AS MANY OF YOU KNOW, IM AN AMATEUR ASTRONOMER... And I love observing Doubles. The Red Supergiant, Antares, is the brightest star in Scorpius, thus its called alpha Scorpii. It is also (like most stars) a double, though its companion is very elusive in amateur telescopes. But on very clear nights, I do see it now and then. Its worthy to note, that it usually appears green next to the bright orange-yellow of Antares. The color green is not known to exist in stars, but there it is... an olive spark against the blackness of space, in belligerent defiance of the temperature spectrum.
