  Scientists Track Rapidly Growing Sunspot Behind Intense Solar Storms Toward Earth

  A rapidly expanding sunspot has transformed the Sun into a solar flare powerhouse, producing more than 20 mid-level flares and several extreme eruptions in just one day. As the region now faces Earth, scientists are tracking potential radio blackouts, satellite interference, and dazzling auroras caused by incoming solar storms.

  NOAA Issues G2 Solar Storm Watch; May Spark Auroras but Threaten Satellite Signals

  Space weather scientists are monitoring a coronal mass ejection expected to reach Earth around January 2–3, 2026. NOAA forecasts a G2-level geomagnetic storm, which is considered moderate but can still affect satellites, power grids and radio communications. While the event may bring vivid auroras to high latitudes, it also highlights the Sun’s...

  NASA’s PUNCH Watches Comet Lemmon Respond to the Sun’s Powerful Influence

  NASA’s PUNCH mission has captured striking views of Comet Lemmon as it passed close to the Sun in late 2025. The observations show how solar wind and eruptions reshape a comet’s tail, sometimes causing it to break and regrow. The images provide valuable insight into how solar activity affects objects across the inner solar system.
