This picture was supposed to feature a comet. Specifically, a series of images of the brightest comet of 2021 were being captured: Comet Leonard. But the universe had other plans. Within a fraction of a second, a meteor so bright it could be called a fireball streaked through just below the comet. And the meteors flash was even more green than the comets coma. The cause of the meteors green was likely magnesium evaporating from the meteors pebble-sized core, while the cause of the comets green was likely diatomic carbon recently ejected from the comets city-sized nucleus. The images were taken 10 days ago over the Sacramento River and Mt. Lassen in California, USA. The fireball was on the leading edge of this years Geminid Meteor Shower -- which peaked a few days later. Comet Leonard is now fading after reaching naked-eye visibility last week -- but now is moving into southern skies. Almost Hyperspace: Random APOD Generator
