Noctilucent clouds are primarily composed of ice crystals at heights 50-70 miles above the earth's surface and form during the summer when temperatures in the mesosphere are coldest. Temperatures lower than about -120 degrees Celsius are required for its formation. This classic example was spotted during a flight between JFK airport in New York, US, and Heathrow airport in London, England.
