Question
In which year was the James Webb Space Telescope (JWST)
launched?Solution
Webb telescope makes stunning observation of Milky Way’s giant black hole Black hole: Sagittarius A* (Sgr A*) – located at the centre of our galaxy. Telescope: James Webb Space Telescope (JWST), launched in 2021 and data collection to begin in 2022. Discovery: Movement and glowing light observed in the accretion disk of gas around the black hole. 1-3 large and several small flares were observed in 24 hours. The effect of gas colliding and compression in the magnetic field around the black hole.
