    I love space porn. But I have a question. In the last 5 years or so, I have read multiple times how earth-based telescopes have gotten sharper and more powerful than the Hubble. If that is the case, why aren't we inundated with Interstellar money shots? It seems like Hubble is the Official photographer of all things cool.

    @Jack of all Tirades R.O.A.C.H.: I've read similar things about the sharpness.

    I had a long reply, but it didn't come out right so I'll sum up as follows: other people are bitches... Also I think they are privately funded or held closer to the specific research institution.

    @Log1c: If that's what's holding images back, I suppose this is one argument for sometimes having large spendy government-funded programs. You know, so all the rest of us can get off on space porn too.

    Can someone explain to me: How are the colors in these photos achieved? Naturally? Or do they use some kind of element-based filter?

    @burlybax: its called the 'Hubble Spectrum'.
    Oxygen is mapped to Blue, Hydrogen to Green and Sulfur to Red. Its a bit shifted from what their normal emissions are.

    The imager takes one black and white picture with specific filters for each of the above wavelengths. The images are then given color and combined. Sometimes with pictures from other telescopes like CHANDRA for Xray emissions and other things.

    An excellent description of the complete process is here: [astroprofspage.com]

    @Dayburner: And that's what a gallery format should be for. But todays samples: "A Gallery of paragraphs of what I liked on last nights episode of Glee" (Gawker); "A Gallery of Intersting Examples of Joe Wilson being an Asshole" (Gawker); Fashin Week (Jezebel) - Okay, fashion week's legit.

    @nozer: I feel like we're doing the same number of galleries as ever. Only thing that's new is now if I have 20 videos to post, I can put them up as a gallery, and it doesn't crash your browser -- I hope. Posts with 20 videos sometimes mess up people's browsers otherwise.

    So every time I watch Rocky Horror Picture Show and the audience response line comes up "What the f***'s a Triffid?" I think about this and also about the picture of the Trifid Nebula that you can see in the queue for Space Mountain.

    I'm not sure that you got the explanation right here; these, for the most part, look like normal long-exposure shots - I bet we could even figure out how long the exposures are from the length of the star trail. The multiple short exposures thing lets us generate images like this: http://www.analemma.de/english/analem.html

    @capnrob: If you click the link and RTFA, it says some of them are long-exposure and some of them are combos of short ones.

    Absolutely fantastic. It looks like that church is getting sucked into space! I'd love to see more posts like this.
    Reminds me somewhat of Troy Paiva's long-exposure photos of junkyards and aircraft graveyards.
