Beauty in the Eye of Hubble

Posted by michael on from the eye-candy dept.

An anonymous submitter cut-and-pasted yet another beautiful Hubble picture, of a planetary nebula around a dying star. Wow.

    Most of the released Hubble photographs have been given artificial colors. This one is no exception. It is still a beauty. http://www.geocities.com/lilmacumd/escape.html

      Black and white wouldn't be quite as stunning, IMO.

      Mmm.. Galactic donut..

    Nebula are black n white? I know they're duller than these pictures but are you sure about black/white?

      From what I understand they are as black and white as the stars we normally see. The Stellar Eggs, for example are awesome in appearance but if you took away the false coloring you end up looking at a fuzzy muddle of greys.

      Oh, no. They really have colors. You get the images from the CCDs in black and white because you have to take one expose through each filter (which is then just a map of intensity at that waveband). But you then add the images to get color.

      HST images (as well as other telescopes's outputs) tend to be false colored for two reasons:

      1. Because stretching the color tables often brings out subtle details. You can see this is a true and stretched image of Jupiter, for example.

      2. Many (most maybe even) HST images include wavelengths that we can't actually see, into the IR and UV. If you want to see those wavelengths, you'll have to false color.

      I do sort of wish that they'd always include a little note in the captions stating that the color tables have been stretched or otherwise manipulated. But they seldom do. It's just a dream I have.

      The Fast Facts page says what wavelengths are used in this image. H-alpha and N II are both red, so they probably mapped one of those to green.

      So is this photo have the true color configuration?

    Artificial colors or not - just being able to see such an image is an affirmation of life. Thank god for technology!

    Could we please refrain from plagiarizing titles? Admittedly this is not as bad as ripping article summaries, but still doesn't sit right. Very neat picture in any case.
