Atomic clocks, based on the minute oscillations of atoms, are the most precise timekeeping devices humans have created. Every year, scientists make adjustments that improve the precision of these devices. Now, they’ve achieved new performance records, making two atomic clocks so precise they could detect gravitational waves, those faint ripples in the fabric of space-time.

A six-month-long journey that could shape the future of humanity reached its nail-biting conclusion today. On May 5th, NASA launched its InSight Mars lander from California’s Vanderberg Air Force Base. On Monday afternoon, following “seven minutes of terror,” the craft reached its final destination – Elysium Planitia, a flat plain near the Red Planet’s equator

It’s the mother of all conspiracy theories: the unflinching belief that the 1969 Moon landing never actually happened. Proponents of this seemingly unshakeable conviction argue that what the masses perceived as a groundbreaking scientific achievement was in fact an elaborate fake: a hoax perpetrated by NASA and the US government on the American (and international)

An uninvited guest has been caught hitching a ride on the International Space Station, and it’s a worrying one. JPL-NASA Scientists have identified strains of Enterobacter collected from the space station’s toilet and exercise area. If you’ve heard of the genus before, it’s probably in relation to hospitals. Some Enterobacter strains can infect immunocompromised patients

The federal government on Friday released a long-awaited report with an unmistakable message: The effects of climate change, including deadly wildfires, increasingly debilitating hurricanes and heat waves, are already battering the United States, and the danger of more such catastrophes is worsening. The report’s authors, who represent numerous federal agencies, say they are more certain

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously believed, according to a seismic study that spans the Mariana Trench. The observations from the deepest ocean trench in the world have important implications for the global water cycle, researchers say. “People knew that

Researchers have developed catalysts that can convert carbon dioxide—the main cause of global warming—into plastics, fabrics, resins, and other products. The electrocatalysts are the first materials, aside from enzymes, that can turn carbon dioxide and water into carbon building blocks containing one, two, three, or four carbon atoms with more than 99 percent efficiency. Two
