Blue stars are made of the same stuff as all the other stars in the Universe; they're about 75% hydrogen and 24% helium with trace amounts of other elements.The color of a star comes from its...
Blue stars are massive, luminous, spectral type O. O stars have a surface temperature of 30,000°-50,000°C and masses of 20-100 solar masses. Their spectra are dominated by emission lines of singly...
A blue star is a star on the main sequence and thus not dying. Actually, blue stars are fairly new, while red ones are generally older (not necessarily/ entirely true). This is the result of a...
