The James Webb Space Telescope has captured a remarkable new image of the galaxy cluster Abell S1063. This cluster is located about 4.5 billion light-years from Earth in the constellation Grus. Abell S1063 acts as a cosmic lens.
Its immense mass bends and warps light from galaxies far behind it. This effect is called gravitational lensing. It makes the light from these distant galaxies brighter and more visible.
One benefit of this lensing is seen in the recently discovered galaxy MoM-z14. This galaxy formed just 280 million years after the Big Bang. By studying the light bending around Abell S1063, astronomers can learn about these ancient, faint galaxies that would otherwise be impossible to observe.
Webb reveals MoM-z14 through lensing
The new image from Webb is a “deep field” capture. It is made up of nine different exposures taken using Webb’s NIRCam instrument.
The total exposure time is around 120 hours. This deep field image is Webb’s most distant look at a single target so far. It is also one of its most spectacular.
The light in this image has been traveling through space for billions of years. Some of the galaxies captured have never been observed before. This achievement shows the power and precision of the James Webb Space Telescope.
It cements Webb’s role as a critical tool in our quest to understand the cosmos.
