Ottawa, June 2, 2016, 09:56 – REGNUM Canadian astrophysicists have published precise estimates of the mass of the Milky Way, including the weight of dark matter, according to The Guardian referring to the Astrophysical Journal.
According to their estimates, the mass of our galaxy the sun is greater than the mass of 700 billion times. It is worth noting that 88% of this mass is invisible and imperceptible dark matter.
Scientists Earth better know the mass of distant galaxies, since the calculation of their weight easier to produce, watching from the sidelines. Estimates of the mass of the Milky Way’s difficult, because we observe this galaxy from the inside. In addition, we do not see the stars, located on the opposite edge of the galaxy as they closed us accumulations of dust and gas located in the center of the Milky Way.
The calculation of Canadian astrophysicists based on the method of compensating the incomplete observations averaging speeds the rotation of stars in a number of neighboring clusters. According to calculations made by this method, the mass of the Milky Way galaxy was less than expected – not trillion solar masses, as previously thought, and about 700 mass of the Sun.
Scientists believe that their study and calculations to help calculate accurate. the mass of a supermassive black hole at the center of our galaxy, and clarify our understanding of the development and growth of the Milky Way.
