A camera attached to a telescope on Hawaii’s tallest peak recently captured footage of a series of eerie, bright green lines that shot across the night sky for just over a second. Experts say the unexpected light show resulted from a rapid burst of lasers fired toward Earth by a NASA spacecraft.
The laser lines appeared on Jan. 28, flashing across the sky one by one in just over one second. A video(opens in new tab) of the lasers was captured by the Subaru-Asahi Star Camera — co-owned by the National Astronomical Observatory of Japan (NAOJ) and Japanese news agency Asahi Shimbun — attached to the Subaru telescope on top of Mauna Kea, a dormant volcano on Hawaii’s Big Island.
