The dark matter present in the universe contributes more than 80 percent of the matter in the universe. This mysterious majority has been studied recently by a group of astronomers with the help of data collected from NASA's Chandra X-Ray Observatory.

According to Phys.org, astronomers have recently studied the properties of the mysterious dark matter present in the universe. A total of 13 galaxy clusters is involved in the study with the help of which, scientists have explored that the dark matter in the universe might not be cold, but fuzzy.

For quite a few years, cosmologists have been studying the dark matter in space. In spite of the fact that it can't be watched straightforwardly, dark matter interacts by means of gravity with typical, radiating matter (that is, anything comprised of protons, neutrons, and electrons packed into atoms). Profiting by this theory, astronomers have now studied the effects of dark matter utilizing an assortment of methods, including perceptions of the movement of stars in galaxies, the movement of galaxies in galaxy clusters, and the dispersion of X-ray radiating hot gas in galaxy clusters.

From decades, astronomers were struggling hard to study the dark matter in detail such as what it is made of or what are the properties of dark matter. NASA's Chandra X-Ray Observatory reported that the previous known model on dark matter reveals that dark matter is a more massive particle if compared to a proton, which is cold.

This also means that dark matter moves at a speed which is very much smaller than the speed of light if compared. But the model had problems in explaining the distribution of matter on smaller scales of galaxies.

The recent model studied by the astronomers on the dark matter has successfully explained the distribution of dark matter in smaller galaxies. A group of researchers utilized Chandra perceptions of the hot gas in 13 galaxy clusters to check whether the fuzzy dark matter model works at bigger scales as compared to galaxies.
