This Antarctic glacier dramatically retreated. Then, its ice shelf totally collapsed (satellite image)
This might indicate a "glaciological tipping point" on the Antarctic Peninsula, an important consideration as global warming continues to affect ocean temperatures.
Europe's JUICE probe will be 1st to use gravity of Earth and moon to slingshot to Jupiter
The spacecraft recently burned 10 percent of its total fuel in a single 43-minute maneuver as preparation for the double gravity assist.
Mars probe sees Red Planet atmosphere glowing green at night
Using ESA's ExoMars Trace Gas Orbiter, scientists have observed nightglow in Mars' atmosphere, a phenomenon where the night sky glows green, almost like an aurora.
Satellite data and 100-year-old images reveal quickening retreat of Greenland's glaciers
Thanks to century-old photos taken by Danish pilots, we can study long-term changes in Greenland's glaciers.
What is STEVE, and how is it different from the aurora?
Reference STEVE is an atmospheric phenomenon that is similar to yet separate from the aurora. It looks like a mauve streak across the night sky.
The West Antarctic Ice Sheet is melting, and it's too late to stop it
A best-case projection that meets ambitious Paris Accord targets suggests the West Antarctic Ice Sheet will melt three times faster in the 21st century than it did in the 20th.
1st-ever radio images of an annular solar eclipse showcase the sun's extended corona
Scientists used the new Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) in California to capture radio images of October's annular eclipse.
What are different types of clouds and how do they form?
There are 10 primary types of clouds on Earth. Here you can learn about what they're made of, how they form and how they are classified.
Severe space weather is messing up bird migrations, new study suggests
New research indicates that the number of migrating birds decreases during severe space weather events. They are also more prone to becoming lost.
Mercury was shrinking for at least 3 billion years — and it still might be today

The Surface Water and Ocean Topography (SWOT) satellite recorded higher sea levels off California, indicating a marine heat wave.
Mysterious moonquake traced to Apollo 17 lunar lander base
A reanalysis of Apollo 17 seismic data has revealed that the Apollo 17 lunar lander base is creating its own moonquakes.
Contrails: What are they and how do they form?
Reference Condensation trails, or contrails, are long, thin clouds that can form behind airplanes at cruising altitude. They are created by jet engines.
