Red sprites and blue jets are both atmospheric and electrical phenomena that take place in the upper atmosphere. They take place above normal lightning; Blue jets happen in cone shapes above thunderstorm clouds, and are not related to lightning. They’re blue due to ionised emissions from nitrogen. Red sprites can appear as different shapes and have hanging tendrils. They occur when positive lightning goes from the cloud to the ground.
This bizarre electrical phenomenon usually occurs during thunderstorms and lasts for up to thirty seconds. Balls of lightening are said to behave in strange ways, hovering, rolling, hissing and sometimes passing through walls, in a way that seems completely unnatural. As a result, ball lightening has long been associated with aliens and ghosts.
WHAT WE STILL DON'T KNOW ABOUT LIGHTNING #2: • Most lightning strikes involve negative charge in the clouds and positive charge on the ground beneath. Occasionally the opposite occurs, also unexplained • We also don't know why gamma rays should be formed by lightning
Catatumbo Lightning - At the point where the Catatumbo River meets Lake Maracaibo in Venezuela, a constant lightning storm illuminates the sky for around 10 hours a night, for almost half the nights out of the year.
