Big moves are being made in the world of science! Behold, faint starlight in the new Hubble images lets astronomers ‘see’ Dark Matter.
According to Discover Magazine, two astronomers have devised a method in order to allow them to “view” dark matter with the light from various rogue stars. The two astronomers have claimed how images of faint starlight taken with the Hubble Space Telescope have been utilized in order to map out dark matters “distribution in galaxy clusters.”
This is the first major move when it comes to mapping out dark matter in space, which can ultimately allow further exploration and aid scientists and astronomers alike to study the nature of dark matter itself. Considering dark matter remains to be quite a mysterious and unknown being of the galaxy, this is a massive step in learning more about it. Not only does dark matter make up nearly 85 percent of all matter in the universe, according to the source, but also it is one of the hardest things to spot in space since it does not absorb, reflect or even emit light.
The high level of obscurity dark matter possesses has even led many to question whether or not it even exists! Although there are theorists who question dark matters very existence, this new method has now allowed astronomers to detect dark matter more easily in galaxy cluster using this technique, which has been called: “intracluster light.” Intracluster light is faint starlight that is “created by interactions between galaxies.”
In this very case, when galaxies interact with one another, their stars can be ripped apart, leaving them to float autonomously through the galaxy cluster, making dark matter slightly more visible. In a recent statement by lead study author Mireia Montes of the University of New South Wales, she said: “these stars have an identical distribution to the dark matter”, and since the intracluster light aligns with the dark matter within these clusters, it allows astronomers to view just how dark matter is dispersed, all by using the Hubble Space Telescope.
This is a huge step in identifying dark matter further and learning more about this very mysterious being.
