Hubble Space Telescope finds surprising number of black holes in early universe
NASA's Hubble Space Telescope helped astronomers find more supermassive black holes in the early universe than previous estimates.
Biggest black hole jets ever seen span 140 Milky Way galaxies
An artist's illustration of the longest black hole jet system ever observed. Nicknamed Porphyrion after a mythological Greek giant, these jets span roughly 7 megaparsecs, or 23 million light- years. That is equivalent to lining up 140 Milky Way galaxies back-to-back.

Researchers spot largest black hole jets ever discovered
Now, researchers are getting a clearer picture of just how far outside of the galaxy their influence can reach. A new study describes the largest-ever jets observed, extending across a total distance of 23 million light-years (seven megaparsecs).
Black hole’s jets are so huge that they may shake up cosmology
Spanning 23 million light years, or 220 Milky Way galaxies, a set of giant, newly discovered black hole jets known as Porphyrion may change our understanding of black holes and the structure of the un
A Black Hole Was Observed Creating the Largest Cosmic Megastructure Ever Seen
Black holes suck in anything and everything that comes near them, even light cannot escape after crossing one of their event horizons, However they also produce massive outflows of plasma and one of those astrophysical jets just produced the largest megastructure ever observed.
