See SWOT mission's unprecedented view of global sea levels

The Surface Water and Ocean Topography (SWOT) satellite is sending down tantalizing views of Earth's water, including a global composite of sea surface heights. The satellite collected the data visualized above during SWOT's ...

JWST takes a detailed look at Jupiter's moon Ganymede

Nature doesn't conform to our ideas of neatly-contained categories. Many things in nature blur the lines we try to draw around them. That's true of Jupiter's moon Ganymede, the largest moon in the solar system

JWST looks at the debris disk around a white dwarf

Pluto with a super-cryovolcano? Why not! All the elements are there, just not in the way we normally think of volcanoes. And cryovolcanoes are the reason why Pluto's surface looks the way it does. A recent research paper ...

Machine learning provides a clearer window into ocean motion

Oceanographers use satellites to peer down at Earth and measure the elevation of the ocean's surface. This information can help them map the circulation of the ocean's currents and understand the role this movement plays ...
