This might indicate a "glaciological tipping point" on the Antarctic Peninsula, an important consideration as global warming continues to affect ocean temperatures.
The spacecraft recently burned 10 percent of its total fuel in a single 43-minute maneuver as preparation for the double gravity assist.
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.
Thanks to century-old photos taken by Danish pilots, we can study long-term changes in Greenland's glaciers.
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.
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.
Scientists used the new Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) in California to capture radio images of October's annular eclipse.
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.
New research indicates that the number of migrating birds decreases during severe space weather events. They are also more prone to becoming lost.
New research indicates that Mercury's thermal contraction was still occurring as recently as 300 million years ago.
Observations from ESA's Copernicus Sentinel-5P satellite indicate the ozone hole above Antarctica is one of the largest seasonal holes ever observed.
A NASA mission called APEP will launch three sounding rockets into the annular solar eclipse to measure changes in electric and magnetic fields, density, and temperature of the ionosphere.
NASA and the National Snow and Ice Data Center have released some troubling data about our planet's polar regions.
The Surface Water and Ocean Topography (SWOT) satellite recorded higher sea levels off California, indicating a marine heat wave.
A reanalysis of Apollo 17 seismic data has revealed that the Apollo 17 lunar lander base is creating its own moonquakes.
