Astronomers claim to have discovered a giant cloud of gas surrounding the milky way, which is essentially invisible and was only seen by X-ray light being absorbed by charged oxygen atoms around the milky way. They claim that most galaxies could be surrounded by this "invisible" gas cloud.

If this does answer the missing baryon problem, then does this mean dark matter can be entirely forgotten about?

But that invisible gas does not add up to 5.25 times as much matter as visible matter.

Thank you very much, I wish I'd seen this before I had posted my question. I feel like mine is now taking up unnecessary space and needs deleting.
