Our Earth is without doubt one of the planets within the photo voltaic system that has the Solar as its host star. And the photo voltaic system resides within the Milky Method galaxy. There are different, smaller galaxies surrounding the Milky Method galaxy. By residing as a satellite tv for pc of the Milky Method. Why is the research of satellite tv for pc galaxies essential? That is as a result of it’ll assist astronomers unravel the mysteries of darkish matter. and to higher perceive the evolution of galaxies over time.
Beforehand, astronomers used normal fashions of darkish matter to foretell the variety of satellite tv for pc galaxies. There are reported to be 220 areas, however research have been carried out during the last a number of years Astronomers discover that the Milky Method galaxy has fewer satellite tv for pc galaxies than normal fashions of darkish matter predicts. giving rise to the time period “The thriller of the lacking servant” and as a way to clear up this thriller a world staff of researchers from Taiwan and the USA, along with astronomers from Tohoku College in Japan, used knowledge from Hyper Suprime-Cam (HSC)-Subaru Strategic Program (SSP) mission to find two new satellites of the Milky Method. . recognized as a dwarf galaxy They had been named Virgo III and Sextans II.
Nevertheless, the HSC-SSP mission sign doesn’t cowl all the Milky Method. A staff of astronomers has calculated that there could also be round 500 satellite tv for pc galaxies. And if it had been doable to specify the variety of satellite tv for pc galaxies extra clearly, photographs and evaluation with a better decision are wanted. The following step is to make use of telescopes with larger magnifications to seize a wider space of the sky, equivalent to these deliberate on the Vera C. Rubin Observatory in Chile subsequent yr within the hope of discovering new galaxies.
