An article published in the journal “Nature” describes the most detailed observations of incredibly fast winds that travel at speeds of up to 71,000 km/s, nearly a quarter of the speed of light, near a supermassive black hole. A team of researchers used NASA’s NuSTAR and ESA’s XMM-Newton space telescopes to observe this phenomenon at the center of the galaxy IRAS 13224-3809 recording very quick temperature changes.
