The earliest galaxies may have scrambled our reading of the Universe. A new study challenges the traditional interpretation of the cosmic microwave background, this fossil light from the Big Bang.

Using its bright galactic core, known as a quasar, this unsporting galaxy fires a beam of energy powered by a supermassive black hole through its opponent's core. With each pass, more of the ...

AT2024tvd could also be a former member of a triplet of black holes that used to be at the galactic core. Because of the chaotic nature of three-body orbits, one would have been kicked out of the ...
