SOME SPACE STUFF.
This picture is of the dark nebula known as Barnard 68. It’s a cloud of gas that’s relatively close to us (500 light years away), so it’s between us and most stars. You can’t see the stars behind it because of the density/color of the gas.
Also, there would be no way to know if there was or was not dark matter in it. We’re still not sure that dark matter even EXISTS. Let alone be able to detect it.
Plus here’s an infrared picture showing the stars behind it. In case ya still thought I was lying.

BUT WAIT. The Eridanus Supervoid could possibly(okay not really) be a thing. The source leads you to a thing called the CMB Cold Spot. Its not nearly as spectacular if you read up on it. Cold spots are pretty common, actually. Also, there’s very little evidence that the cold spot is caused by a supervoid, as a matter of fact its very unlikely. Most believe the CMB cold spot to be an average, insignificant, cold spot in the cosmic radiation map. So basically, the actual supervoid that this post is referencing probably doesn’t even exist, but I digress.
