Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Monitoring the cryosphere is crucial for assessing, predicting and adapting to climate change.

The Copernicus Polar Ice and Snow Topography Altimeter (CRISTAL) mission will provide a full picture of the changes taking place in some of the most inhospitable regions of the world. It will carry – for the first time – a dual-frequency radar altimeter, and microwave radiometer, that will measure and monitor sea-ice thickness, overlying snow depth and ice-sheet elevations.

These data will support maritime

The NASA/ESA/CSA James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, occurred 160 000 light-years from Earth in the Large Magellanic Cloud. SN 1987A was observed on Earth in 1987, the first supernova that was visible to the naked eye since 1604 — before the advent of telescopes.

The year 2024 promises to be a busy one for American Moon landings, all under a new partnership between NASA and the space industry. A first attempt under the Commercial Lunar Payload Services (CLPS) initiative ended in disappointing failure last month, but a second, led by Houston-based Intuitive Machines, will attempt on Thursday to return the United States to Moon for the first time in fi

A company from Texas is poised to attempt a feat that until now has only been accomplished by a handful of national space agencies, but could soon become commonplace for the private sector: landing on the Moon. If all goes to plan, Houston-based Intuitive Machines will guide its spaceship named Odysseus to a gentle touchdown near the lunar south pole on Thursday at 2249 GMT, then run experim

Further embracing the New Space era, ESA is to develop two new Scout satellites: NanoMagSat and Tango. NanoMagSat will measure Earth’s magnetic field to help assess space weather hazards and continue on from ESA’s current Swarm mission. Tango will measure greenhouse-gas emissions from human activity and complements the upcoming Copernicus Carbon Dioxide Monitoring mission and the Sentinel-5 mission, as well as the current Sentinel-5P mission.

In a significant move to bolster the United States' wildfire management efforts, NASA has officially become an associate member of the National Wildfire Coordinating Group (NWCG). This collaboration opens new avenues for the space agency to work alongside federal agencies and other partners, leveraging its vast technological and innovative resources to enhance understanding and management of wil

In a significant advancement for atmospheric science, researchers have introduced a novel algorithm designed to enhance the accuracy of aerosol monitoring using China's FY-4A satellite. This development, detailed in a recent publication in the journal Engineering, represents a collaborative effort among the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences, the National S

Our understanding of how galaxies form and the nature of dark matter could be completely upended, after new observations of a stellar population bigger than the Milky Way from more than 11 billion years ago that should not exist. A paper published today in Nature details findings using new data from the James Webb Space Telescope (JWST). The results finds that a massive galaxy in the early
