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.

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.

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.

In some places, it's actually rising.

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.

The Copernicus Sentinel-2 satellites are monitoring changes in the fire to aid civil protection and humanitarian response.

This summer, the German Aerospace Center is testing instruments for NASA's VERITAS Venus mission on Iceland's lava flows, a stand-in for the hellishly hot planet.

Astronomers using the James Webb Space Telescope have determined that stars in early galaxies transformed the gas throughout the universe from opaque to transparent.

Using data from NASA's Juno spacecraft, an international team has correlated the variations in Jupiter's bands to changes in the planet's magnetic field.

The moon and Mars will dance together in the night sky both tonight (May 23) and Wednesday night (May 24).

Tonight (May 19) is the new moon, and it's a rare "black moon," which occurs approximately once every 33 months.

A new study has determined the most likely origin of one repeating fast radio burst to be a dense object — potentially a neutron star — with a binary companion.

The sun fired a huge cloud of plasma directly at Earth on Sunday evening (May 7), an outburst that could boost auroras in the next day or so.
