Images from the James Webb Space Telescope continue to surprise the world of science. This time it is about two galaxies, none of which have been recorded, and they are the second and fourth farthest galaxies from Earth that have been recorded so far.

In an article published in The Astrophysical Journal Letters, researchers from Pennsylvania State University reported the results by observing images of James Webb.

Thanks to infrared image-generating technology, James Webb has the ability to show science parts of the universe that were not seen or distorted by other instruments used in the past, such as Hubble.

By taking advantage of this precision, researchers can confirm the existence of these two distant galaxies. Furthermore, through calculations that take into account light emitted from the electromagnetic spectrum, they estimated the distance at which both galaxies are located.

“Detailed modeling of star clusters using data from JWST NIRCam and NIRSpec (two science instruments aboard James Webb) confirms the primitive properties of these galaxies: low mass, young, rapidly accumulating, poor in metals and star formation,” the researchers explained.

Both galaxies have a radius of ultraviolet radiation emitted by their star, which according to the study is larger than other systems recorded in the past using these same instruments.

These investigations are working to understand some of the details behind the formation of the oldest galaxies that would explain their evolution.
