Swirling 250 miles (400 kilometers) above Earth, the International Space Station (ISS) completes a full orbit of our planet every 90 minutes or so. You can see it with your naked eyes at night (at least, you can see a white dot of steady-cruising light), but spotting the station during the daytime — as photographer Rainee Colacurcio did in the fiery photo above — requires a bit of technological assistance.

"My go-to setup is a dedicated hydrogen-alpha solar scope," which is a special telescope for observing the sun, Colacurcio told Live Science in an email.

The above photo, featured recently on NASA's Astronomy Picture of the Day blog, is a composite of several exposures of the sun stitched together with Photoshop and various other editing programs. Using a website called transit-finder.com, Colacurcio calculates exactly where and when the ISS will appear to pass in front of the sun near her location, then spends about an hour before the event focusing her solar scope on our local star. With a camera attached to the scope, she films for about 10 minutes as the satellite crosses the sun's gleaming face.

While the ISS sits like a bow on the top left corner of the sun's head in the new picture, no visible sunspots (dark splotches of intense magnetic activity) appear. According to NASA, that's because the sun is in the midst of a solar minimum, which is a period of low solar activity that occurs every 11 years or so.

While lower-than-normal activity is expected, both the current solar minimum and the previous one produced hardly any sunspots, NASA wrote, which is a bit unusual. Nobody really knows why — but at least it makes for some great photos.
