Eighteen years after NASA's Stardust mission returned to Earth with the first samples from a known comet, the true nature of that icy object is coming into focus. Stardust collected material from Wild 2, a comet that likely formed beyond Neptune and currently orbits the sun between Mars and Jupiter. Painstaking analyses of the microscopic samples, recently described in the journal Geochemi

The SpaceX launch of the private Axiom-3 mission to the International Space Station was scrubbed until Thursday, the company said on social media just before noon on Wednesday. The flight, the third private industry flight carrying four astronauts the orbiting laboratory was scheduled to blast off late Wednesday afternoon. "Now targeting Thursday, Jan. 18 for [the] launch of the

Windswept piles of dust, or layers of ice? ESA’s Mars Express has revisited one of Mars’s most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometres below ground – the most water ever found in this part of the planet.

ESA astronaut and commander of Expedition 70 Andreas Mogensen has some advice for Marcus Wandt, ESA’s first project astronaut, who will join him on the International Space Station on his Muninn mission. It will be the first time two Scandinavians are in space together, which fits perfectly with their mission names, Huginn and Muninn.

Nearly 75 percent of the U.S. could experience damaging earthquake shaking, according to a recent U.S. Geological Survey-led team of 50+ scientists and engineers. This was one of several key findings from the latest USGS National Seismic Hazard Model (NSHM). The model was used to create a color-coded map that pinpoints where damaging earthquakes are most likely to occur based on insights from se

Diamonds could form in the relatively shallow interiors of planets like Neptune and Uranus and travel downward, driving the ice giants' magnetic fields, according to new research from an international team of scientists including Carnegie's Alexander Goncharov and Eric Edmund. Published in Nature Astronomy, the SLAC National Accelerator Laboratory-led team's findings used the European XFEL

"Zwitterionic" might not be a word you come across every day, but for Professor Patrick Doyle of the MIT Department of Chemical Engineering, it's a word that's central to the technology his group is developing to remove micropollutants from water. Derived from the German word "zwitter," meaning "hybrid," "zwitterionic" molecules are those with an equal number of positive and negative charges.

The powerful gravity fields of black holes can devour whole planets' worth of matter - often so violently that they expel streams of particles traveling near the speed of light in formations known as jets. Scientists understand that these high-speed jets can accelerate these particles, called cosmic rays, but little is definitively known about that process. Recent findings by researchers u

A unique "passenger" is joining an upcoming mission to the moon. In 2026, physicists are planning to operate a radio telescope on the far side of the moon-an unforgiving environment that poses tremendous challenges for research equipment to survive, but also the promise of enormous scientific payoff. Called LuSEE-Night, the project aims to access lingering radio waves from the universe's ancient
