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.


What if Apollo 11 had been a failure?

President Richard Nixon had a speech prepared in case things went wrong for the first men on the moon, Neil Armstrong and Buzz Aldrin, according to Gizmodo. It went:

“Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace. These brave men, Neil Armstrong and Edwin Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice.”

It wasn’t needed.

They were the first to walk on the moon. Fortunately, they weren’t the last.

Man on the moon: July 20, 1969

And here’s a Nova episode on the lunar mission:

I’ve probably said this before, but this was the greatest human achievement in history. So it’s frustrating to think that what I consider the most outstanding event of my lifetime happened 45 years ago.

C’mon, people. We’re now in the 21st century. We can do better. We already did.
