Cosmic Dance Of Spiral Galaxies: Arp 238

Nu Scorpii

One of the most interesting areas of the night sky, Scorpius holds a myriad of nebula and beautifully contrasting coloured stars.

Moving towards the tail, you'll find Nu Scorpii a binary star system 7 stars.

If that alone isn't enough to get your mind wondering how all these stars are orbiting each other, the star system itself is the eye of a horses head ! Albeit a nebulous head.

IC 4592 is a reflective nebula, with the blue light reflected from fine dust, that blue light is coming from the Nu Scorpii system above.

Pull out and you'll see the whole region contains many star forming areas with reflective features.

Eruption of Tvashtar volcano on Jupiter's moon Io (March 1, 2007)

For ten years the stargazer dreamed of taking a picture like this. The dreamer knew that the White Desert National Park in Egypt's Western Desert is a picturesque place hosting numerous chalk formations sculpted into surreal structures by a sandy wind. The dreamer knew that the sky above could be impressively dark on a clear moonless night, showing highlights such as the central band of our Milky Way Galaxy in impressive color and detail. So the dreamer invited an even more experienced astrophotographer to spend three weeks together in the desert and plan the composite images that needed to be taken and processed to create the dream image. Over three days in mid-March, the base images were taken, all with the same camera and from the same location. The impressive result is featured here, with the dreamer -- proudly wearing a traditional Bedouin galabyia -- pictured in the foreground.
