Ganymede aurora study links moon and Earth space weather
London (SDX) Feb 25, 2026 New observations of Jupiter's largest moon, Ganymede, reveal that its auroras share detailed structural similarities with auroras on Earth, suggesting that the physical processes that generate these lights may be universal across different types of celestial bodies. A team from the Laboratory of Atmospheric and Planetary Physics (LPAP) at the University of Liege has used NASA's Juno spacecraft to resolve, for the first time, fine-scale features in Ganymede's auroras, which develop in the moon's th ... read more |

NASA's IXPE Measures White Dwarf Star for First TimeHuntsville AL (SPX) Jan 05, 2026 For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarization Explorer) to study a white dwarf star. Using IXPE's unique X-ray polarization capability, astronomers examined a star ... more 
Solar probes follow hyperactive sunspot region through three full rotationsZurich, Switzerland (SPX) Jan 06, 2026 The sun rotates about once every 28 days, so active regions on its surface are usually visible from Earth for only around two weeks before they move out of view behind the limb. Ioannis Kontogiannis ... more 
Satellite and model fusion boosts China solar radiation forecastsTokyo, Japan (SPX) Dec 31, 2025 The intermittent output of solar power creates challenges for grid operators who must keep supply and demand in balance.

Proba-3 mission closes gap in inner solar corona monitoring
Berlin, Germany (SPX) Dec 19, 2025 Proba-3 has spent its first year in orbit generating more than 50 artificial solar eclipses, giving scientists sustained access to the inner solar corona that previously could only be studied intermittently during brief total eclipses on Earth. The two-satellite ESA mission is designed to supply the missing observations between the solar disc and the well-studied outer corona, and recent data confirm that it is now routinely filling this longstanding observational gap. Launched in December 2024, t ... read more 
NASA's Parker Solar Probe Spies Solar Wind 'U-Turn'Greenbelt MD (SPX) Dec 14, 2025 Images captured by NASA's Parker Solar Probe as the spacecraft made its record-breaking closest approach to the Sun in December 2024 have now revealed new details about how solar magnetic fields res ... more |
