From rivers and oxbow lakes to crop-field patchworks and mineral sediments, Landsat has seen it all. A program of NASA and USGS, the satellite initiative has documented the Earth’s surface since 1972, making it the longest continuous record of our planet’s ever-evolving landscapes. And to mark Earth Day 2026, the organizations launched a playful way to interact with some of their findings collected over the past five-and-a-half decades—a name generator.

Using the tool is simple: type in your name, or any word, and Landsat returns it in the form of vertical snapshots of a wide range of terrain. Just like we see with composites of Mars, for instance, scientists have digitally enhanced some images to highlight specific features. Those used for “Your Name in Landsat” sport a wide array of hues, textures, and patterns that glimpse the diversity of our planet’s surface.

Landsat is an incredible resource that features time-lapses of changing land use over several decades. Even this playful name generator allows you to hover over individual images and learn the exact locations—down to the coordinates—and all of the program’s data is publicly accessible. For example, the “C” in “Colossal” above is a vertical view of a cloud-speckled Deception Island in Antarctica, and the “A” is the uniquely shaped Lake Mjøsa in Norway.

The evolution of rivers that split into multiple channels is a scientific challenge in terms of modeling and prediction. On the other hand, these rivers are widespread and play a key role for ecosystems’ life, groundwater recharge, and therefore, water security. They are also extremely sensitive to hydroclimatic changes, leading to shifts in precipitation, erosion and sediment transport.

Zhao et al. [2026] investigate the drivers of river evolution for 97 multithread river reaches worldwide, spanning diverse climates and morphologies. The study reveals the key role of intermittency for river evolution. In particular, higher flow intermittency could lead to more even flow partitioning among threads, therefore impacting hydrology and ecosystems. With flow variability increasing after climate change, rivers are likely to increase their thread count, thus impacting livelihoods and ecosystems.

Unwanted vessels left to decay release fibreglass shards into the water, harming marine life. Steve Green – with his trusty van Cecil – is determined to clean things up

Steve Green, a boat engineer from Cornwall, was pulled over by the police just before Christmas. He was driving a decrepit-looking VW campervan and towing an even more dilapidated yacht up to Truro. He hadn’t broken any laws, but he admits that Cecil the campervan, which runs on donated chip oil from local pubs and has a crane and a winch on the front, “wasn’t quite what VW intended”.

Green (and Cecil) are on a mission to rid the beautiful hidden creeks of Cornwall’s Helford and Fal rivers of 166 abandoned fibreglass yachts, which are leaking plastic and toxins into the predominantly marine waters. Marine biologists have likened the thousands of shards of fibreglass they have found embedded in the flesh of sea-creatures in areas with wrecks such as these to asbestos, a substance known to have a noxious effect on humans.

Green uses a detachable crane system at the front of his van to move around bags of plastic after they have been weighed. Cecil is upholstered in recycled denim
