James Webb Space Telescope ‘sees triple’ with help from Einstein (photos)

A stunning new image from the James Webb Space Telescope shows a supernova hosting galaxy not once, not twice, but three times at different points in time.

This seemingly time-defying image by the James Webb Space Telescope (JWST) was possible thanks to the massive gravitational influence of a foreground galactic cluster and a light-bending phenomenon predicted by Albert Einstein over a century ago called “gravitational lensing.”

In his theory of general relativity, Einstein predicted that mass warps the very fabric of space and time, or “spacetime.” This is analogous to placing a ball on a stretched rubber sheet, with the ball causing a dent in the sheet. The greater the mass of the ball the larger the degree of warping it causes. This is also true in the case of spacetime, stars cause a greater “warp” than planets, and galaxies cause a greater warping of space than stars.
