2 days ago · Astronomers have discovered colossal black hole jets, named Porphyrion, stretching 23 million light years across, far surpassing our Milky Way in size. This astounding discovery, made using radio telescopes like ASKAP and LOFAR, reveals how supermassive black holes launch jets that travel nearly at the speed of light, despite cosmic obstacles.
3 days ago · This is an artist's concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet.
4 days ago · Hubble’s observations opened the door to a universe full of black holes, pinpointing dazzling bright, black hole-powered galactic nuclei called “quasars” at the centers of galaxies and making the first-ever confirmation of the presence of a suspected supermassive black hole at the center of a galaxy.
3 days ago · JAXA’s XRISM X-ray telescope captured the distribution of matter falling into the supermassive black hole in galaxy NGC 4151 over a wide radius, spanning from 0.001 to 0.1 light-years. By determining the speed of the iron atoms from their X-ray signature, scientists have mapped out a sequence of structures surrounding the central ‘monster ...
