A Shocking Shot

Defence Research and Development Canada caught a photo of a bomb’s shockwave as it exploded. This explosion took place at the agency’s Experimental Proving Ground, a roughly 180-square-mile facility in Alberta.

Life On An Extinct Volcano

Inhabitants of the Azores island of São Miguel (in the Atlantic Ocean) live on an extinct volcano. This image, captured by satellite, shows the lakes that formed in the volcano’s valleys and the seven cities that sprung up around them.

Total Eclipse

This year’s only total solar eclipse happened Friday, March 20. The full eclipse was only visible from the Faroe Islands and the Svalbard archipelago, where this photo was taken.

Om Nom Nom

Bonus total solar eclipse image: This morning’s solar eclipse, as seen from Germany, wasn’t quite as total as it was in the Faroe Islands or Svalbard archipelago. Thomas Robitaille, who posted this on Twitter, had some fun by creating this Pac-Man-inspired shot.

Craters On Mercury

NASA obtained a better view of the ice deposits in the craters of Mercury’s northern pole. This image, taken by the Mercury Messenger spacecraft, will give scientists a way to better explore the area, which never sees the sun.

Message To Mars

Buzz Aldrin displayed his “Get your ass to Mars” shirt at Stonehenge earlier this week. The 85-year-old Apollo 11 pilot has recently pushed for colonization on Mars, even coming up with his own plan for how to get there.

Understanding A Bleeding Glacier

The mystery of why a glacier looks like it’s been bleeding for years may soon be cracked. Scientists took a sample from below the inaccessible ice of Blood Falls in Antarctica using a new device called the IceMole. It works by melting its way through ice like a electro-thermal drill, but it can change directions instead of just going straight down. They’re examining the samples, which may hold some answers about the chemical makeup and microbial existence deep within the falls.

Throwback Map

There are 299 submarine cables, either active or in development, that transport information around the world. This vintage-looking map shows how the cables connect continents, with a sea monster or two added in.

Outside Looking In

Scientists are turning to earthquakes to get a better picture of the inside of Earth. This visualization of the planet’s seismic tremors, with different colors representing different speeds, shows how the inside of the planet is structured.

Eye Art

Artist Graham Fink uses eye-tracking software to draw images like this one. By shining infrared light in his eyes, the software picks up the movements of his peepers and translates them into lines. Here’s a video of Fink at work.
