And it’s no exaggeration to say that they have become an essential part of our infrastructure. Sixty-five years after the launch of Sputnik in 1957, there are thousands of satellites orbiting Earth. However, there is one thing you can be guaranteed to see moving in the sky every night, no matter where you live on the planet: satellites. You can’t be guaranteed to see each of them every night. Sometimes, a display of the fabled aurora paints the northern sky with searchlight beams of scarlet and swaying curtains of highlighter-pen green.īut all these things only happen occasionally. Stars rise and set during the night constellations come and go as the seasons pass planets waltz along the ecliptic, visiting the zodiacal constellations on their nonstop sightseeing tour of the heavens and shooting stars zip across the sky.
