Gravitational lenses

The galaxy cluster SMACS 0723 - the first scientific photograph by the James Webb Space Telescope. This cluster acts as a gravitational lens and increases the light of distant galaxies, including those from the early universe. Photo: NASA, ESA, CSA, and STScI

The galaxy cluster RXCJ0600-2007 imaged by the NASA/ESA Hubble Space Telescope, combined with gravitational lensing images of the distant galaxy RXCJ0600-z6, 12.4 billion light-years away, observed by ALMA (shown in red). Due to the gravitational lensing effect of the galaxy cluster, the image of RXCJ0600-z6 has been intensified and magnified, appearing to be divided into three or more parts.

The galaxy cluster has so much mass that it acts as a gravitational lens, causing light from more distant galaxies to bend around it. These distortions may appear in many different forms, such as long lines or arcs.

"This diagram explains how the light from the distant galaxy is disrupted by the gravitational influence of a nearby galaxy that is in the way, acting like a lens and making the distant object appear blurry but bright. This process creates rings of light known as Einstein rings. Analysis of the disruption has revealed some of the star-producing galaxies At a great rate and brightness in the light of 40 trillion suns and it has been magnified by gravitational lensing up to 22 times.
