“It should never exist, the James Webb Telescope captured an extra-galaxy”

Astronomers have discovered it a galaxy wind and star shape, which appears in the images of the Space Telescope James Webb and that was not the main objective of observation. Galaxies are united by gravity and are formed by stars and planets, with enormous clouds of dust and gas, including dark matter. The pineapple galaxies are the most abundant in the universe and, by definition, they are small and low in brightness.

You have less than 100 million stars, for that matter the Via LácteaFor example, it holds 200 million million stars. Recent observations of pineapple galaxies regarding the abundance of “galaxias ultradifusas“More to the occasion of great espectroscopic studies, previous suggestions suggest that our understanding of the population of galaxies pineapple may be incomplete.

They said with this galaxy that “it should not” exist by chance

In the new study, a team led by Arizona State University assistant scientific investigator Tim Carleton was initially observing a cluster of galaxies as part of the project JWST Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS).

The galaxy Enana, PEARLSDG, appeared in some of the JWST images of the team. It was not the absolute objective, only a little removed from the main observation field, in the area of ​​the space where there is no hope for anything. These results have been published in the Astrophysical Journal Letters. PEARLSDG did not have the usual characteristics of a nanogalaxy that one would hope to see. It doesn’t interact with a nearby galaxy, but it also forms new stars. It turns out that this is an interesting case of an inactive galaxy in the sky.

This type of galaxies Isolated and inactive pineapples have not been seen before, except in relatively few cases. In reality, no one expects that they exist, our current understanding of the evolution of galaxies, so that what we see this object helps us to improve our theories above the formation of galaxies“, I said Carleton in a press release. “In general, the pineapple galaxies that exist alone continue to form new stars”, added.

This galaxy captured by James Webb contains important information

Here’s to the understanding of astronomers above evolution of galaxies he showed an airy galaxy that would continue to form young stars or interact with a larger companion galaxy. This theory does not apply to PEARLSDG, which presents itself as an ancient historical population, which does not form new stars and is kept confidential.

As an additional surprise, you can observe individual pieces the JWST images of the team. These stars are brightest in the longitudes of the JWST wave; It is one of the most beautiful galaxies in which we can see these stars with this level of detail. The shine of these stars allows astronomers to meditate on the distance: 98 million years of light.

For this study, Carleton and the team used images from the JWST infrared camera (NIRCam); espectroscopic data from the DeVeny optical espectrographer at the Lowell Discovery Telescope in Flagstaff, Arizona; archive images of the telescopes NASA Galex and Spitzer spaces; and terrestrial images from the Sloan Digital Sky Survey and the Dark Energy Camera Legacy Survey.
