Cosmic Shockwaves: “Extreme Nuclear Transients” Outshine Every Known Explosion Since the Big Bang
Stunning new cosmic explosions called ENTs shatter energy records, offering a rare window into the universe’s deepest secrets.
- 25x brighter than any supernova previously observed
- 100 Suns – energy radiated by ENTs during their luminous flare
- Years – how long ENTs outshine their entire host galaxies
- 3 detected in 2016, 2018, and 2020 using global observatories
Brace yourself: astronomers have just identified a colossal new kind of cosmic explosion that dwarfs even the most powerful supernovae in history. These events, known as Extreme Nuclear Transients (ENTs), throw off enough energy to outshine entire galaxies – and could unlock mysteries about how the universe’s largest black holes grow.
Using data from NASA, the European Space Agency (ESA), and observatories across the planet, a University of Hawaiʻi team discovered these record-shattering flares lurking deep in galactic cores. ENTs are now confirmed as the mightiest cosmic blasts since the Big Bang itself.
What Exactly Are Extreme Nuclear Transients?
ENTs are rare, apocalyptic events triggered in the heart of distant galaxies. Unlike regular supernovae — which mark the spectacular death of massive stars — or the previously known tidal disruption events (TDEs) that occur when a black hole rips apart a star, ENTs turn all previous records upside down.
The first clues struck in 2016 and 2018 via the ESA‘s Gaia mission: two unusual, blazing flares that lingered for years. Digging into telescope archives, astronomers found a third even brighter burst in 2020. One of them, Gaia18cdj, outshined the brightest supernova ever recorded — by a staggering factor of 25.

How Do ENTs Happen?
At the center of every massive galaxy lurks a supermassive black hole. Occasionally, a star drifts too close and is torn apart by titanic tides — but in an ENT, the star is gigantic, 3-10 times the Sun’s mass. The resulting cosmic maelstrom hurls stellar debris into orbit, igniting a prolonged eruption brighter than 100 Suns combined.
ENTs last much longer than typical supernovae, lighting up the universe for years, not just weeks. For a brief cosmic instant, they blaze brighter than every other star in their galaxy.
Why Do ENTs Matter? Astronomers Look Back in Time
ENTs give scientists precious tools for peering deep into space — and thus back in time. Their almost unmatched brilliance lets astronomers observe black holes and intense star formation in galaxies as they existed billions of years ago. These events happen when the universe was half its current age, during a period when galaxies formed stars and fueled their central black holes far more vigorously than today.
Understanding ENTs may unlock secrets behind how supermassive black holes at galactic centers grow and change, transforming their host galaxies in the process. As astronomers hunt for more of these rare titans, the very fabric of the cosmos comes into focus like never before.
Q&A: The New Frontier in Black Hole Science
Q: How are ENTs different from supernovae?
ENTs are at least 10 times brighter and last for years, while supernovae fade after weeks. Their energy output dwarfs almost any other cosmic event.
Q: What causes these cosmic explosions?
Astronomers believe ENTs erupt when a massive star is shredded by a supermassive black hole, releasing an unimaginable flood of energy as gas swirls into the abyss.
Q: Could we see one in our galaxy?
ENTs are extremely rare, with only three found so far. But their discovery means astronomers all over the world will be watching, searching for the next big bang.
