he being It still keeps many secrets, currently its size is not known with certainty, however Scientific community Little by little progress is being made in the deeper knowledge of how they are formed and how they persist. development.
Recently, A investigation She took on the mission of understanding what happens when a galaxy made up of millions of stars morphs over time.
ASTRO 3D Research Center, in Australiaexplains that Omar Galaxies It is a crucial factor in movement stars that constitute it.
When these suns are younger, they maintain an orderly pattern, but as time passes, the stars inside them begin to move more. chaotic.
The research you publish Monthly Notices of the Royal Astronomical Society It indicates that the tendency of stars to move randomly depends above all on the age of the galaxy, not on its mass or environment.
“If you find a young galaxy it will rotate, whatever environment it is in, if you find one galaxy “The older ones will have more random orbits, whether they are in a dense environment or in a vacuum,” said Scott Crum, a researcher at the International Space Center. Astro 3D.
Another property of young galaxies is that they are star factories, while older galaxies stop star formation.
“We know that age depends on the environment. If a galaxy falls into a dense environment, it will tend to stop star formation. Therefore, Galaxies “Organisms in denser environments are older on average,” said Jesse van de Sande, another member of the research.
he Astro 3D Studio It allows astronomers to rule out many processes when trying to understand its formation Galaxies Thus improving qualitative models being.
What is the oldest galaxy?
the The oldest galaxy in the entire universe He has it by name Sears-93316It is estimated that it is 35 billion light-years away from Earth Land.
Its origin could have occurred only 235 million years after its appearance the great explosionaccording to A study published by the University of Edinburgh And other astronomical institutes Europein April 2023.
This age galaxy They can be found thanks to technology James Webb TelescopeWhich, despite its great ability, was not able to capture the shape or colors of this in a specific way galaxy.
