Compared to Jupiter’s moon Europa, our planet is practically a desert, as this NASA image shows.

(Details at APOD: 2012 May 24 - All the Water on Europa)

Wow. I’ve seen the Earth droplet many times, but never next to Europa. Perspective, you haz it.

All the Water on Planet Earth

Illustration Credit & Copyright: Jack Cook, Woods Hole Oceanographic Institution, Howard Perlman, USGS

Explanation: How much of planet Earth is made of water? Very little, actually. Although oceans of water cover about 70 percent of Earth’s surface, these oceans are shallow compared to the Earth’s radius. The above illustration shows what would happen is all of the water on or near the surface of the Earth were bunched up into a ball. The radius of this ball would be only about 700 kilometers, less than half the radius of the Earth’s Moon

Shadow Puppets!

Ok, one last eclipse photo before returning to our usual programming.

This was the view from the geostationary MTSAT satellite as yesterday’s annular eclipse moved across the Pacific. You can see the shadow of the Moon like a burn mark east of Japan as it moved toward North America!

And this time-lapse by Cory Poole using a filter to highlight the chromosphere … well, it’s simply brilliant:

Ray Troll stratigraphy/geologic time. I’m printing this out and hanging it above my desk. 

Know your geologic history.

And don’t put a nautilus in the back of your pickup truck. That is not how we treat nice fossils.
