Tyndall’s Trail of Bergs

May 10, 2026

The Southern Patagonian Icefield is the largest expanse of ice in the Southern Hemisphere outside of Antarctica. The mass of glacial ice extends hundreds of kilometers along the spine of the Andes, feeding dozens of dynamic outlet glaciers that grind their way down from higher elevations. Many of these rivers of ice terminate in the sea or in proglacial lakes.

An astronaut aboard the International Space Station photographed one of these glaciers—Tyndall Glacier in southern Chile—through a layer of ethereal clouds on May 10, 2026. Fragments of ice that had calved off its terminus were visible floating on Lago Geikie.

Like most Patagonian glaciers, Tyndall has been shrinking since the end of the Little Ice Age about 150 years ago. Lago Geikie formed at Tyndall’s terminus around 1940, according to glaciologist Mauri Pelto of Nichols College, and gradually expanded as the ice retreated. Part of the glacier previously terminated in Lago Tyndall to the east, but thinning ice cut off that outlet by 2010, Pelto said. (The ice’s retreat also exposed bedrock along its eastern edge that contains scores of ichthyosaur fossils.)

Along with thinning, ice calving off the glacier’s front has reduced its volume. Tyndall has lost 2.2 kilometers (1.4 miles) in length since November 2022, Pelto said, following about a decade of limited retreat with considerable thinning. A significant calving event in March and April 2023 contributed to the recent uptick in ice retreat. During that time, satellites observed several large icebergs breaking away from Tyndall’s terminus.

Austral autumn in 2026 was a time of active calving retreat at Tyndall (and some neighboring glaciers), Pelto said, albeit more incremental than three years prior. “The substantial crevasses crisscrossing the glacier near the calving front lead to many smaller icebergs,” he said. On the other hand, larger tabular icebergs tend to form when there are fewer deep crevasses near the terminus and the glacier’s ice is thinner.

The ice cliff at the terminus casts a substantial shadow, which can help scientists estimate the height of the glacier’s front. Pelto’s calculations, using information about the Sun’s position provided with the image, indicate that Tyndall’s front loomed 30–40 meters (100–130 feet) above the lake surface in May 2026. Observations from orbit, including astronaut photographs, can help scientists monitor and understand glaciers in remote regions where ground-based observations are scarce.

As for what comes next for Tyndall, Pelto expects many more small icebergs to continue breaking off, given the heavily crevassed appearance of the calving front. “Look for a burst of iceberg production next fall.”

Astronaut photograph ISS074-E-582898 was acquired on May 10, 2026, with a Nikon Z9 digital camera using a focal length of 560 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 74 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Story by Lindsey Doermann.

San Francisco’s Metropolitan Mosaic

9 June 2026 at 05:00
A top-down photo of San Francisco shows dense gray urban infrastructure interspersed with green parks. Waves and ships are visible in the surrounding blue-green water.
May 27, 2026

A period of unsettled weather brought scattered showers and thunderstorms to California’s Bay Area on May 27, 2026. That afternoon, a break in the clouds left downtown San Francisco and nearby communities beneath mostly cloud-free skies, allowing an astronaut aboard the International Space Station to take this photograph.

The image captures two of the region’s iconic bridges. The Golden Gate Bridge connects the northern San Francisco Peninsula with Marin County to the north, while the San Francisco-Oakland Bay Bridge spans the bay toward Oakland to the east.  

Near the center of the image, Golden Gate Park stands out as a long, rectangular strip of green amid the dense urban landscape. Spanning more than 1,000 acres (400 hectares), the park encompasses meadows, gardens, wooded areas, and lakes. Additional green space toward the north around the Golden Gate Bridge is part of a national recreation area. 

The nadir (downward-looking) perspective also provides a clear view of the patchwork of street grids, which were laid out over San Francisco’s hilly terrain as the city grew in successive stages. In the heart of the downtown area, Market Street runs southwest to northeast and serves as a prominent divider between two distinct grid orientations: one aligned with the bay and the other aligned with the street.  

Along the northeastern and eastern waterfront, various structures extend into the bay. Toward the north, these include a historic wharf, seawalls, and piers—most built in the early 1900s, though some date back into the 1800s. The adjacent waters support heavy maritime traffic, including cargo and container ships, cruise vessels, and regional ferries.

Breaking waves are visible along the western coast, including at Ocean Beach, the 3.5-mile stretch of sandy shore adjacent to Golden Gate Park. On May 27, the National Weather Service warned of hazardous conditions at the region’s beaches due to strong northerly winds. Long-period swells from the northwest contributed to the increased risk of rip currents as well as sneaker waves in the days after this image was acquired.

Astronaut photograph ISS074-E-619284 was acquired on May 27, 2026, with a Nikon Z9 digital camera using a focal length of 800 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at NASA Johnson Space Center. The image was taken by a member of the Expedition 74 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet.

