Blue Supergiant
Blue supergiants (BSGs) are hot luminous stars, referred to scientifically as OB supergiants. They have luminosity class I and spectral class B9 or earlier.
They are found towards the top left of the Hertzsprung-Russell diagram to the right of the main sequence. They are larger than the sun but smaller than a red supergiant, with surface temperatures of 10,000–50,000 K and luminosities from about 10,000 to a million times the sun.

Famous quotes containing the word blue:
“Rather than have it the principal thing in my son’s mind, I would gladly have him think that the sun went round the earth, and that the stars were so many spangles set in the bright blue firmament.”
—Thomas Arnold (1795–1842)
