NASA's Van Allen Probe A plunged back into Earth's atmosphere this week years earlier than planned after solar-driven drag accelerated its decay. Officials say most of the 1,323-p…
A Mexican physicist warns that repeating solar cycles could make early 2026 a high-risk period for a crewed Artemis II launch, with implications for astronaut safety and mission p…
New SETI research shows space weather can smear and hide narrow alien radio beacons, meaning signals could arrive looking like noise. Scientists want to broaden search methods and…
NASA warns that the 1,300-pound Van Allen Probe A is expected to re-enter Earth's atmosphere today after intensified solar activity accelerated its orbital decay. The agency says …
NOAA forecasts a minor geomagnetic storm tonight that could let people watch northern lights states across 11 northern U.S. states; plan between 10 p.m. and 2 a.m., check real-tim…
NASA has named 6 March 2026 as the earliest possible launch for Artemis II, the first crewed lunar flyby in over 50 years. The 10-day mission will test Orion and SLS systems, carr…
A team at Fudan University built a molybdenum‑disulfide radio system that survived months in orbit and—based on radiation data and modelling—could last 271 years in high‑radiation…
New measurements from NASA's Parker Solar Probe — the spacecraft that flew closer sun than ever — reveal how the solar wind is heated and point to wave–particle processes that rew…
Spacecraft have recorded 'chirping' radio emissions far from Earth’s surface — a discovery that rewrites where and how magnetospheric waves form and raises fresh questions about s…
A powerful coronal mass ejection sent a geomagnetic storm across Earth, producing vivid pink, green and red auroras visible across the UK, Channel Islands and parts of Europe on 2…
Scientists are pushing two complementary approaches — a formation-flying coronagraph and a proposed Moon‑occultation mission called Mesom — to create artificial solar eclipses tha…
Researchers have extended the First Law of Thermodynamics to account for energy conversion in systems far from equilibrium — a formal generalisation with practical consequences fo…
A scientist's guide to the nine most credible, documented hazards of spaceflight — from vacuum exposure and radiation to fires, debris strikes and psychological collapse — and the…
From a crewed lunar flyaround to a long‑awaited Mercury arrival and new heliosphere probes, 2026 will be a pivotal year for missions that test human systems, hunt lunar resources …
Fast solar wind is continuing to buffet Earth's magnetic shield tonight (Dec. 22), raising the chances of visible auroras across high latitudes — and possibly into parts of the no…
NASA engineers are racing to re-establish contact with the MAVEN orbiter after it failed to reconnect following a routine pass behind Mars on 6 December 2025; partial tracking dat…
A vast sunspot complex comparable in size to the active region that preceded the 1859 Carrington Event has appeared on the Sun and is pointed toward Earth, raising questions about…
NASA and space‑weather forecasters have detected multiple X‑class solar flares during the current solar maximum; intense eruptions can disrupt radio, navigation and power grids an…
A faint, hard-to-detect coronal mass ejection swept past Earth on November 20, 2025, nudging the magnetosphere and producing mid-latitude auroras despite leaving little warning. T…
