    Todays pic is a great nebula piccy, originally covered by one of Event Horizon's posts when he did Pic Of The Day, this view is very different.


    The Crab Nebula from VLT

    The Crab Nebula, filled with mysterious filaments, is the result of a star that was seen to explode in 1054 AD. This spectacular supernova explosion was recorded by Chinese and (quite probably) Anasazi Indian astronomers. The filaments are mysterious because they appear to have less mass than expelled in the original supernova and higher speed than expected from a free explosion. In the above picture taken recently from a Very Large Telescope, the color indicates what is happening to the electrons in differentparts of the Crab Nebula. Red indicates the electrons are recombining with protons to form neutral hydrogen, while blue indicates the electrons are whirling around the magnetic field of the inner nebula. In the nebula's very center lies a pulsar: a neutron star rotating, in this case, 30 times a second.

    A larger version of this piccy can be found here, this is a 838K Jpeg image. Although not much larger in size as far as actual dimensions go, it is of a much larger file size and the quality of the picture is much higher due to this.

    You know, it was only last night that i was wondering where this very daily thread had gone.

    Good to see it back Mark, and even if you only do it every so often i think it's a great contribution to the forum :)

    I found that the pics were becoming harder to find with so much of the good stuff already being covered, so I decided to slow down the rate of posting, plus it seems to get a better response at this slower rate of posting, I think that they were becoming too commonplace.

    Stunning pic Mark, can't comprehend the sheer power behind an explosion like that, mind boggling.
