Homogeneity is something very uncommon in our Universe. The stars and galaxies clump up together at different places owing to the gravitational forces. The astronomers have traditionally found galaxies clusters in the sky an easy object to spot due to the massive brightness and expansion. However, it has been found that the third cluster of galaxy that has till date been untouched in the cosmos.
The galaxy clusters have a very little mass comprised of galaxies itself. The hot gas floating between the galaxies and the dark matter cover the major portion of the Universal mass. The noticeable feature of a galaxy cluster occupies only a smaller portion of the mass. The different characteristics are the reason behind undiscovered galaxy clusters in the Universe. The undiscovered number of clusters has shocked the astronomers. According to Roger Clowes from the University of Central Lancashire, the discovered galaxy clusters could be easily spotted through the captured images of the sky. The galaxy clusters brightness is a plus point when it comes to hunting them but the scientists also thought about looking for less-bright spiral galaxies and irregular galaxies as they are more in number and the distribution of the galaxies in the center are less.
Out of the 191,440 galaxies mentioned in the public data, the researchers added the objects redshift dimension to it so as to understand the object moving in the opposite direction and spot the invisible galaxy clusters. The computational algorithm specially designed for this purpose also aids in finding the clusters of galaxies. As per the current study, there is a third of all galaxy clusters has been hiding until now. Even some new characteristics such as less luminosity and wealthier in spiral galaxies and irregular galaxies of the newly discovered clusters have been revealed along with more of conventional clusters exploration option. Recently, astronomers have captured an unexpected flare of a star being shredded apart by the supermassive black hole present in the heart of a galaxy 290 Million light years away from the Earth. This phenomenon is known as a tidal disruption affair. The first-ever event of the outburst was detected in 2014 by the All-Sky Automated Survey for Supernovae (ASASSN) at optical wavelengths.
