Antares Region: Around the red supergiant star Antares (in the lower left part of the image) a lot is going on.The intensive radiation of the huge star (several hundred times bigger than our sun) excites emission and reflection nebulae. IC 4606 is the one around Antares and IC 4605 the blue one in the upper left of the image. Close to Antares to the right are the globular clusters M4 (big one) and the smaller NGC 6144. On the upper right there is a beautiful emission nebula around the star Alniyat or Sigma Scorpii.
