  • Waiting for July 12 will be hard

    From Quadibloc@21:1/5 to All on Fri Jul 1 00:41:12 2022
    This recent news story https://arstechnica.com/science/2022/06/nasa-teases-extraordinary-images-captured-by-its-webb-telescope/
    notes that
    - the James Webb Space Telescope has captured its first science images;
    - these will not be released until July 12
    - astronomers who have seen them have been brought to tears by how much better they are compared to anything we have had before

    So some exciting news is coming up.

    Dr. Becky (Rebecca Smethurst) has some thoughts on it:

    I'm wondering what colour? The images are IR right?

    Presumably the false color palette they choose will depend on the
    number of channels they're presenting. Or in the case of a single
    channel, probably the "heat" pseudocolor palette they've used for all
    the test shots they released.

    Yes. But the images will be given false color, so we will be able to see
    them with our own eyes.

    Out of curiosity, given that Hubble images are usually shown, not in
    natural colors, but in the "Hubble palette", with R, G, and B each given
    to particular major spectral lines, I checked to see if the same ions responsible for those lines also had lines in the infrared, so that one
    could make Hubble palette-equivalent images with the Web.

    I think I found that there were infrared lines in two of the three cases,
    but I could have been mistaken, as my search had been cursory.

    I'm fine with black and white representations of the IR. I don't need a crayola sketch.

    The most important instruments will be collecting multiband data. That
    can't be reasonably displayed in black and white. So for this we'll
    see various false color palettes used. Most commonly, I imagine, ones
    where the wavelength of the mapped colors corresponds to those of the
    source data (that is, red for the longest wavelengths, blue for the
    shortest).

    Even the single band data is better displayed with a pseudocolor
    palette, because both in terms of our eyes and of our display devices
    they allow us to see a greater intensity range than we can manage with grayscale.
