Upwards Lightning Travels to Edge of Space

from Cosmos Online

U.S. scientists have photographed what may be the biggest and brightest
gigantic lightning jet ever recorded, as it travelled some 65 km from the
top of thunderclouds to the edge of space.

As detailed in the journal Nature Geoscience, the images of this rare and
highly charged meteorological event were captured during Tropical Storm
Cristobel as it passed nearby Duke University in Durham, North Carolina,
in July 2008.

"[Gigantic jets] are essentially upward lightning from thunderclouds that
deliver charge just like conventional cloud-to-ground lightning. What
struck us was the size of this event," said study co-author Steven Cummer,
an electrical engineer at the university.
