This is Icarus. The farthest away single star we've ever seen. It's a blue supergiant star, not a supernova or gamma ray burst or anything, just a star, seen from 9 𝘣𝘪𝘭𝘭𝘪𝘰𝘯 light years away.

We were only able to see it for a time because it was Gravitationally Lensed by passing directly behind another star and then magnified further by other galaxy clusters and dark matter. Spacetime acted like a telescope for this single star, magnifying about 2000 times.

Due to the speed of light and short lived nature of blue supergiant stars, Icarus is likely dead by now, replaced by a black hole. Its light has traveled a long 9 billion year journey just to get here when it was originally emitted by Icarus so long ago.

@starwall gravitational lensing is one of the coolest things in nature
