Did you just uncover an interesting tidbit of knowledge related to current science? Tell us.
Courtesy NASA?JPL-CaltechRemember last month when we posted a photo of the Earth and Moon taken by the Cassini spacecraft as it looked back from its location near the planet Saturn? Well, at the time, NASA made a request of all Earthlings to send in photos of themselves waving back at Saturn, and here are the results made into a collage of our Big Blue Oasis in space:

A dogfish shark and a sand tiger shark in Delaware Bay present a pretty good example of the old saying.

But they can't beat Minnesota-native astronaut Karen Nyberg. From her perch aboard the International Space Station, she's created an extensive gallery of images from space including this image of Minnesota that includes her hometown of Battle Lake. There are come very artistic displays of global weather activities in these photos.

But compared to more massive stars that explode into novae or supernovae, our medium-sized yellow star (or G-type main-sequence star) won't go out with much of a bang but more of a poof. During its death throes, as the Sun runs out of hydrogen and begins burning helium, its size will fluctuate until it swells up into a red giant big enough to engulf the inner planets, perhaps even Earth. This means it's going to get a lot hotter around here. If you want to get a better idea of what's in store for us, check out these dramatic and somewhat disturbing illustrations of the Sun's end times.
I really like the cool image showing one of the surviving Maya stone idols being scorched by the bloated Sun. It's Stela A from Copan, Honduras, and if you want to see a really impressive full-sized replica of that monolith, you can see it in the Science Museum of Minnesota's terrific new exhibit, Maya: Hidden Worlds Revealed.
...frogs use leaves as umbrellas! Very cool photo. The little critter is about 2 inches tall.
Bill Nye gives us a quick, and fun, lesson on how we can avoid problem asteroids of the future.

On this anniversary of his first steps on the lunar surface, I wonder what Neil Armstrong would have thought of this remarkable photograph taken yesterday by the Cassini spacecraft? In the center of a field of stars sits planet Earth and the Moon taken from more than 898,000,000 miles away!

I especially like the one for Einstein. National Science Day is celebrated in the India each year on February 28. Go here to check out some of his very cool artwork on Tumblr.
