When Spanish conquistadors entered the Aztec capital of Tenochtitlan in 1519, they described a sight so horrifying that many later historians believed it had to be exaggerated. According to their accounts, a massive tower and racks built from thousands of human skulls stood near one of the city’s most important temples. For centuries, these descriptions…

A giant world orbiting a distant sun-like star has given astronomers an unexpected glimpse into the weather systems of some of the coldest known exoplanets. Using observations from the James Webb Space Telescope (JWST), researchers have identified evidence of salt-rich clouds in the atmosphere of GJ 504 b, a massive gas giant often referred to…

For most of scientific history, chemical elements were identified through materials that could be handled, heated, weighed or examined in a laboratory. Helium followed a very different path. It first emerged not from a rock, a gas sample or a chemical experiment, but from a thin yellow line hidden within sunlight.According to a Science Museum…

The Pantheon in Rome is one of the best-preserved examples of ancient Roman concrete, standing strong for nearly 2,000 years. For centuries, engineers and historians have puzzled over one of the greatest mysteries of the ancient world. Why have Roman buildings survived earthquakes, storms and nearly two millennia of wear while many modern concrete structures…

For decades, discussion about California’s next major earthquake has tended to revolve around a single fault. The southern stretch of the San Andreas has long been viewed as the state’s most closely watched geological boundary, largely because it has remained quiet since the mid-19th century despite continuing movement beneath the surface. That long silence has…

Far beyond the Milky Way, vast collections of galaxies continue to drift, gather and occasionally collide. One such region has drawn astronomers’ attention for decades. Known as CL0016+1609, this immense galaxy cluster contains hundreds of galaxies bound together by gravity and shines strongly in X-ray light. A newly highlighted image from NASA’s Hubble Space Telescope…

Mount Etna erupts with incandescent lava fountains and massive ash clouds, illuminating the Mediterranean night. Mount Etna in Italy is one of the most well-studied volcanoes in the world. It has been erupting for thousands of years, and scientists have been observing it closely for decades. But a new study from Cornell University has revealed…
