Gravitational lens COSJ100025+015245
Somewhat resembling a ringed planet at first glance, this lens is markedly different from the others presented in the Picture of the Month compilation of gravitational lenses from the COSMOS-Web survey. This shows a rare case in which the lensing galaxy is a thin disc galaxy rather than a giant elliptical galaxy. The dust within the disc absorbs the source’s light, providing a valuable opportunity to study dust in very distant galaxies.
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. The lensing galaxy appears in the centre of the frame as a thin disc, with small glowing arcs above and below its centre.]
