Researchers at the University of Texas at Austin have released photos from the James Webb Space Telescope (JWST) that show for the first time defined images of barred galaxies similar to the Milky Way. The study was published in the scientific journal The Astrophysical Journal Letters.
When we talk about astronomical observations, several variables must be taken into account. Two of them are important: time and visibility.
When we observe the sky, we are looking at the past of the universe, and it makes all the difference in what resolution we look at these phenomena.
Its predecessor, the Hubble Telescope, had already identified several galaxies, but things may change with JWST’s ultra definition right now.
The James Webb telescope is able to produce sharp images with excellent resolution, thanks to its mirrors that capture more light and infrared sensors that can eliminate much of the noise caused by space dust.
New JWST images show rapidly expanding starbar galaxies in a young universe.
Barred galaxies are cradles of stars filled with gas and cosmic dust. They are named according to the shape of the system according to the Hubble Fork classification.
Rods or arms are essential in generating new stars and maintaining the speed of the system. They help by pumping gas and dust into the center of galaxies, accelerating the production of new stars.
Researchers estimate that the observed galaxies date back to the last 11 billion years, when the universe had only 25% of its current expansion.
In addition to being the highest resolution photographs ever taken with a telescope, this is also the oldest known image of the past.
But these data are not just a curiosity of the universe. Observations directly affect how we study the formation of the world.
“This discovery of early rods means that models of galactic evolution now have a new way through rods to accelerate the production of new stars in the early ages,” explains Shardha Jogee, professor of astronomy at the University of Texas.
For researchers, the arms observed in galaxies challenge existing theories.
The work will continue, and scientists now have to test new models to understand how the universe formed and expanded.
