the Moon and the Scorpion

   Tuesday evening August 25th watch for the 7-day old first quarter Moon to be about 5o from the reddish star Antares. This star, sometimes known as ‘the rival of Mars’ because the color of the planet and Antares are strikingly similar. This is most notable during the years when Mars passes by Antares and the two are together in the sky.
    From mythology Antares is the ‘heart’ of Scorpius the Scorpion. In reality Antares is a red supergiant star that is the 15th brightest night time star. As the brightest star in the constellation of Scorpius Antares is the alpha star or α Scorpii (alpha scorpii).
   Antares is so big in size that it dwarfs many other stars, yet there stars bigger than Antares!
