Astronomers have found a distant quasar illuminating a vast nebula of diffuse gas, revealing for the first time part of the network of filaments believed to connect galaxies in a cosmic web.
Researchers have claimed that "fast radio bursts", lasting for only a thousandth of a second, may be coming from within our own galaxy, and not from galaxies billions of light-years away as previously believed.
Researchers have identified a group of more than 675 stars on the outskirts of the Milky Way that they argue are hypervelocity stars that have been ejected from the galactic core.
