What is the biggest star in the universe 2021

According to an estimate, there may be 200000 crore galaxies in the official observable universe, only our Milky Way Galaxy itself is estimated to start 40000 crores, while we have 1 medium sized Galaxy C and a thousand times bigger than that Galaxy is present in this universe Famous astrologer Coles Sagan had said that there are not so many stars in this universe than the earth is not a grain of sand on the seashore, somewhere they study and estimate that there is a quadrillion in this universe, even humans are not yet capable enough to have their own solar system. Go beyond and our face is only a small star out of the countless stars of this universe

After all, which is the biggest star in the universe?

Talking about the largest date of the universe, earlier the names of UY scuti and VY canis majoris were at the top, but in 2021 we have discovered the largest date of the universe, named Stephenson 2-18 After this discovery, UY scuti went so far behind Now it does not even figure in the list of the 10 most studied stars in the universe.

Before Stephenson 2-18, we considered the largest star of UY scuti. It is located in the scutum constellation. It is believed that this star is located 2500 light years away from Earth and its circumference has increased by 1708 times that of the sun. In the year 2012 by the Very Large Telescope in the Atacama Desert of Chile, amber interferometry technique was used for this, and when the UY scuti was calculated, this technique included the star and the distance from where it is being measured. It is very important and if there is a slight change in it, then there is a big difference in its calculation, that is why when UY scuti was measured again, it turned out to be 700 times bigger than Surat and that is why it is no longer the biggest star. It is said and due to this wrong calculation, we used to consider UY scuti as the biggest star in the universe.

Know about the universe's largest star Stephenson 2-18

This star is 20000 light years away from Earth. Stephenson 2-18 is present in the open cluster Stephenson 2-18 is located in our Milky Way itself and it was discovered in the year 1990 during the Charless Bruce Stephenson Deep Intra Survey Stephenson 2-18 his cluster It is the largest of the stars, if we compare its size with our appearance, then it has increased 2150 times more than our appearance and if we keep the place of the sun in our solar system on this date, then it will relax Mercury and Venus. Will handle it inside itself and if we talk about it, then it is only around 1.4 to 20 million now and it is so big from now on and according to scientists when there will be a supernova expression about it then it will be very dangerous and scientists have this. It is also believed that this supernova explosion can also give rise to a black hole and life is not possible around this date because it is not yet old enough that life can be possible around this date like Earth.

Which is the second largest star in the universe

The second largest star in the universe is MY Cephei and it is 9000 light years away from Earth and it is located in the NGC 7419 open cluster and MY Cephei is 2061 times bigger than our Sun and this star is much larger than other stars. It's too cold that's why it's not so shiny.

Which is the third largest star in the universe

Which is the fourth largest star in the universe

The fourth largest star in the universe is the RX telescope and its brightness varies from time to time and it is about 19000 light years away from Earth and it is 1858 times more magnified than our sun.
