The term "AT2017" typically refers to AT2017gka, which is a unique astronomical event. It was a supernova, or explosion of a massive star, observed in 2017 in the constellation Perseus. What made AT2017gka especially notable was the discovery that it was accompanied by a kilonova, a catastrophic collision of two neutron stars or a neutron star and a black hole. This event also coincided with a gamma-ray burst, making it one of the most extreme cosmic phenomena known. The discovery provided key insights into the life cycles of massive stars and the production of heavy elements in the universe.
