Astronomers observe real-time formation of black hole jets for the first time
In 2018, a galaxy about 270 million light-years away from Earth exhibited a major increase in activity. It quieted down again by 2020 -- only to dramatically increase its output again in 2023. At that time, it began emitting radio waves at 60 times the previous intensity over just a few months, behavior which has never been monitored in real time for a supermassive black hole. Imaging also clearly shows a pair of oppositely directed plasma jets forming near the black hole and expanding outward over the course of 2023 -- 2024. Читать дальше...
