The X post from Daily Mail US uses a sensational headline about "powerful UFOs blasting out of a monster black hole" to promote an article on a new astronomical observation in the distant quasar WISSH13, over 11 billion light-years away.
In scientific terms, UFOs refers to ultra-fast outflows—streams of superheated, ionized gas detected via XMM-Newton and NuSTAR X-ray telescopes—with components moving at 10% and 30% the speed of light, ejecting over 40 solar masses of material per year in a layered structure.
The discovery, from when the universe was about 2 billion years old, highlights how these energetic winds from supermassive black holes can heat and expel gas, potentially regulating star formation and influencing early galaxy evolution.
