Age is driving changes in the motion of stars in galaxies - study

In a new study, scientists have discovered what exactly is the main factor in the different order in the motion of galactic stars. Previously, scientists considered the influence of the environment or the mass of the galaxy itself. According to the new version based on the study, the tendency of stars to differ in orderly motion is mainly due to the age of the galaxy, UNN reports with reference to Oxford University Press.

Details

Galaxies begin their lives with an orderly rotation of stars, but in some of them the movement of stars is more chaotic. Until now, scientists have not known what causes this - perhaps the environment or the mass of the galaxy itself. The new study, published in MNRAS (Monthly Notices of the Royal Astronomical Society), found that the most important factor shows that the tendency of stars to move chaotically is mostly due to the age of the galaxy - things just get messy over time.

When we ran the analysis, we found that age, regardless of how we break it down, is still the most important parameter

"If you find a young galaxy, it will rotate no matter what environment it is in, and if you find an old galaxy, it will have more random orbits, whether in a dense environment or in a vacuum," the scientific material says.

The research team included scientists from Macquarie University, Swinburne University of Technology, the University of Western Australia, the Australian National University, the University of New South Wales, the University of Cambridge, the University of Queensland, and Yonsei University of the Republic of Korea.

Recall

NASA's Hubble Space Telescope has captured images of the galaxy cluster ESO 185-IG013 in the ultraviolet, visible, and infrared.

The James Webb Space Telescope has revealed detailed images such as the Ring Nebula and the Phantom Galaxy, and has also discovered the most distant black hole known.
