- NASA races to save Swift telescope from falling back to Earth with daring rescue mission
NASA is partnering with Katalyst Space Technologies to launch a robotic spacecraft named Lift to boost the Swift Observatory into a higher orbit, preventing it from re-entering Earth's atmosphere due to solar activity. The mission aims to extend Swift's operational life and could pave the way for future satellite rescues, including NASA's Hubble Space Telescope.
- Scientists discover towering red auroras reaching deep into space above Japan
Scientists discovered red auroras over Japan reaching unexpectedly high altitudes during mild space storms, suggesting solar activity may be stronger than previously understood. This finding has important implications for satellite safety and space weather prediction.
- Sun unleashes 2 colossal X-flares within 7 hours of each other, knocking out radio signals on Earth
The Sun emitted two powerful X-flares within 7 hours, causing temporary radio signal disruptions across Earth's dayside. The twin eruptions highlight increased solar activity and its immediate impact on communication systems.
