A University of Southampton team has identified a distinct low frequency radio signature that appears when small-scale auroral structures known as auroral beads emerge, providing a new clue to how intense auroral substorms are triggered. Magnetospheric substorms are bursts of activity in Earth's aurora that can rapidly transform faint arcs into bright, dynamic displays stretching across th

Physicists at the National Institute of Standards and Technology have produced the first detailed calculation of how fast time passes on Mars compared with Earth, providing a parameter that future human and robotic missions will need for navigation and communications. They determine that clocks on the Martian surface run on average 477 microseconds faster per Earth day than clocks on Earth, with

Southwest Research Institute (SwRI) has established the Nebular Origins of the Universe Research (NOUR) Laboratory to investigate how the chemistry of interstellar material leads to the formation of planetary systems. The lab, located within SwRI's Space Science Division and led by Senior Research Scientist Dr. Danna Qasim, is designed to connect pre-planetary chemical evolution with the later s

An international team including astronomers from the University of Geneva and the National Centre of Competence in Research PlanetS has used the James Webb Space Telescope to study helium escaping from the atmosphere of the exoplanet WASP-107b. The analysis, published in Nature Astronomy, links this large-scale atmospheric escape to the evolution and present-day properties of the planet. A

Billions of years ago, rainfall on Mars fed rivers that cut valleys, overtopped crater rims and carved canyons, with some flows likely reaching a northern ocean basin on the planet. Researchers at The University of Texas at Austin have now organized these fluvial features into large drainage systems, producing the first global inventory of major Martian river basins and identifying 16 larg

NASA's Perseverance rover identified light-colored rocks in Jezero crater that consist of white, aluminum-rich kaolinite clay. These rocks formed after prolonged exposure to water leached other minerals from parent rocks and sediments. The process required millions of years of rainfall in a humid environment. Perseverance's SuperCam and Mastcam-Z instruments analyzed the kaolinite fragment

For the first time in the history of the International Space Station, all eight of its docking ports are occupied following the reinstallation of Northrop Grumman's Cygnus XL cargo spacecraft on the Earth-facing port of the Unity module. The visiting vehicles now attached are two SpaceX Dragon spacecraft, the Cygnus XL cargo ship, JAXA's HTV-X1 cargo vehicle, two Roscosmos Soyuz crew spacecraft,
