A Rare Glimpse of the Dark Universe

"This cloud is a window into the dark Universe," explained team member Andrew Fox of AURA/STScI for the European Space Agency. "We know from theory that most of the mass in the Universe is expected to be dark matter, but it's difficult to detect this dark material because it doesn't emit light. Cloud-9 gives us a rare look at a dark-matter-dominated cloud."

Cloud-9 belongs to a category known as Reionization-Limited H I Clouds, or "RELHICs." The term "H I" refers to neutral hydrogen, while "RELHIC" describes a hydrogen cloud formed in the early Universe that never progressed to form stars. Scientists had predicted the existence of such objects for years, but direct confirmation remained elusive. Only after observing Cloud-9 with Hubble were researchers able to verify that it truly contains no stars.

Take out burrito, vegetable wrap with chicken, taco bowl, French fries, and Cole slaw. Had to pick it up early since I am no longer allowed to drive at night, much to the benefit of everyone else.
