Important facts about the Milky Way galaxy. Know its weight and number of stars

science and technology

The Milky Way galaxy is the largest place in our small planet, yet we do not know much about this starry galaxy with a large black hole. We are monitoring a number of these important information, according to the scientific website "Livescience."

Although astronomers are not exactly sure of the weight of our galaxy, estimates range from 700 billion to 2 trillion times the mass of the sun. Perhaps this confusion is due to the fact that most of the mass of the galaxy, 85% of which is dark matter, perhaps The latest update to estimate the Milky Way block reached 960 billion times the mass of the Sun.

Just as there is no specific weight of the galaxy, there are no specific statistics on the basic number of stars. Telescopes are only the brightest stars in the galaxy, many of which are hidden by blocking the gas and dust.

But the numbers are approximate. The European Space Agency's Gaia satellite made a map of 1 billion stars in our galaxy, and scientists believe that this represents 1 percent of the total, so the Milky Way may contain about 100 billion stars.

The sad truth about our galaxy is that scientists have observed an expected collision between the Milky Way galaxy and the neighboring galaxy "Andromeda" because of their movement, but the bright side is that it takes 4 billion years.
