Google briefly allowed anyone to create AI-modified versions of satellite imagery available in Google Earth—before quickly reversing its decision as people shared examples of AI-generated pictures that illustrated the potential for misinformation and disinformation.
There is no shortage of generative AI tools that already allow people to create AI-modified images of real buildings and cities based on user prompts. But Google’s aborted attempt to incorporate its Nano Banana 2 AI image generator as a Google Earth feature made it even easier for anyone to create modified versions of authentic imagery depicting real locations—something that Google boasted about when initially promoting the new feature.
“For the first time, you can generate custom images using Google Earth’s satellite, aerial, and 3D imagery alongside Nano Banana, which creates concepts grounded in the real world,” wrote Bryan Horowitz, product manager for Google Earth, in a company blog post on July 30.
Satellite images have revealed new damage to Amazon data centers in the Middle East along with at least one crucial Saudi oil facility, following missile and drone attacks by Iran and its Houthi allies.
The images from Europe’s Copernicus Sentinel-2 satellites provide evidence of a widening war as the United States and several Gulf states exchange military strikes with Iran, the Houthi faction in Yemen, and Iran-backed militias in Iraq. Such satellite images also offer independent verification of claimed war damage, despite the US government having pressured US commercial firms and even Europe to restrict satellite imagery of the region.
Three Amazon data centers in the United Arab Emirates and Bahrain were already previously damaged by Iranian drone strikes on March 1. Those earlier attacks stuck Amazon with months of expected repairs and forced Amazon Web Services customers in the Middle East to migrate workloads to other cloud regions.

Seen from space, the Danger Islands along Antarctica’s rocky coastline have a distinctive pink-orange coloration, with tiny trails of pink closer to its shorelines.
However, the unique colors of these islands aren’t attributable to minerals, colorful lichens, or other kinds of usual causes. According to NASA, the Danger Islands look the way they do because of their iconic residents.
Now, data about the influence these creatures have on their surrounding habitat his helping scientists monitor the health of an entire Antarctic ecosystem from space.
A Colorful Surprise Spotted from Space
According to a new study’s findings, the vast colonies of Adélie penguins on the Danger Islands are the culprit behind their coloration. More specifically, it is the guano these flightless birds produce that has permanently altered their coloration when seen from space, resulting in pink stains along the shoreline environments where these waddling creatures reside.
Surprisingly, the guano stains offer an effective means of tracking the diets of these birds, which can serve as a good proxy for the broader changes occurring in Antarctica’s marine environment.

Primarily, this is because these large penguin colonies can deposit enough guano that their presence is detectable in satellite imagery, as is revealed in Landsat satellite imagery collected since the mid 1980s. The distinctive pinkish hue observed on the Danger Islands today indicates a diet rich in krill, whereas eating more fish would produce very different color signatures—all of which can be detected through satellite observations.
Decades of Penguin Activity Revealed
For the new research, scientist Casey Youngflesh with the Department of Biological Sciences at Clemson University, along with her coauthors, analyzed more than three decades of Landsat satellite imagery collected from 1984 through 2013.
These observations, combined with samples collected from field studies involving penguin colonies, helped the researchers establish links between specific color patterns and the balance of krill and fish in the birds’ diets.
Among the team’s findings, the data revealed a very close relationship between penguin food sources and the extent of sea ice in the surrounding area, particularly during the breeding season of these shore-dwelling birds.

Colonies of penguins along the warmer Antarctic Peninsula and West Antarctica—locations where there is less sea ice—revealed a greater reliance on krill. By contrast, Eastern Antarctic penguins consumed more fish in areas where sea ice persisted for longer. This higher-quality food source is also linked to improved chick growth and a greater degree of overall population success in the long term.
“Sea ice is such a hugely important factor in the Antarctic marine environment,” said Youngflesh. “The structure of the region’s food web is changing in response.”
The Future of Antarctic Environments
Along with what the team’s findings reveal about the lives and sustenance patterns of penguins, they also bring to mind several questions about the future of their habitat.
Although sea ice in Antarctica was found to be primarily stable during the years Youngflesh and her team examined, since 2013 it has shrunken significantly, reaching record low levels. Further declines are expected in the decades ahead, signaling changes that could push Adélie penguins toward increasingly krill-dependent diets.
This could become complicated as commercial krill fishing has seen expansion in recent years, and recovering populations of whales and seals are also competing for the same food source.
Right now, researchers are working to produce new computer models based on data obtained from the Landsat 8 and Landsat 9 satellites, which will help them continue to observe penguin diets from orbit. This data provides an unusual—but also a remarkably effective—means of monitoring the changing health of Antarctica’s fragile ecosystem.
The findings were reported in a new study, “Space-based monitoring of penguin diet links sea ice, food webs, and population change,” which appeared in the journal Current Biology on July 20, 2026.
