I would push open the sliding glass door and immediately look up, searching for stars sprinkled beyond the silhouetted trees. At the time, I couldn’t even begin to comprehend what I was seeing. Instead, each beacon of light represented a […] -
Watch Water Levitate, Flow Up, & Swirl the Wrong Way in the Other Hemisphere
The conventional wisdom is all wrong. Countless parents and teachers have gotten it twisted. The BBC and PBS aired bogus explanations. Even textbooks have botched the story.The Earth’s rotation, and the Coriolis effect that results, do not cause water to circle the drain in opposite directions in the Northern and Southern Hemispheres. Nautilus Members enjoy […] -
Forget “Earth-Like” Worlds

Why Spaceflight Will Never Be as Safe as Modern Aviation
Charles Lindbergh in 1923, four years before his trans-Atlantic flight. A light drizzle greeted Charles Lindbergh as he arrived at Roosevelt Field on May 20, 1927, at a little before three in the morning. Weeks of rain had ensured that the runway at the Long Island airport was in poor condition, soft and strewn with […]

The Few Tough Species That Survive the Rigors of Nothingness
The Expose-R module attaches to the ISS and holds samples in the harsh conditions of space.NASA In the 1800s, scientists imagined that life was brought to Earth by a rock that had been knocked off of a distant, life-filled planet. Now, over 100 years later, we are able to test this idea of “panspermia”—by sending […]

99 Problems, and a Wild Gecko Space Orgy Is Just One
By the time of this launch of the space shuttle Discovery in 2009, NASA knew well the dangers of lightning to spacecraft. At the launch of Apollo 12, in 1969, they were in the dark.NASA On July 19, Russia launched a satellite designed to study the effects of microgravity on, among other living beings, geckos. […]

The Most Symmetrical Objects in the World
If you’ve ever tried to give yourself a haircut, you know just how hard it is to make something precisely symmetrical. We value symmetry so highly in part because it’s really hard to achieve. Here are five of the most symmetrical objects humans have ever crafted, and why they were so hard to make.1. Gravity […]

Can You Identify These Cities From Their Light Signatures?
The light that a city emits is like its glowing fingerprint. From the orderly grid of Manhattan, to the sprawling, snaking streets of Milan, to the bright contrast of Kuwait’s ring-roads, each city leaves its own pattern of tiny glowing dots. See if you can ID these cities based on the way they shine. […]

Some Dead Satellites Refuse to Go Quietly to Their Graves
A map of large debris orbiting Earth, as seen from the North Pole.European Space Operation Centre (ESOC) High above us, tens of thousands of kilometers above our heads, there are orbiting graveyards. They are filled with satellites that have burned through their functional lives, now “buried” in space. The graveyards are filled for a reason: […]

19th-Century Code Helps 21st-Century Mars Rover Find Its Way
Back in the 1840s, Morse code was a ground-breaking approach for sending messages over a hot, new communications medium called the electrical telegraph. Earlier this year, the last telegram ever was sent, yet Morse code is not entirely out of a job. NASA’s cutting-edge Curiosity Mars rover, built by JPL (Jet Propulsion Laboratory), uses this […]

The Unlikely Rocks Found in Mosques, Siberia & Outer Space
A Penrose tiling, a 2D pattern that shows a similar lack of repetition as a 3D quasicrystal.Wikipedia Back in June, researchers at Ames laboratory in Iowa announced the discovery a new group of rare-earth quasicrystals—an unusual class of crystalline materials where the atomic structure boasts regular patterns that never repeat themselves. They resemble the intricate […] -
Two Good Ways to Really *Get* the Solar System
The Sun is one busy celestial body. In addition to giving us light, holding the solar system together, and providing the energy for almost every living thing on Earth, it’s also a grapefruit in a grass field in Austin, Texas, and a 50-foot yellow archway in northern Maine.Now, obviously this huge mass of incandescent gas is […]
