Cosmic Volcano Awakens: Black Hole Explodes Back to Life After 100 Million Years

• Astronomers report a supermassive black hole in galaxy J1007+3540 has reignited after 100 million years of dormancy.
• The restarted black hole is producing episodic jets that stretch nearly one million light-years, shaping galaxies.
• Images from Low Frequency Array and Giant Metrewave Radio Telescope captured the renewed jet emission and older plasma material.
• The galaxy resides in a dense cluster, where intense external pressure bends and compresses the outward-pushing jets.
• This discovery provides insights into galaxy evolution, showing repeated black hole restarts and jet-gas interactions.
