International Space Station transiting the Sun

International Space Station transiting the Sun

by Eliza Teodorescu

The International Space Station, a man-made life supporting habitat and a most complex and unique laboratory of science orbits the Earth in only 90 minutes, that is 16 times a day! Even so, only occasionally, we earthlings have the privilege of seeing it's dark outline against the much brighter surfaces of the Sun or Moon.
The timing is of crucial importance as such an event lasts for the briefest of moments, more or less than one second. Blink and it's gone. In this frame, the ISS transits the Sun. The spectacle is enhanced by the large group of sunspots and some active regions which appear as bright veins on the surface of the Sun. What I find endearing is that the two objects, one so close and one so far, are both equally unreachable.
