An MIT-led team of scientists has developed a new algorithm – named the CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) — that could help astrophysicists take the first-ever image of a black hole. An artist’s impression of the disc of material around Sagittarius A*. Image credit: L. Calçada / ESO. CHIRP would stitch together data collected from the Event Horizon Telescope (EHT), an array of telescopes spread out...

An artist’s rendition of the Akira (right) and Tetsuo (left) galaxies in action. Akira’s gravity pulls Tetsuo’s gas into its central supermassive black hole, fueling winds that have the power to heat Akira’s gas. Because of the action of the black hole winds, Tetsuo’s donated gas is rendered inert, preventing a new cycle of star formation in the Akira galaxy. Image credit: Kavli IPMU.
