Alan Friedman’s shot of the solar prominence was not the only amazing picture he took of the Sun last week. He also caught something pretty special: the Orbiter Discovery, docked with the International Space Station, as the pair crossed the face of our star:
Alan used a filter that lets through only a very narrow wavelength of light emitted by hydrogen (called Hα for those of you keeping track at home), so this tracks the activity of gas on the solar surface. He also inverts the image of the solar disk (makes it a negative) to increase contrast. Somehow this adds a three-dimensional quality to the picture, and reveals an amazing amount of texture. I swear I had a rug in my bedroom growing up that was this texture (though somewhat cooler and less burny).
Amazing. He had to rush from giving a talk, drive to the location, set up, and be ready to snap this event… which lasted only a fifth of a second! As it was he barely made it; had he missed his location by a few hundred meters the docked spacecraft would’ve been off to the side of the Sun.
