join the exploration of cosmos: possible worlds

Television’s most watched science show returns March 9. Cosmos: Possible Worlds, created and executive produced by Ann Druyan and hosted by astrophysicist Neil deGrasse Tyson, continues the legacy that Carl Sagan began more than 40 years ago. Episodes transport viewers across space and time with one-of-a-kind animations (above), holograms, and reenactments of world-altering discoveries. NAT GEO WILD Enjoy the Critter Fixers TV debut Veterinarians Vernard Hodges and Terrence Ferguson have been classmates, partners in an animal hospital—and now they’re co-stars of a show about their work. Critter Fixers: Country Vets premieres February 23 at 10/9c on Nat Geo WILD. NAT GEO LIVE Experience an era When Women Ruled the World A Nat Geo Live event may be coming to a venue near you. This month, learn about ancient queens with Egyptologist Kara Cooney, author of When…

the promise of a circular economy

WE FEEL BAD when we throw out things that shouldn’t have become trash (like uneaten, past-its-prime produce) or expend resources needlessly (like leaving lights on when we’re away). This guilty feeling is deeply ingrained; the origins of the expression “waste not, want not” can be traced to the 1500s. But we do waste, in ways big and small. The result is this shocking fact: Of the minerals, fossil fuels, foodstuffs, and other raw materials that we take from the Earth and turn into products, about two-thirds ends up as waste. And, more likely than not, that waste is part of a larger environmental problem. “Plastic trash drifted into rivers and oceans; so did nitrates and phosphates leaching from fertilized fields. A third of all food rotted, even as the Amazon was deforested…

the backstory

YEAR AFTER YEAR, as autumn in Alaska is ending, Ryota Kajita goes looking for winter’s first ice. A Japanese-born photographer living in Fairbanks, Kajita believes that “everything—even if it appears to be insignificant—connects to larger aspects of our Earth.” An example, he says, is the ice, after it has frozen over ponds and lakes but before it’s been obscured by snow. Kajita has been shooting photos through the ice since 2010 for his project, Ice Formations. He’s captivated by the geometric patterns he sees: fizzy fields of bubbles under the frozen surface, and snow and ice crystals dusted across it. Many photos are compositions of trapped, frozen bubbles of methane and carbon dioxide. Though Kajita loves to photograph the formations, their existence worries him. As Earth’s northern regions warm, the melting of…

finding our way to the future

IN THIS SECTION A Giant Geode Microbial Art Mudskipper Parenting Arctic Racing IT WAS A RAINY NIGHT when the future became a place, one you could visit. A downpour at sunset couldn’t discourage the 200,000 people who had gathered for the opening ceremony of the 1939 New York World’s Fair. “World of Tomorrow” was the theme of this art deco land of promise. There were television sets, calculating machines, and a robot. For the first time, people saw these things that would change their lives. But on that night they had come to hear the greatest scientific genius since Isaac Newton. Albert Einstein was to give brief remarks and flip the switch that would illuminate the fair. The spectacle promised to be the largest flash of artificial light in technical history, visible…

geology a giant among geodes

ANY GEODE MIGHT MAKE US WONDER: What geologic forces form these hollows lined with crystals? But the Pulpí Geode, discovered in an abandoned Spanish mine, takes wonder to a different scale. One of the world’s largest geodes, it’s an approximately 390-cubic-foot cavity whose walls bristle with imposing gypsum crystals, some nearly seven feet long. Now scientists are hoping to uncover how these colossal crystals developed. They seem to have been made by a very specific recipe: a 250-million-year-old supply of the mineral anhydrite, a climate hospitable to crystal formation, and lots of water and time. In the resulting chemical soup, larger crystals may have cannibalized smaller ones to boost their own size, while swings in the local temperature could have accelerated the crystal growth even further. Though key chapters remain incomplete, this…
