'We don't understand what it looks like': Astronomers baffled by 'almost invisible' dwarf galaxies that boost dark matter theory

Scientists have discovered an „almost invisible” dwarf galaxy that our current understanding of the universe cannot explain. The mysterious faint object that went undetected for years is so faint that researchers can't even pinpoint its exact location.

The new galaxy, named Nupe (or „cloud” in Spanish), is described in a study published in the journal Jan. 9. Astronomy & Astrophysics. The Nube is very diffuse, meaning its stars are spread out so widely that, as a result, the galaxy does not emit any light. It is about 10 times fainter than other known dwarf galaxies and 10 times wider than it should be considering the number of stars it contains.
