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.

'Extreme' white dwarf sets cosmic records for small size, huge mass

'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.
