New images from the James Webb Space Telescope show what one of the galaxies could be farthest ever observed.

Images contain objects more than 13,000 million years and they offer a much wider field of view than Webb’s first deep-field image.

These are some of the first images obtained as part of the project. CEERS (English abbreviation for Cosmic Evolution Early Publication Science Survey, survey containing the first scientific results on cosmic evolution). Using the Webb telescope, the collaboration studies how some of the first galaxies formed. At that time, the universe was less than 5% of its current age in a period known as reionization.

Created by 18 assistant researchers from 12 institutions, CEERS also has more than 100 collaborators from ten other countries.

So, in the first week of data analysis, the CEERS team identified a particularly interesting object: a galaxy they named Maisie after the director’s daughter, Steven Finkelstein. This galaxy is only predicted to exist. 300 million years later From Big Bang reports CAB itself in a statement.

The data, which took about 24 hours to collect, comes from a nearby patch of sky. The tail of the Big Dipper. This same area of ​​the sky was previously observed by the Hubble Space Telescope in what is known as the Extended Groth Fringe.

It was a point of light for Hubble

“It’s amazing to see how the point of light for Hubble has now become one of the galaxies for the Webb telescope. more complete and with beautiful structures. Not only that, other galaxies appear out of nowhere!” says Finkelstein, an associate professor at CEERS.

Extremely sharp CEERS images were used to explore distant galaxies. show also many interesting objects and beautifully reveals the complexity of the evolution of galaxies over the lifetime of the universe.

Some galaxies look like graceful windmills, others look like tiny beings at the beginning of their lives, other galaxies show interactions and others are scattered across the sky.

Image obtained by Miri

MIRI is a tool that works in: mid infrared range and that it was developed by a European consortium in which the CAB (CSIC-INTA) participated. It operates at a much higher spatial resolution than previous mid-infrared telescopes.

Compared to NIRcam, MIRI has a smaller field of view but detects longer wavelengths. This, astrophysics community See cosmic dust glowing from star-forming galaxies and black holes over great distances.

“MIRI images are impressive,” says Pérez González, “eight times sharper than anything we’ve ever had.” The CAB (CSIC-INTA) researcher says, “In every major astrophysical mission that begins, the universe surprises us. We always think we’re getting so close to the Big Bang that the galaxies must be very young and we should almost detect the first one. However, JWST reveals to us large galaxies While the universe was only 5% of its current age, it was already highly developed. The universe has been super efficient at forming galaxies for most of its life! Not only that, but complex chemical elements and compounds that should have an impact on the appearance of life.”

The CEERS program consists of more than 60 hours of telescope time, almost half of which has so far been completed. In December the program will be completedadding even more imaging data, along with spectroscopic measurements of hundreds of distant galaxies.
