"Japanese Astronomer Captures NASA's Mysterious Green Lasers"
Japanese astronomer Daichi Fujii recorded green pulsing lines shooting across the cloudy night sky on September 16, 2022, which were later identified as NASA's Ice, Cloud and Land Elevation Satellite 2 (ICESat-2) using motion-detecting cameras. It's the first time the satellite's green laser pulses have been spotted from the Earth's surface. The satellite uses laser light to get an exact measurement of the height of the Earth's ice, water, and land surfaces. The laser fires 10,000 times a second, shooting six beams of light to Earth.
