Earth:Space jellyfish

From HandWiki
Jump to: navigation, search

A space jellyfish (or jellyfish UFO; also rocket jellyfish) is a rocket launch-related phenomenon caused by sunlight reflecting off the high altitude rocket plume gases emitted by a launching rocket during morning or evening twilight. The observer is in darkness, while the exhaust plumes at high altitudes are still in direct sunlight. This luminous apparition is reminiscent of a jellyfish.[1][2][3] Sightings of the phenomenon have led to panic, fear of nuclear missile strike, and reports of unidentified flying objects.[4][5][6][7][8][9]
