Lightning strikes can be an exhilarating and terrifying sight to behold from the ground, but what’s wilder is that these intense bolts of plasma sometimes powerfully erupt in the opposite direction, zigzagging up into space in dazzling displays known as gigantic jets. 

Now, scientists led by Levi Boggs, a research scientist at the Georgia Tech Research Institute, have described the strongest gigantic jet ever seen, which sprang up from cloudtop in Oklahoma and darted 50 miles above Earth’s surface, where it delivered the largest charge transfer to space on record.
