Reflecting on the ISS

By Phil Plait | October 17, 2011 10:12 am

Randy Halverson is an astrophotographer who takes gorgeous pictures of the sky and puts them together into amazing time lapse videos (see Related Posts below for links to his work). On Google+ this morning he posted a picture he took last night, and it’s simply stunning: the International Space Station rising into the Milky Way, with both reflected on a lake’s still waters:

What a fantastic shot! I’ve tried getting similar pictures, but never managed to get one as nice as this. It takes dark skies; Randy was about 300 km west of Sioux Falls, South Dakota when he took it, where there’s almost no light pollution. The Milky Way is obvious; you can see the bulge of the central region of the galaxy, and the disk tapering off to the top of the frame. Pictures like this are always a good reminder that we live in the mid-plane of a big spiral galaxy.

When Randy got this shot the ISS was rising over the southwestern horizon. 100 meters across, 380 km up, and moving at 8 km/sec, the station reflects a lot of sunlight and moves rapidly enough to create a bright streak in short time exposures… and bright enough to create a strong reflection in the water.

A funny thing: as I looked over the picture, I saw a faint streak not too far from the ISS. Read More
