Gravitational lens COSJ100018+022138

Previously confirmed using data from the NASA/ESA Hubble Space Telescope, this lens is revealed in greater detail by Webb. The elliptical lensing galaxy is seen as it was when the Universe was about 4 billion years old. The blue galaxy whose light has been warped into a circle goes back even further, shown as it was when the Universe was less than 2 billion years old.

This gravitational lens is one of eight featured in the September 2025 Picture of the Month.

[Image Description: This image shows a deep galaxy field as seen by Webb, with a distinct gravitational lens at the centre. A central elliptical galaxy in the foreground has a distorted background galaxy surrounding it as a small, bright blue, circular shape.]
