These supernova remnants are moving at extraordinary speeds only visible to us in long-term timelapses.

A new theory suggests that NASA's Curiosity rover could be "burping" the surface of the Red Planet, releasing methane trapped beneath a salty crust.

The next total solar eclipse to hit the United States will be in 2033, but it will only be visible in Alaska. The Lower 48 won't get one until 2044.

NASA's Chandra X-ray Observatory images the firework-like remnants of the great supernova of 1181.

It's round two for the Atmospheric Perturbations around Eclipse Path (APEP) sounding rockets.

No, the date and path of the total solar eclipse have not been miscalculated.

Varda Space has written up the results of its groundbreaking W-1 mission, which successfully crystalized the metastable Form III of the antiviral drug ritonavir in space and returned it to Earth.

Launched in September 2023, the X-ray Imaging and Spectroscopy Mission (XRISM) — led by JAXA, in collaboration with NASA with additional contributions from ESA — has produced its first test images.

Supernova remnant 30 Doradus B, or 30 Dor B, is the (former) star of this new image.

Get a detailed look at Perseverance's current location on Mars — the ancient Jezero Crater.

Scientists have no idea what the spokes are.

The snow globe–esque image was created with Hubble data from 2006 to 2021.

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.
