Lake Chad’s Water, Wetlands, and Dunes Astronauts have photographed the diminishing lake in Central Africa for decades, most recently in January 2025, as its area remained just a fraction of its past ...

Your challenge is to use the comments section to tell us where it is, what we are looking at, and why it is interesting.

Last blog post of for this field season, as Olivia mentioned in her science post, we were able to collect an important amount of high-quality data to further our knowledge of firn aquifers and try to ...

The warm, shallow ocean waters of the tropics have talkative “forests” of their own. Brightly colored mounds of coral grow in the warm ocean waters, quickly when nutrients are plentiful and more ...

Carbon is the backbone of life on Earth. We are made of carbon, we eat carbon, and our civilizations—our economies, our homes, our means of transport—are built on carbon. We need carbon, but that need ...

Since its launch in February 2013, Landsat 8 has collected about 400 scenes of the Earth’s surface per day. Each of these scenes covers an area of about 185 by 185 kilometers (115 by 115 miles)—34,200 ...

Throughout its long history, Earth has warmed and cooled time and again. Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or ...

For CSIRO scientist Catia Domingues and her colleagues, being able to show that climate simulations and observations were in better agreement than they previously seemed was only the first payoff of ...

The Sun provides the energy that drives Earth’s climate, but not all of the energy that reaches the top of the atmosphere finds its way to the surface. That’s because aerosols—and clouds seeded by ...

All matter in the universe that has a temperature above absolute zero (the temperature at which all atomic or molecular motion stops) radiates energy across a range of wavelengths in the ...

In the black dome of night, the stars seem fixed in their patterns. They rotate through the sky over the seasons so unchangingly that most cultures have used the presence of one or another ...

For a chemical compound that shows up nearly everywhere on the planet, methane still surprises us. It is one of the most potent greenhouse gases, and yet the reasons for why and where it shows up are ...
