Eye-popping. I love this kind of stuff. No, seriously. I love it!
If you haven’t made browsing the NASA Astronomy Picture of the Day website part of your morning routine, I strongly urge you to do so. If nothing else, you’ll see some great photos and maybe gain a little perspective on your life.
There are many places that I truly enjoy only in daydreams.
Ideal places. Idyllic places.
Every once in awhile, I stumble across a photograph that captures what I feel is a perfect spot at a perfect moment.
What would it have been like 15,000 – 20,000 years ago to be the first human to walk through a mossy woodland like this?
Not that I’d want to be walking around in what is now North Carolina or Kentucky or Georgia 15,000 years ago. I can barely stand the thought of camping in modern times. But still… the idea intrigues me.
Add to it the fact that these woods have a dark, damp misty quality… and you got me right where I live!
Why does a volcanic eruption sometimes create lightning?
Pictured above, the Sakurajima volcano in southern Japan was caught erupting in early January. Magma bubbles so hot they glow shoot away as liquid rock bursts through the Earth’s surface from below. The above image is particularly notable, however, for the lightning bolts caught near the volcano’s summit. Why lightning occurs even in common thunderstorms remains a topic of research, and the cause of volcanic lightning is even less clear. Surely, lightning bolts help quench areas of opposite but separated electric charges. One hypothesis holds that catapulting magma bubbles or volcanic ash are themselves electrically charged, and by their motion create these separated areas. Other volcanic lightning episodes may be facilitated by charge-inducing collisions in volcanic dust. Lightning is usually occurring somewhere on Earth, typically over 40 times each second.
