  Researcher Photographs Giant Solar Tornado and Massive Plasma Eruption at the Same Time

  On August 20, researcher Maximilian Teodorescu captured a rare photo of two dramatic solar events — a giant tornado of plasma rising 130,000 km and an eruptive prominence spanning 200,000 km. Both were shaped by the sun’s unstable magnetic fields. While the prominence did release a CME, it is not aimed at Earth.

  Sun Unleash a 600,000-Mile Filament in Fiery Eruption

  A spectacular 600,000-mile-long solar filament erupted off the sun’s surface in a fiery blast captured on video. While the resulting CME will miss Earth, experts are watching closely as solar activity ramps up toward Solar Cycle 25’s peak. The event underscores the sun’s ongoing volatility and potential for more powerful outbursts ahead.

  Massive X1.1-class Solar Flare Causes Radio Blackouts Across America

  A strong X1.1-class solar flare erupted from sunspot AR4046 on March 28, 2025. The flare caused major radio blackouts in North and South America, affecting high-frequency communications. A coronal mass ejection (CME) followed the flare but is not expected to hit Earth. More solar activity is anticipated from sunspot AR4046 and AR4048, with a 15% ch...

  NASA Reschedules SPHEREx and PUNCH Missions, Now Set for March 7 Launch

  NASA’s SPHEREx and PUNCH missions, originally set for February 27, have faced another delay. The launch, previously rescheduled for March 4, is now expected to take place on March 7 at 10:09 p.m. EST from Vandenberg Space Force Base, California. NASA cited scheduling constraints at the Western Range as the reason for the latest postponement. The ...
