James Webb Space Telescope Discovers Exciting Ancient Galaxy

New images from NASA’s James Webb Space Telescope (JWST) have revealed that a well-known early galaxy has a shadowy companion that is abundant with star formation.

JWST‘s original target was SPT0418-47, one of the brightest dusty, star-forming galaxies in the early universe. Because it is an extremely distant galaxy—it lies about 12 billion light-years from Earth—its light is bent and magnified by the gravity of another foreground galaxy (located between SPT0418-47 and the space telescope), creating a near-perfect circle called a Einstein call.