Digging Back in Time in the UAE

8 June 2026 at 05:01
Limestone ridges appear as linear features running north–south with orange-toned desert to the west and a darker-toned mountain range to the east.

About an hour’s drive east of Dubai’s gleaming towers and artificial islands, a quieter, more natural landscape takes shape. At the far northern edge of the Rub’ al Khali, a saffron-colored sand sea laps against the Al-Hajar Mountains. A series of pale ridges rises finlike from the desert plain, with the largest—Jabal al Fāyah—standing 412 meters (1,352 feet) above sea level.  

The Landsat 8 satellite captured this image of the ridges cutting across the Emirate of Sharjah in the northern part of the United Arab Emirates on October 23, 2025. To geologists, the limestone ridges are a reminder of the region’s watery past, signs that this land lay underwater tens of millions of years ago when the sedimentary rock layers were deposited.

Jabal al Fāyah functions as a barrier, trapping windblown sand in dune fields to its west. The weathering of iron-bearing minerals in the sand grains gives the dune fields their orange hue. To the east, the branching channels of overlapping alluvial fans extending from the Al-Hajar Mountains carry gravels and eroded sediments from basalts and other dark mafic rocks. 

The dark rocks to the east—part of the Samail Ophiolite—are known to geologists for being among the world’s largest, best-preserved, and most accessible exposures of ancient oceanic lithosphere, the rigid outer layer of Earth that includes both the crust and upper mantle. Oceanic lithosphere like this is normally subducted and recycled back into the mantle when tectonic plates collide. But in this area, a large section from beneath the Tethys Sea was scraped off and thrust onto the Arabian plate in a process called obduction.  

Development associated with Dubai appears as a light gray zone along the coast of the Persian Gulf with the dark gray Al-Hajar Mountains on the far right side of the image. A ridge lies in the middle of the image in a sandy area.

The Jabal al Fāyah ridges themselves are made up of marine limestone that was deposited on top of the ophiolite over tens of millions of years spanning the late Cretaceous through the early to mid-Paleocene. Limestone typically forms along continental margins in warm, shallow oceans, often in lagoons and coral reefs, out of the calcium carbonate found in the shells and skeletons of marine life. In many parts of the ridges, coral fragments and marine invertebrate fossils are visible embedded in the rock. A feature called Fossil Rock sits a few kilometers north of Jabal al Fāyah and adjacent to the limestone ridge Jabal Mulayḩah. It contains an abundance of snail, clam, and sea urchin remains. 

For archaeologists, the ridges are at the center of a much more recent tale of human adaptation and survival that has played out in just the past few hundred thousand years. The ridges and parts of the surrounding landscape—inscribed as a UNESCO World Heritage site in 2025—are dotted with dozens of archaeological sites that trace human occupation on the Arabian Peninsula back to between 210,000 and 120,000 years ago, to the Middle Paleolithic. That was a period when waves of anatomically modern humans (Homo sapiens) migrated out of Africa and shared the planet with other groups such as Neanderthals.   

Many of the sites contain stone flakes, blades, scrapers, hand axes, and other stone tools. The archaeological treasure trove offers early evidence of modern humans surviving in a harsh desert environment and raises questions about the routes modern Homo sapiens may have taken on their journey out of Africa.  

Geological evidence indicates that lakes periodically formed on the east side of the ridge, providing critical food and water resources that would have supported early inhabitants in this unforgiving climate. Rocky overhangs along the ridge would have provided shelter from the heat and wind. Some of the sites show evidence of intermittent occupation beginning as early as 210,000 years ago, making this one of the earliest signs of human habitation on the Arabian Peninsula.

Fighting Fire With Fire

5 June 2026 at 05:01
Several gray smoke plumes are visible drifting over a green landscape.
Smoke streams from fires in Australia’s Northern Territory in an image captured by the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA’s Aqua satellite on May 28, 2026.
NASA Earth Observatory/Michala Garrison

In May and June of most years, NASA satellites typically begin to detect large numbers of wildland fires throughout the Top End and Arnhem Land regions of Australia’s Northern Territory. On some days, especially in the afternoon, the blazes can resemble sizable wildfires in satellite imagery, spreading widely and producing expansive smoke plumes.

That was the case when NASA’s Aqua satellite acquired this image of smoke and fires on the afternoon of May 28, 2026. Often, however, fires burning in this area look smaller and less imposing. In the mornings just a few days earlier and later, for instance, NASA satellites detected little smoke despite observing many thermal anomalies, or hotspots, that indicated fire activity.

