Learning to press words.

Just a note. I am a complete newbie to this whole wordpress malarkey so please bare with me if this page changes several time. As an example, “My past images” page, I am trying to create a gallery of past images, Whilst I have managed to create the gallery, I have no idea how to add more images. I will also appologise in advance for my poor grammar, spelling mistakes and general waffle. However, if you have any suggestions, or would like for me to add something or to link something here please let me know and I will try to accomodate appropriate requests. Thank you.

Dumbbell Nebula M27

Image

The Image was taken 26/10/2012. It consists of 15 sub frames of 2minutes exposure at ISO800.

The Dumbbell nebula (M27) is a planetary nebula located in the constellation of Vulpecula and lies somewhere near to 1300 light years away. The central star is a star that has died and now exists as a white dwarf. A white dwarf is one of the final states a star can achieve after it has exhausted  its hydrogen fusing power, essentially it is a dead star. Around 95% of all stars are thought to one day evolve into  white dwarfs after leaving the main sequence of star evolution. The white dwarf is created after the star expands into a red giant, shedding its outer layers to form the nebula that surrounds the star, eventually the star collapses under its own gravity to form a small and incredibly dense white dwarf.
