Tracy Arm’s Post-Tsunami Landscape

Elegant Figures | 7 May, 2026
Carved over millennia by the pressure and motion of glacial ice, the valley walls cradling the Tracy Arm fjord in southeast Alaska continue to be reshaped. In summer 2025, following the rapid retreat of South Sawyer Glacier, a large landslide sent rock careening into the fjord, altering the wider landscape in a matter of minutes.

A Light in the Dark

Elegant Figures | 7 May, 2026
A thin sliver of Earth's edge is brightly illuminated against the vast darkness of space in this April 3, 2026, image taken during the Artemis II mission. Artemis II was the first crewed flight in a series of missions to test NASA's human deep space capabilities, paving the way for future lunar surface missions.

A Sea of Spinning Clouds

Elegant Figures | 6 May, 2026
Over the Southern Ocean surrounding Antarctica, winds can whip around the globe relatively unimpeded by land. Intrepid sailors termed these southern latitudes the Roaring Forties, Furious Fifties, and Screaming Sixties on account of the strong prevailing winds.

“Near-miss” Tsunami in Alaskan Cruise Area Offers Lessons for Steep Landscapes Near Glaciers

State of the Planet | 6 May, 2026
The study also points to broader lessons: as glaciers retreat in warming regions, the risk of related hazards can increase, and improved monitoring may help reduce some of those dangers....

Unlocking the Mystery of X-ray Dots

Elegant Figures | 6 May, 2026
A new "X-ray dot" found by NASA's Chandra X-ray Observatory - which could look like this artist's illustration released on April 28, 2026 - could explain what the hundreds or potentially thousands of these objects are.

Melting Snow Off Shivelyuch

Elegant Figures | 5 May, 2026
Shivelyuch (also called Shiveluch), the most northerly active volcano on the Kamchatka Peninsula, is one of the most active volcanoes in the world. On a near-daily basis, satellites detect new signs of activity within its horseshoe-shaped caldera, including thermal anomalies, hot avalanches and debris flows, and ash deposits that darken the surrounding landscape.

The Lego Natural History Museum, and the question of scale

For my birthday this year, my wife bought me the newish Lego kit Natural History Museum 10326. (Well: actually she bought me a Chinese knock-off for 1/3 the price, but that's not the point.) It's a lovely kit and I had a great time building it.

NASA’s Curiosity Rover Frees Its Drill From a Rock

Elegant Figures | 5 May, 2026
This series of images shows NASA's Curiosity Mars rover as it got a rock stuck to the drill on the end of its robotic arm and, after waving the arm and running the drill a few times, finally detached the rock. The imagery showing the entire process was captured by the black-and-white hazard cameras on the front of Curiosity's chassis and by navigation cameras on its mast, or head.

Ahuachapán and Its Restive Neighbors

Elegant Figures | 4 May, 2026
Volcanic activity takes on many forms in western El Salvador. The land near the city of Ahuachapán is pockmarked with craters and covered with recent lava flows. Meanwhile, a geothermal field feeds geysers, heats mineral pools, and powers a long-operating energy plant. The area is part of a volcanic landscape that stretches more than 1,000 kilometers (600 miles) along the Pacific coast from Guatemala to Panama, composing the Central American Volcanic Arc.

Record-Setting Retreat of Hektoria Glacier

Elegant Figures | 3 May, 2026
To say something moves at a glacial pace is to imply sluggish, unhurried change. But what transpired over the course of 15 months at Antarctica's Hektoria Glacier was uncharacteristically quick. Between January 2022 and March 2023, the glacier lost about 25 kilometers (15 miles) in length. That included a two-month period in which the terminus retreated more than 8 kilometers (5 miles)--the highest rate of grounded glacial ice loss observed in modern history.
