A crowd beats the heat with spray from a fire hydrant in Seattle. A new method for measuring urban heat exposure shows that more densely populated neighborhoods may face higher heat and longer hot ...

A recent impact in the Moon’s enormous Keeler Crater is illustrated here using images from NASA’s Lunar Reconnaissance Orbiter. The impact hit the crater’s central peak, and debris formed enigmatic ...

Heat waves, such as the record-breaking Siberian heat wave in 2020, are having lingering impacts on Arctic ecosystems. Credit: Andrei Zverev/Flickr, CC BY-NC 2.0 Now Kwon et al. suggest that the ...

NASA’s Juno spacecraft snapped this image of Jupiter’s moon Ganymede in 2021. New experiments might help scientists identify exotic forms of ice present in Ganymede’s interior and brought to the ...

Around 1.1 billion years ago, the oldest and most tectonically stable part of North America—called Laurentia—was rapidly heading south toward the equator. Laurentia eventually slammed into Earth’s ...

Enterprise Rupes, a large fault that cuts across the Rembrandt Basin crater (the large crater on the right) on the surface of Mercury. This fault—and many others like it—may have resulted from the ...

High biomass levels make the Palmer Deep submarine canyon in Antarctica a preferred foraging site for penguins, such as these off Anvers Island. New research investigates the origins of this biomass.

Rocks are important in subsurface engineering, but they are mostly invisible, extremely heterogeneous, and difficult to access. Thus, data on rock properties is scarce and uncertainties are large. Liu ...

A satellite image of the Juruena River shows areas of deforestation in Mato Grosso, Brazil. Dark green areas are intact tropical forest, light green areas are cattle farms, and yellow or brown areas ...
