Hundreds of distant galaxies seen through the James Webb . telescope

An image just captured by the James Webb telescope's Delicate Guide Sensor provides a fascinating view of distant galaxies in the universe in infrared light. It shows a number of stars and hundreds of galaxies scattered across the distant universe.

This image, released by NASA on July 6, was taken by the James Webb Space Telescope over an eight-day period in May and consists of 72 snapshots taken over 32 hours of exposure.

As such, the most powerful and expensive space observatory ever built has finally begun its ambitious scientific work in earnest.

While the near-infrared camera of the James Webb telescope focuses on a star called HD147980. During the test, the FGS kept the telescope pointed at its target. The resulting image, a by-product of this supporting work, shows the universe on a white to red color scale, with whiter shades representing the brightest infrared-emitting objects and the redder shows dimmer objects.

"The faintest blobs in this image are exactly the kind of faint galaxies the telescope has," said Jane Rigby, James Webb telescope control scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland. James Webb will do research in the first year of scientific activities'.

The mission of this instrument is to enable precise measurements by other instruments by helping the telescope to precisely point at the stars and galaxies of interest to scientists. However, the images hint at groundbreaking discoveries coming from the observatory.

"I was thrilled to see all the detailed structure in these faint galaxies," said Neil Rowlands, FGS program scientist at Honeywell Aerospace, which built the instrument.

While the image may be the deepest image of the universe in infrared light the public has ever seen, its glory won't last long, according to Bill Nelson, NASA Administrator.

The James Webb telescope carries two cameras and two spectrometers and is specifically designed to see infrared light in order to detect some of the most distant (and oldest) galaxies in the universe.

Although these galaxies emit visible light, due to the redshift effect caused by the expansion of the universe, this visible light shifts to longer infrared wavelengths, requiring a telescope. super cold like Webb.
