Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Antares is the brightest star in the constellation of Scorpius and one of the brighter stars in all the night sky. Antares is surrounded by a nebula of gas which it has itself expelled. Radiation from Antares ' blue stellar companion helps cause the nebular gas to glow, as photographed above. Antares is located about 500 light years away.
