According to scientists from China and other countries, there is much less gravitational dark matter in the Milky Way, which could affect the mass of our galaxy.
A group of Chinese and international scientists have calculated the mass of the Milky Waywhat do you estimate about 550,000 million times greater than that of the Sun, picks up today the state agency Xinhua.
The data revealed by the investigation This is half the estimate from other previous studies.which placed the mass of our galaxy at approximately one trillion times greater than that of the Sun, reports the agency’s dispatch.
The mass of the Sun is a standard unit in astronomy. and is frequently used to indicate the mass of other celestial bodies.
The research was recently published by the scientific bulletin Monthly Notices of the Royal Astronomical Society of London.

Milky Way “light”
“Our calculations suggest that the Milky Way is lighter than previously thought”explains Xue Xiangxiang, a member of the scientific team, who added that the finding means that “there is much less gravitational dark matter” in the galaxy that hosts our solar system.
According to Xue, although the mass of the Milky Way is “key” to understanding the dynamics of our galaxy, there has been great “uncertainty” in its calculation due to “limited observations”.
The scientists relied on data collected by the Chinese LAMOST telescope and the Gaia satellite of the European Space Agency.
