Is there a blue star in the universe?
An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky. Astronomers calculate that Rigel is approximately 700 and 900 light-years away, and yet it appears almost as bright as a star like Sirius which is only 8.3 light-years away.
Is a blue Sun Real?
Though the sun may appear yellow or reddish to the naked eye, it’s actually an ordinary white star. And the blue version released by NASA was made using a specific wavelength of ultraviolet light known as CaK, which is emitted by ionized calcium in the sun’s atmosphere.
Is the blue giant bigger than the Sun?
The true monsters of the Universe are blue supergiant stars, like Rigel. These can be a blue star with surface temperatures of 20,000 – 50,000 Kelvin and can be 25 times larger than the Sun. Because they’re so large, and burn so hot, they use up their fuel very quickly.
