Have you ever wondered about the number?Stars Is on
The universe ? It is impossible to count them accurately. But according to
Astronomer Brian Jackson of Boise State University
United StatesHowever, their number and reports can be estimated Conversation, Sent by எண்மராமா This Thursday.
“Look at the clear night sky, you’ll see thousands of stars, about 6,000. But that’s only a small part of the stars. Others are so far away that we can not see them,” the scientist said. According to him, there will be 200,000,000,000,000,000,000,000,000,000 in our universe. That’s a lot of zeros, so we’ll help you: it’s 200 trillion stars or 200,000 trillion.
The universe is 14 billion years old
To achieve such a number, astronomers must first count the number of galaxies in the universe. A calculation possible thanks to the most detailed photos of parts of the sky. Experts say, “Count all the galaxies they see in these photos. This number is multiplied by the number of photos needed to photograph the entire sky.” There are 2,000,000,000,000 or two trillion galaxies in our universe. , Because they are often far away.
So astronomers are based on the number of stars in our galaxy: the Milky Way. Estimated number 100,000,000,000,000 stars, or 100 billion. By multiplying two digits, scientists estimate the number of stars in the universe: 100,000,000,000 x 2,000,000,000,000 = 200,000,000,000,000,000,000,000,000. “The number is huge, hard to imagine, but try it: it’s ten times the number of glasses of water in all the Earth’s oceans.”
