The New World Atlas of Artificial Sky Brightness

How far are you from a naturally dark night sky? In increasing steps, this world map (medium | large) shows the effect of artificial night sky brightness on the visual appearance of the night sky. The brightness was modeled using high resolution satellite data and fit to thousands of night sky brightness measurements in recent work. Color-coded levels are compared to the natural sky brightness level for your location. For example, artificial sky brightness levels in yellow alter the natural appearance of the night sky. In red they hide the Milky Way in an artificial luminous fog. The results indicate that the historically common appearance of our galaxy at night is now lost for more than one-third of humanity. That includes 60% of Europeans and almost 80% of North Americans, along with inhabitants of other densely populated, light-polluted regions of planet Earth. via NASA http://go.nasa.gov/297zoqx

Larger Than Life

A harvestman cuts an intimidating figure, here silhouetted against a sunlit leaf in the Hofma Preserve in Grand Haven, Michigan. Also known as daddy longlegs, these creatures are often mistakenly labeled as spiders. Though both spiders and harvestmen are arachnids, harvestmen are closely related to the scorpion.

Crazy Illusion Somehow Transforms Rectangles Into Circles in the Mirror

Crazy Illusion Somehow Transforms Rectangles Into Circles in the Mirror

What in the sorcerous hells is this? Kokichi Sugihara’s ‘Rectangles and Circles’ illusion is a mind-bending visual trip that turns squares into circles and circles into squares right in front of your face. Different shapes are placed at a mirror and what you see in front of you is totally different from what you see in the mirror. It’s like the mirror is actually a portal to another dimension where squares are circles and circles are squares. Seriously … what the hell?

Fatal Tesla Crash Proves Full Autonomy Is the Only Solution for Self-Driving Cars

The investigation
into a death that occurred while a Tesla Model S driver was using Autopilot has filled the internet with dystopian-sounding headlines. Self-driving car driver died for the first time after crash in Florida. Self-driving Tesla was involved in fatal crash. But this was not a “self-driving car” that killed its “driver.” This was a human driving a semi-autonomous car. And this points to why fully autonomous vehicles
are the only types of self-driving cars that make sense on our streets. Ever.
