World Premiere: Light Coming From Rogue Stars Has Been Studied

We all know that stars are fascinating cosmic objects. Some of them are so rebellious that they don’t even want to remain bonded by their host galaxies, so they go rogue and wander around within the intergalactic realm. Astronomers couldn’t manage to study the light coming from rogue stars, but that soon changed due to new observations.

According to the new study that appears in the journal Monthly Notices of the Royal Astronomical Society, a new technique was used by astronomers to analyze, for the first time, light belonging to rogue stars.

An eye-opening study

It seems that the new research in question can provide a lot of help to astronomers. Here’s what Cristina Martínez-Lombilla has to say, a scientist from the University of South Wales:

We know almost nothing about intra-group light,

Unveiling the quantity and origin of the intra-group light provides a fossil record of all the interactions a group of galaxies has undergone and provides a holistic view of the system’s interaction history.

The astronomers’ mission was nothing but easy. The same scientist explains that the intra-group light’s brightest parts are dozens of times fainter compared to the darkest night sky that we can see from Earth. She also explains how astronomers managed to detect the light:

We have developed a tailored image treatment procedure that allows us to analyze the faintest structures in the universe. It follows the standard steps for the study of faint structures in astronomical images  —  which implies 2D modeling and the removal of all light except that coming from the intra-group light.

The new study could even grant astronomers a lot of help in the understanding of cosmic evolution. In their research, they’ve also spotted a few galaxies located billions of light-years away into space. It’s well-knownn in astronomy that the farther you look into the Universe, the more you look back in time.

Even since he was a child, Cristian was staring curiously at the stars, wondering about the Universe and our place in it. Today he's seeing his dream come true by writing about the latest news in astronomy. Cristian is also glad to be covering health and other science topics, having significant experience in writing about such fields.
