Betelgeuse is a red supergiant star, 10 times more than the mass of our sun.
According to scientists, Betelgeuse star is ejecting a dense and hot cloud material into space, which cools down to form a dust cloud. These dust particles in the space are blocking the view from the earth by shielding the star’s light.
Scientists have determined the cause of dramatic dimming of massive star Betelgeuse which is 725 light-years away using the Hubble Space Telescope rotating in the earth’s low orbit.
