Green laser beams were detected over Hawaii last month, and according to Japanese astronomers, a Chinese weather satellite is to blame.
On January 28, the National Astronomical Observatory of Japan published a video of a series of lights in the sky that had been captured by a camera mounted atop Mauna Kea, Hawaii's tallest peak. The topographic laser on NASA's ICESAT-2 satellite, which is used to track sea ice and forests, is what caused the light display, according to the organization's researchers.
As Vice pointed out this week, NOAJ later updated its YouTube post to clarify that their satellite wasn't the source of the lasers over Hawaii. The new video instead identified a Chinese Daqi-1/AEMS satellite that was launched last year as "the most likely possibility." The China Aerospace Science and Technology Corporation stated in a news release from 2021 that it is used to track carbon dioxide as well as nitrogen dioxide, sulphur dioxide, and ozone.
