Heavy metal may rain from the skies of planet WASP 76b | Science News

On one distant world, “heavy metal” could be a weather forecast. Telescope observations indicate that an exoplanet nearly 400 light-years away has iron rain. The planet, dubbed WASP 76b, is an extreme kind of exoplanet known as an ultrahot gas giant (SN: 7/30/19). These worlds “are complete oddballs,” says astronomer David Ehrenreich of the University [...]

Neil Armstrong’s Spacesuit Was Made by a Bra Manufacturer | History | Smithsonian Magazine

For the suit’s creator, the International Latex Corporation in Dover, Delaware, the toughest challenge was to contain the pressure necessary to support life (about 3.75 pounds per square inch of pure oxygen), while maintaining enough flexibility to afford freedom of motion. A division of the company that manufactured Playtex bras and girdles, ILC had engineers [...]

We’re Better Equipped to Find Extraterrestrial Life Now Than Ever Before | Science | Smithsonian Magazine

... however small the probability of seeing a signal from E.T. is, those chances are soon going to be a lot better than they have been in the past. Sure, after decades of listening, there is still no message. But with more data to sift through, and new technologies with superior search capabilities, odds of [...]

How an Interstellar Starship Could Actually Explore Alpha Centauri

Last year, Stephen Hawking and Russian billionaire Yuri Milner hatched an ambitious plan to send a tiny probe to the Alpha Centauri star system. Travelling at 20 percent the speed of light, the researchers weren’t entirely sure how the probe was supposed to stop once it arrived at its destination, or whether it would even [...]

Consciousness Isn’t Self-Centered – Issue 82: Panpsychism – Nautilus

... how does felt experience arise out of non-sentient matter? The Australian philosopher David Chalmers famously termed this the “hard problem” of consciousness.1 Unlike the “easy problems” of explaining behavior or understanding which processes in the brain give rise to various functions, the hard problem lies in understanding why some of these physical processes have [...]

Physicists link quantum memories across the longest distance ever | Live Science

A team of scientists in China has linked quantum memories over more than 30 miles (50 kilometers) of fiber optic cable, beating the previous record by more than 40 times over. This feat is an important step toward a hack-proof internet, scientists said. — Read on http://www.livescience.com/quantum-memory-entangled-far.html

String Theory | Number Theory | What Is String Theory

Scientists have found what they say is a link between complex number theory and string theory: a specific kind of elliptic curve from a torus. ... specifically defined elliptic curves embody the overlapping space between number theory and superstring theory in particular, other geometric shapes with specific qualities could fit the same logic gateway shared [...]

Earth’s Got a New, Tiny Moon | RealClearScience

The Minor Planet Centre has just announced that the Earth has been orbited by a second moon for the past three years or so. But while excitement about the discovery is growing, it is important to keep in mind that this moon isn’t as impressive as our main satellite. It is extremely faint – it [...]
