Which star is the brightest star on a winter night?

LBV1806-20, the brightest star ever observed in the universe, may be as bright as seven times as bright as the current record holder for star brightness. In their report to the National Conference of the American Astronomical Society, the astronomers who discovered the star said that the star on the other side of the Milky Way is 10,000 light-years away from us, so despite its brightness, we still can't see it in the night sky, but only with the help of infrared meters. According to the researchers, the star surpasses the current brightness record holder "Pistol Star".

Pistol Star got its name from the surrounding nebula shaped like a pistol. Pistol stars are 5 million to 6 million times brighter than the Sun, while LBV1806-20 may be 40 million times brighter than the Sun. Astronomers have known sporadically about LBV1806-20 since the 90s of the 20th century.

At the time, they identified it as a "high-luminosity blue variable star", a relatively rare, large, short-lived star. Researchers believe that LBV1806-20 is at least 150 times larger than the Sun, but it is very young, only 2 million years old. Resources.
