Antares Rival of Ares - a photo on Flickriver

Target:
Antares, Greek for "rival of Ares", accompanied by NGC 6144 (upper left).
This rivalry stems from the colour and brightness of the planet Mars and the supergiant star Antares. Both are red in colour and for a few months every couple of years Mars is much brighter than Antares. Most of the time, though, Mars is near the same brightness or much fainter than Antares. Every couple of years Mars passes near Antares, which was perhaps seen as taunting the star, as Mars moves rapidly through the heavens while Antares, like all stars, seems fixed.
