Cool photo

They did more than just toy with that photo. Anyone have any idea from which telescope that pic was taken? I don't see it mentioned. Anyway, there's no way you get that sort of detail of another star, from a telescope. I'm thinking it's just an artist's representation.
 
very cool. I set it as my desktop background

They've definitely toyed with the colours. No star would appear to be black in some parts on a natural photo.

While I also think they had to adjust the foto, I don't think the black is unreasonable.

Since the entire thing is obviously very bright in real-life, they had to turn down the brightness drastically...which might explain the black spots. Also, black spots do appear on the sun naturally.

If I remember correctly, these kind of shots are usually patched together from 2 fotos though. 1 for the eruptions around the star/sun itself and 1 foto for the actual star itself cause they need different light sensitivities for the two. In the first foto, a physical disk blocks out the main part of the sun to prevent the camera from being blinded @ the high sensitivity.
 
Definitely Photoshopped, but a lovely pic nontheless. They usually take the images from all 3 different telescopes(optical, x-ray & gamma ray, radio) and combine them for a complete image.

Yeah its an incredible pic and my desktop background now too. I hope it isnt photoshopped too much as its always nice to believe that this type of beaty exists out there. (Wow I am in a philosophical mood today)
 
If I hold my mouse over it, it says: "Artist rendering of the powerful flare that erupted from the red dwarf star EV Lacertae."

That sucks. Sorry people. I thought NASA only publishes real photos. For rendered stuff, one might as well go to digital blasphemy or some other site:(

Still looks good though.:cool:
 
Hehe knew it. Reason being, if the pic was taken from earth (Let's just assume we could come even CLOSE to that sort of magnification), it'd be distorted by the atmosphere to such a degree that nothing near that quality would be visible. If it was taken from space...well, we just don't have lenses big enough.
When looking at stars through even the most powerful of telescopes, they still appear as dots and things like red-shift and blue-shift and other parts of the colour combination of the light is used to decipher the velocity of the star, relative to us, it's composition, etc. It's actually quite interesting, but not as glamarous as people seem to think.

Damn, you just killed off my dreams and aspirations of becoming an astro-physicist! And all this time I thought it was the glamorous, hollywood life! Gonna have to take a long, hard look at my life now!
 
:p Don't worry, I know several astro physicists, and they're all horrible, sad people who are nasty to you in order to make themselves feel better ;) :p
