Cosmic Volcano: Black Hole Erupts After 100M Years

Midnapore, India – Astronomers have captured a stunning view of a supermassive black hole in the galaxy J1007+3540 dramatically reawakening after an estimated 100 million years of dormancy, erupting like a “cosmic volcano” and blasting fresh jets of magnetized plasma across nearly one million light-years of space. This remarkable event, providing one of the clearest views yet of a “reborn” black hole, was reported by the Royal Astronomical Society, Popular Science, ZME Science, Universe Today, Space.com, and ScienceDaily. Each of the bullet points immediately below have been confirmed by at least four of the six respected sources we curated on this story.

• Astronomers have observed a supermassive black hole in the galaxy J1007+3540 erupting like a “cosmic volcano”.
• The black hole had been dormant for approximately 100 million years before its reawakening.
• It is blasting out fresh jets of magnetized plasma that stretch across nearly one million light-years of space.
• Observations were made using highly sensitive radio interferometers, specifically the Low Frequency Array (LOFAR) in the Netherlands and India’s upgraded Giant Metrewave Radio Telescope (uGMRT).
• The galaxy J1007+3540 resides within a massive galaxy cluster, and the intense external pressure from the hot gas in this environment bends, compresses, and distorts the newly launched jets.
• The observations reveal a bright, compact inner jet surrounded by a broader cocoon of older, dimmer plasma from previous eruptions, indicating episodic activity where the black hole’s central engine repeatedly turns on and off.

Additional Details Reported

Lead researcher Shobha Kumari of Midnapore City College, India, noted that this dramatic layering of young jets inside older lobes is a signature of an episodic active galactic nucleus. The research highlights the messy, chaotic struggle between the erupting black hole and the crushing pressure of its surrounding galaxy cluster.
