Image: As this Copernicus Sentinel-3 image captured today shows, the Netherlands remains pretty much snow-covered thanks to days of sub-zero temperatures following the country’s first major snowstorm in a decade.

Galileo has started testing Open Service Navigation Message Authentication (OSNMA) in its signal-in-space, allowing the first-ever OSNMA-protected position fix to be successfully computed. Testing will continue over the next months, ahead of a so-called ‘public observation’ phase. This is the first-ever transmission of authentication features in open GNSS signals of a global navigation system.

For the first time in over a decade, the European Space Agency (ESA) is seeking new astronauts. Tune in to ESA Web TV on Tuesday 16 February from 13:00 CET (12:00 GMT) for briefings in six languages and all you need to know.

Within the constellation Cygnus, an elderly star and its massive companion are having one last hurrah, flinging off mass at an incredible rate before they explode as supernovae and collapse into a black hole. Now, researchers including recent Embry-Riddle Aeronautical University graduate Laura M. Lee have mapped the elderly star's orbit around its oversized and equally ancient partner. In

A team led by astronomers at the University of California, Riverside, has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the past. Galaxies that appear to have little to no dark matter - nonluminous material thought to constitute 85% of matter in the universe - complicate astronomers' understanding of t

Ball Aerospace was selected to build the spacecraft for NASA's Global Lyman-alpha Imager of the Dynamic Exosphere (GLIDE) heliophysics science Mission of Opportunity. GLIDE will study variability in Earth's exosphere, the upper reaches of Earth's atmosphere where it touches space, by tracking far ultraviolet light emitted from hydrogen. Dr. Lara Waldrop of the University of Illinois Urbana

Sierra Nevada Corporation (SNC), the global aerospace and national security company owned by Eren and Fatih Ozmen, delivered a prototype crew module for Dynetics' Human Landing System (DHLS), to NASA's Johnson Space Center (JSC). Dynetics is a wholly owned subsidiary of Leidos. SNC is responsible for providing key technologies and system integration of the crew module as part of the Dynetics-led

A team, including an astronomer from the University of Hawaii Institute for Astronomy (IfA), have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object ever observed in our solar system. The planetoid, nicknamed "Farfarout," was first detected in 2018, and the team has now collected enough observations to pin down the orbit. The Minor
