New research shows how the 'dancing' behaviour of dwarf satellite galaxies can predict mergers between their hosts. A distant pair of galaxies is undergoing the same type of merger that Milky Way/Andromeda will undergo. Can the behaviour of their dwarf satellites tell astronomers what will happen when the MW and Andromeda merge?

A stunning new image of a cosmic jet has helped astronomers unlock the mystery behind the unusually bright emission of high-energy gamma rays and neutrinos from a peculiar celestial object. The source is a blazar—a type of active galaxy powered by a supermassive black hole devouring matter at the heart of a galaxy. They have captured what looks like the mythical "Eye of Sauron" in the distant universe and may have just solved a decade-long cosmic puzzle.

While observing the Halley-type comet 12P/Pons-Brooks with ALMA and NASA's Infrared Telescope Facility, researchers determined that the comet's water is strikingly similar to the water on Earth.
