Starry sky. The image is centred on the constellations of Gemini (right) and Cancer (left). The brightest object at upper centre is Mars which is almost aligned with Pollux and Castor, the two main stars in Gemini. They are found to the right of Mars and Pollux is the closest to the planet. The constellation of Cancer is not easily recognisable. The main feature in it is the presence of the open star cluster known as the Beehive or Praesepe (M44). The cluster is visible at centre left as a small fuzzy patch. It is formed by about 300 stars and lies at a distance of some 520 light years from the Earth. The image was taken from Vancouver, Canada.