The pattern of burning, location, and timing are consistent with prescribed fires lit intentionally to manage the landscape. Land managers tend to light fires in the morning, and smoke builds over the course of the day. The process sometimes creates sizable plumes when there are updrafts and winds of moderate strength that carry smoke away from the fires, as happened on May 28 and again on June 2. The fires typically burn through the fire-adapted grasses, underbrush, and scattered trees in the region’s tropical savanna ecosystems.

Over the past few decades, the region’s land managers have combined deep-rooted Indigenous land management practices and modern technologies to establish large-scale landscape management programs such as the West Arnhem Land Fire Abatement project and Arnhem Land Fire Abatement. The goal of such efforts is to intentionally burn some of the savanna underbrush to create firebreaks and reduce fuel loads early in the dry season, reducing more destructive and emissions-intensive fires later in the season. The dry season generally begins in May and extends through September, according to Australia’s Bureau of Meteorology.

While research is ongoing, there are signs that the prescribed burning efforts are having the intended effect. Analysis of satellite observations of the fires suggests that prescribed burning efforts have shifted fire activity from late to early in the dry season, leading to a reduction in high-intensity fires and emissions.

A Moonlit Earth as Seen From Artemis II

4 June 2026 at 05:01
Earth’s full disk is seen through the window of a spacecraft. The glow of aurora, a sliver of the Sun, and fuzzy zodiacal light surround the planet, and city lights are visible on the continents.
April 2, 2026

One of the first images transmitted back to Earth from the Artemis II mission was a stunner. In a single image, Earth’s full disk appears amid celestial phenomena that illustrate its place in the solar system. And although the visible hemisphere appears to be awash in sunlight, it is actually lit by moonlight. The astronauts’ vantage point provided a rare opportunity to capture nighttime features—most notably lights from human habitation—from a new perspective.

An Artemis crew member captured the photo from the Orion spacecraft after it completed the translunar injection burn, which sent the spacecraft out of Earth orbit and on a trajectory toward the Moon. In the photo, Earth eclipses the Sun from Orion’s perspective, leaving only a small sliver of its bright light visible around the bottom right edge. Green auroras, caused by charged particles from the Sun interacting with Earth’s upper atmosphere, glow around the north and south poles (lower left and upper right, respectively).

The Sun’s light also produces the fuzzy glow, known as zodiacal light, that appears to the lower right of Earth. This phenomenon comes from sunlight reflecting off interplanetary dust. Skywatchers on Earth may see it at certain times of year around dawn or dusk as a faint column of light extending up from the horizon. Data collected by NASA’s Juno spacecraft on its journey to Jupiter suggest that Mars may be a significant source of the dust particles that produce zodiacal light. Earth’s other planetary neighbor, Venus, appears as the bright object in the bottom right of the image.

Earth’s full disk is seen through the window of a spacecraft. Various features are labeled. The glow of aurora, a sliver of the Sun, and fuzzy zodiacal light surround the planet, and city lights are visible on the continents.
April 2, 2026

On Earth itself, city lights are evidence of human activity. Bright areas appear in Spain, Portugal, and northern Africa (lower left), sub-Saharan Africa (center left), and Brazil (center right). Digital camera technology—with help from the illumination of a full Moon—made it possible to see these and other details of Earth’s surface and atmosphere in low light. The crew set the camera’s ISO to 51,200 to make it highly sensitive to light. For comparison, an ISO setting of 100 or 200 is common for daytime photography.

Previous nighttime views of Earth taken from spacecraft may look very different from this photo but have also inspired and enlightened. For instance, the Apollo 12 crew photographed Earth eclipsing the Sun in 1969; astronaut Alan Bean would go on to depict his impressions of the event in paintings.

More recently, astronauts aboard the International Space Station have photographed the planet at night from low Earth orbit, while NASA’s Black Marble nighttime lights product suite uses satellite observations to produce science-quality records of nighttime lights at daily, monthly, and yearly time scales. Those programs provide sustained data records, while the Artemis II photo is distinctive as a single human-captured full-disk view showing many low-light features at once.

Cindy Evans, senior exploration scientist in the Astromaterials Research and Exploration Science Division at NASA’s Johnson Space Center, was working in the Science Evaluation Room during the Artemis II mission and was one of the first people on Earth to see the image. Evans was struck both by its beauty and the perspective revealed by all the visible solar system features. “I love the image so much because it was taken with Earth in moonshine, and shows Earth as a solar system body, a dynamic planet interacting with the solar wind, and a place harboring life,” she said.

The image is scientifically valuable, as well, said Miguel Román, Deputy Director for Atmospheres and Data Systems at NASA’s Goddard Space Flight Center. “It speaks powerfully to the breadth of what NASA does across science and human exploration,” he said. Román studies artificial light at night, as viewed from space, as a measurable signal of human activity.

“[This photo] reminds us that Earth at night is visually compelling, physically complex, and scientifically underexplored,” Román said. “I see this image as a glimpse of what Earth science can become in the future.”
