The Hubble Space Telescope shocked astronomers when it discovered Earendel, a star so old, it existed perhaps just 1 billion years after the big bang. Now the experts have used the James Webb Space Telescope, Hubble's powerful infrared partner, to take a gander, and its first look has revealed even more details about the star. To scientists' surprise, Earendel might actually have a cooler, redder space companion: another star. Because the expansion of the universe has stretched the other lightsource to wavelengths longer than Hubble can sense, only Webb could find those clues. "Astronomers did not expect Webb to reveal any companions of Earendel since they would be so close together and indistinguishable in the sky," according to the Space Telescope Science Institute in Baltimore.

The James Webb Space Telescope, a collaboration of NASA, the European Space Agency, and the Canadian Space Agency, captured three copies of the same distant galaxy cluster mid supernova through the quirky natural phenomenon of gravitational lensing.
