Story summary

The James Webb Space Telescope (JWST) captured a collage of eight galaxies showing gravitational lensing, with JWST providing detail greater than the Hubble Space Telescope.
Gravitational lensing, predicted by Einstein's general relativity, enables astronomers to study galaxy formation across cosmic time.
The COSMOS-Web program, including the COSMOS-WEB Lens Survey (COWLS), identified over 400 lensing candidates from more than 42,000 objects examined.
