Astronomers release mosaic of galaxies seen by James Webb | Sciences

The mosaic, made by the “Cosmic Evolution Early Release Science Survey (CEERS)” group, is a combination of four images taken by James Webb. The original file, in high definition, is about 360 MB and can be downloaded in this link. The medium resolution image is at the top of the report.

The group highlighted six points on the mosaic and explained what each one offered. see below:

On the social network Twitter, astrophysics PhD student Rebecca Larson, part of CEERS, explained Image 1, which looks like a blue ball: “These clusters are little pockets of stars forming!”

Point 2 was an image of a galaxy compared to a game of “Pacman” by scientists: a random alignment of a bright galaxy with several small galaxies veering across the sky.

Point 3, “Space Kraken” – an interactive system of galaxies – 9 billion light-years from Earth:

Larson described Image 4 as a “chaos” – a group of interacting galaxies that also hosts the first possible discovery of a supernova (star explosion) by James Webb.

In Image 5, Larson highlights the level of detail of galaxies that James Webb has been able to capture:

“I had a really hard time choosing specific galaxies to view, but I kept coming back to this spiral because of the huge amount of detail we capture with James Webb in galaxies so far away,” said the astrophysicist. Galaxy in the picture About 6.4 billion light-years away.

In Photo 6, Larson told a joke: “I tried to call this look ‘The Great Space Confusion’, but the reporters said ‘No’.”

The CEERS group explained that the image shows a random alignment of a galaxy with a tidal tail – the result of the gravitational interaction between two galaxies – and a group of red galaxies.
