Winner Takes All: Galaxies Headed for Collision on Intergalactic “Road of Matter”

Galaxies Are Headed For an Epic Collision on a Cosmic Matter Highway

Galactic 'bridges' could be the largest rotating structures ever discovered. Astronomers have uncovered evidence that cosmic filaments – tendrils of matter that stretch across hundreds of millions of light years – are also spinning. Rotation on such gigantic scales has never been observed before.

'Lonely cloud' bigger than Milky Way found in a galaxy 'no-man's land'. The so-called orphan or lonely cloud is full of hot gas with temperatures of 10,000-10,000,000 degrees Kelvin (K) and a total mass 10 billion times the mass of the sun. That makes it larger than the mass of small galaxies.
