The Earth, and its wealth, at night

If it were night everywhere at the same time, this is what the Earth would look like (click to enlarge). But that strange statement doesn’t explain the importance of this view. What this image shows us is a representation of global wealth. As Vox puts it:

What you see is that in rich countries, light is largely a proxy for population density. Observe the thick cluster of the US Northeastern Megalopolis and the even bigger cluster in northwestern Europe. In poorer regions, however, the map represents not just population density but also the actual availability of electrical lighting. Huge swathes of Africa are barely illuminated at night, and densely populated India looks rather dim.

But of course, if it were night everywhere, that would mean the sun would be gone and we’d all be dead. Money can’t fix that.

It isn’t a UFO … it’s a flying saucer

Flying saucers are real. According to Sploid, we invented them:

The NASA’s Low-Density Supersonic Decelerator (LDSD) project successfully flew a rocket-powered, saucer-shaped test vehicle into near-space in late June from the U.S. Navy’s Pacific Missile Range Facility on Kauai, Hawaii. The goal of this experimental flight test, the first of three planned for the project, was to determine if the balloon-launched, rocket-powered, saucer-shaped, design could reach the altitudes and airspeeds needed to test two new breakthrough technologies destined for future Mars missions.

And the video from NASA shows how the machine worked … or didn’t:

Translation: The thing crashed and burned big time, because the parachute turned into confetti.
