In this case, filaments radiate away from a “zombie star” the explosion created. Then, in 2023, astronomers spied weird filaments glowing with light from sulfur within the nebula. Scientists know the supernova created the filaments, but it’s unclear how or when the structures formed. The robust data that the instrument captured allowed the team to measure the motions of each filament and create a 3D map. The Keck Cosmic Web Imager enabled measurements of the velocity of any material within the nebula that emits light.
