International Space Station Captured Crossing the Sun During Spacewalk in Stunning Footage.

French astrophotographer Thierry Legault captured stunning footage of the International Space Station (ISS) crossing the sun during a spacewalk by NASA astronauts Stephen Bowen and Warren "Woody" Hoburg. The entire solar transit lasted just 0.75 seconds, and Legault imaged the ISS whizzing past three sunspot groups. The ISS orbits Earth every 90 minutes, traveling about the distance from Earth to the moon and back again in just one day. The secret to capturing such an iconic moment? Precision planning and clear skies!
