To help cure the planet’s ailments, Zhen Dai suggests antacid. In powdered form, calcium carbonate—often used to relieve upset stomachs—can reflect light; by peppering the sky with the shiny white particles, the Harvard researcher thinks it might be possible to block just enough sunlight to achieve some temperature control here on Earth. Dai’s work calls […]
Between this past Christmas and New Year’s Day, Brian Metzger realized he had his home to himself—no emails coming in, no classes to teach—and maybe, just maybe, the glimmer of an answer to one of astronomy’s most stubborn mysteries. He chased hard after the lead, worried a little error could unravel everything or that someone […]
Click:hanfu dress male female On Thursday, Darpa gathered roboticists in the Louisville Mega Cavern, in Kentucky, and gave them a mission: Design robots to navigate a grueling subterranean course of tunnels and caves, some of the most unforgiving environments on Earth. They’re calling it the Subterranean Challenge, but you may as well call it the […]
I don't know much about making movies or the special effects involved, but I can imagine a scene from the 1970s during the creation of the first Star Wars movie. In one scene, they need to show an escape pod traveling away from a rebel blockade runner with the runaway droids R2-D2 and C-3PO. Things […]
Oh, you think you are pretty awesome with the basketball trick shots? Well, maybe you are—but can you score with a shot from an airplane as it flies by? That's what we have here with the Harlem Globetrotters (although it seems like Dude Perfect might have done this too). For me, this is a classic […]
Earlier this year, a three-year-old video of researchers extracting a long, twisted tube from a reptile’s bleeding nostril went viral. To date, it has accumulated more than 30 million views and set off a moral panic. The straw that broke the turtle’s beak also did a number on the camel’s back. Companies like Starbucks, Ikea, […]
This weekend, SpaceX began what is slated to be its busiest week ever by successfully launching its largest payload to date: a communications satellite dubbed TelStar 19V. Perched atop the company’s Cape Canaveral launch pad, a shiny new Falcon 9 rocket roared to life at 1:50 am Eastern on Sunday morning, lighting up the predawn […]
On Monday, November 26th, following a six-month journey across hundreds of millions of miles of deep space, NASA's InSight spacecraft will arrive at Mars in suitably dramatic fashion, hitting the top of the planet's atmosphere at 12,300 miles per hour—several times faster than a speeding bullet—shortly before 12:00 pm PST (3:00 pm EST). If all […]
WIRED ICON Jill Tarter, cofounder of the SETI Institute NOMINATES Margaret Turnbull, astronomer investigating alien biology When she met Jill Tarter more than two decades ago, one of Margaret Turnbull’s first questions was, “How can somebody work with you?” Tarter was leading the Center for SETI Research at the time; Turnbull was an astronomy student. […]
Half a century ago, astronauts aboard NASA's Apollo 8 mission become the first humans to leave low Earth orbit, traverse the 240,000 miles separating our planet from its moon, and loop around that natural satellite to look upon its forever-hidden far side (not dark side) with their own eyes. The first crewed voyage to orbit […]
