Explanation: What are those red filaments in the sky? They are a rarely seen form of lightning confirmed only about 30 years ago: red sprites. Recent research has shown that following a powerful positive cloud-to-ground lightning strike, red sprites may start as 100-meter balls of ionized air that shoot down from about 80-km high at 10 percent the speed of light. They are quickly followed by a group of upward streaking ionized balls. The featured image was taken earlier this year from Las Campanas observatory in Chile over the Andes Mountains in Argentina. Red sprites take only a fraction of a second to occur and are best seen when powerful thunderstorms are visible from the side.

With the upheaval going on in Chile I feel that this will be regarded as a sign in the heavens.

As Jerry Lee Lewis would say, “Goodness, gracious, great balls of fire”.
Fantastic photo.

The world is not just stranger than I have imagined, it is stranger than I could imagine.
10% of C. That’s 18,600 miles per SECOND. That’s fast.
And don’t these things emit energy in the X-ray spectrum as well? Think I read that somewhere.
