“What happening above that volcano? Something very unusual -- a volcanic light pillar. More typically, light pillars are caused by sunlight and so appear as a bright column that extends upward above a rising or setting Sun. Alternatively, other light pillars -- some quite colorful -- have been recorded above street and house lights. This light pillar, though, was illuminated by the red light emitted by the glowing magma of an erupting volcano. The volcano is Italy's Mount Etna, and the featured image was captured with a single shot a few hours after sunset in mid-June. Freezing temperatures above the volcano's ash cloud created ice-crystals either in cirrus clouds high above the volcano -- or in condensed water vapor expelled by Mount Etna. These ice crystals -- mostly flat toward the ground but fluttering -- then reflected away light from the volcano's caldera.”

I think that may be light reflected off the clouds. You're welcome!

Even the land surrounding the volcano is glowing red, great pic. Thanks.

Bill - I don't care what your scientifical gobbledigook says, that's a lightsaber!

Just like those folks who stormed Washington D.C. last January, I know I'm right, regardless of what your "facts" say!

Awesome!!!

I am a sympathetic Star Wars fan, Elivs, but light pillars are a thing in atmospheric optics that preceded the lightsaber by, well, a long time!

My sentiments exactly, Pat!

It really is, Donna. You're welcome!

My pleasure, Patti. Isn't it a fabulous shot!?

It sure is, Cyndi!

That looks so cool! But shouldn't it be properly titled, "Lightsaber over Mount Etna"? (asked the Star Wars nerd)
