COSMOS-Web unveils JWST's newest gravitational lenses

The JWST era continues to show us the Universe as never before. Its recently completed COSMOS-Web survey provides our deepest wide-field views ever. Revealing a whopping 780,000+ galaxies, some would inevitably be co-aligned with background objects. Massive objects, like foreground galaxies, gravitationally distort any light traveling along their line-of-sight. This leads to the phenomenon of strong gravitational lensing: magnifying, distorting, and creating multiple images of background sources.
