‘Biggest Booms Since The Big Bang’ Found As Black Holes Shred Stars
- Researchers from the Institute for Astronomy in Hawaii announced on June 4, 2025, the identification of extreme nuclear transients , the most powerful cosmic explosions observed so far.
- These ENTs occur when massive stars, at least three times the sun's mass, stray too close to supermassive black holes and are torn apart, releasing immense energy.
- ENTs surpass the energy output of the brightest supernovae, remain luminous for years, and have been detected by ESA's Gaia spacecraft and the Zwicky Transient Facility as long-lived flares.
- An extreme nuclear transient called Gaia18cdj unleashed energy exceeding that of the most powerful supernovae by a factor of 25, surpassing the combined lifetime energy output of 100 suns.
- These results shed light on how supermassive black holes developed when the cosmos was approximately halfway to its present age and introduce a new approach for exploring galaxy formation and the evolution of these massive objects.

Astronomers Identify 'Extreme Nuclear Transients' 100 Times More Energetic than Supernovae
Astronomers have revealed the detection of extreme nuclear transients (ENT), a newly identified class of cosmic events that represent the most energetic explosions ever observed. Researchers at the University of Hawaii’s Institute for Astronomy (IfA) made the explosive discovery, witnessing enormous stars, each with masses at least three times that of the Sun, straying too close to the destructive pull of supermassive black holes. The result is…
Astronomers detect most powerful explosions since Big Bang
At any given time across the universe, massive cosmic bodies are releasing incomprehensible amounts of energy. Stars burn like celestial nuclear fusion reactors, quasars emit thousands of times the luminosity of the Milky Way galaxy, and asteroids slam into planets. But all of these pale in comparison to a new class of events discovered by researchers at the University of Hawai’i’s Institute for Astronomy (IfA). According to their findings publi…
