The universe is a vast infinite thing, and researchers have spent years trying to understand some of its mysteries. Each day we discover something new, and most of the time the news manage to amaze us. The same thing happened recently when a research team from the International Center for Radio Astronomy Research (ICRAR) discovered that all galaxies have something in common.

The researchers discovered that all galaxies move. And things don’t stop there. Every single galaxy, no matter how big or small they are, they all move every billion years. Obviously, the timing is not incredibly precise, but scientists say that it would take the same number of year until the extreme disk of a galaxy rotates all the way around.

The researchers used calculations in order to determine this

In order to reach this results, the team used the average interior density of galaxies for their calculations. You can find the results of their study published in the Monthly Notices of the Royal Astronomical Society.

“This is an important result because knowing where a galaxy ends means we astronomers can limit our observations and not waste time, effort and computer processing power on studying data from beyond that point,” explained Meurer.

Gerhardt Meurer is the lead author of the study and this is not the first time his team analyses galaxies. They also used existing models to help them with their calculations. The study also revealed another interesting details. In the most distant regions of the galaxies, near the edges, there are older stars.

Researchers expected at first to discover younger stars there, but it appears that there are both young and old stars, mixed, as well as interstellar gas. This discovery will definitely help astronomers in the future.
