Deep observations from the James Webb Space Telescope (JWST) have revealed an exceptionally large galaxy in the early universe. It’s a cosmic giant whose light has travelled over 12 billion years to reach us. We’ve dubbed it the Big Wheel, with our findings published today in Nature Astronomy.

The "Cosmic Horseshoe" is an Einstein ring, a system made up of a foreground galaxy whose mass is so great, it warps the light from a galaxy behind it. Now, astronomers know where it gets this mass from.

Einstein predicted the existence of gravitationally-warped rings of light in 1915. Now, a new one has been discovered just a cosmic stone's throw from our own planet.
