Tycho's Supernova Remnant [edit]

This cellular-looking object is Tycho's Supernova Remnant. As a huge ball of exploding plasma, it was Irving Langmuir who coined the name plasma because of its similarity to blood plasma, and Hannes Alfvén who noted its cellular nature. The filamentary blue outer shell of X-ray emitting high-speed electrons is also a characteristic of plasmas. This is a false-colour image since x-rays are invisible to the human eye.

What looks like a microscopic biological cell, is in fact a huge Supernova Remnant. But it's no coincidence; as a huge ball of exploding plasma, it was Irving Langmuir who coined the name plasma because of its similarity to blood plasma, and Hannes Alfvén who noted its cellular nature.

The image can be found on the page about plasma, was sourced from Nasa, and is credited to Credit: NASA/CXC/Rutgers/J.Warren & J.Hughes et al.

  • Nominate and support. - Iantresman 12:43, 24 September 2005 (UTC)[reply]
  • Support. Particularly informative. Shows something most people don't get to see. - Mgm|(talk) 21:06, 24 September 2005 (UTC)[reply]
  • Fake colors picture or real colors ? Ericd 18:09, 25 September 2005 (UTC)[reply]
    • all pictures of this type use "fake" colors --jacobolus (t) 20:53, 25 September 2005 (UTC)[reply]
    • This is a false-colour x-ray image in which the energy levels (in keV) of the x-rays have been assigned a colours as follows: Red 0.95-1.26 keV, Green 1.63-2.26 keV, Blue 4.1-6.1 keV. All x-rays images must use processed colours since x-rays (as are radio waves, infra-red) are invisible to the human eye. But they are not invisible to suitable equipment, such as x-ray telescopes. --Iantresman 21:23, 25 September 2005 (UTC)[reply]

Support - I will marginally support with the caveat that the KeV-color correlation data is added to the image description page.--Deglr6328 18:23, 26 September 2005 (UTC)[reply]

  • Comment - Love the picture, but need to add something about the "false colors" to the caption, in addition to the full information given on the image page. CapeCodEph 21:49, 26 September 2005 (UTC)[reply]
    • Added comment to caption and more detailed information to the image's description page. --Iantresman 08:42, 27 September 2005 (UTC)[reply]

Oppose. I usually love space pictures, but this one doesn't do it for me somehow. Raven4x4x 07:14, 29 September 2005 (UTC)[reply]

  • Oppose. The same, I've seen better space pictures. Enochlau 23:31, 29 September 2005 (UTC)[reply]
  • Oppose. I have to agree, there's many more striking space images. This doesn't do it for me at all. --ScottyBoy900Q∞ 03:50, 30 September 2005 (UTC)[reply]
  • Support - This is a spectacular view of unleashed forces in the universe. Let's not get smug by saying 'I've seen better'. JoJan 19:40, 30 September 2005 (UTC)[reply]
    • I'm not being smug. I'm just saying I don't particularly like the picture. Raven4x4x 02:18, 1 October 2005 (UTC)[reply]
