Biggest explosion ever seen spotted in space – and scientists don’t know what it is
The biggest explosion ever seen has been spotted in space – and scientists don’t know for sure where it came from. The blast was brighter than almost anything ever seen and has been going on for years, making it by far the most powerful such event witnessed by scientists. It has been ongoing for more than three years, and took place nearly 8 billion years away. Astronomers have proposed a host of possible explanations for the blast: it may be a vast cloud of gas that was torn apart by a black hole, for instance. But nothing on such a scale has ever been seen before and the explosion may have come from something else entirely. It is more than 10 times brighter than any known supernova and three times brighter than the brightest tidal disruption event, where a star falls into a supermassive black hole. The explosion, known as AT2021lwx, took place when the universe was around six billion years old, and is still being detected by a network of telescopes. The astronomers, led by the University of Southampton, believe the explosion is a result of a vast cloud of gas, possibly thousands of times larger than our sun, that has been violently disrupted by a supermassive black hole. Fragments of the cloud would be swallowed up, sending shockwaves through its remnants, as well as into a large dusty “doughnut” surrounding the black hole. Such events are very rare and nothing on this scale has been witnessed before, the researchers say. Last year, astronomers witnessed the brightest explosion on record – a gamma-ray burst known as GRB 221009A. Although this was brighter than AT2021lwx, it lasted for just a fraction of the time, meaning the overall energy released by the AT2021lwx explosion was far greater. AT2021lwx was first detected in 2020 by the Zwicky Transient Facility in California, and subsequently picked up by the Asteroid Terrestrial-impact Last Alert System (ATLAS) based in Hawaii. But until now the scale of the explosion had been unknown. Dr Philip Wiseman, research fellow at the University of Southampton, who led the research, said: “We came upon this by chance, as it was flagged by our search algorithm when we were searching for a type of supernova. “Most supernovae and tidal disruption events only last for a couple of months before fading away. For something to be bright for two plus years was immediately very unusual.” The Southampton-led team believe the most feasible explanation for what caused the explosion is an extremely large cloud of gas (mostly hydrogen) or dust that has come off course from its orbit around the black hole and been sent flying in. Dr Wiseman added: “With new facilities, like the Vera Rubin Observatory’s Legacy Survey of Space and Time, coming online in the next few years, we are hoping to discover more events like this and learn more about them. “It could be that these events, although extremely rare, are so energetic that they are key processes to how the centres of galaxies change over time.” The findings are published in Monthly Notices of the Royal Astronomical Society.
