Astronomers have spotted the wreckage left by a massive collision between two huge icy planets around a distant, sunlike star.
"An astronomer on social media pointed out that the star brightened up in the infrared over a thousand days before the optical fading. I knew then this was an unusual event," Matthew Kenworthy, study co-lead and a researcher at Leiden University, said in a statement."To be honest, this observation was a complete surprise to me."
The team found that the collision of two ice giants likely caused the system to double in brightness at infrared wavelengths three years before ASASSN-21qj started to fade in visible light.
