Dormant Black Hole Awakens After 100 Million Years: Indian Scientists Make Startling Discovery

• A colossal black hole in radio galaxy J1007+3540, dormant for 100 million years, has suddenly reactivated, spewing powerful plasma jets.
• Indian scientists, using the Giant Metrewave Radio Telescope (uGMRT), played a significant role in observing this 'cosmic volcano' eruption.
• The black hole's new jets are battling intense pressure from hot gases in the galaxy cluster, causing them to bend and creating a new structure in space.
• Researchers observed a vast halo of old plasma, indicating the black hole periodically awakens and goes dormant.
• The study, involving uGMRT and LOFAR, provides crucial insights into the life cycle of black holes and their influence on galaxies.
