Sun Unleashes Strongest Flare of 2025, Causing Global Radio Blackouts
On Nov. 11, 2025, the Sun erupted with an X5.1-class flare, disrupting shortwave communications across Africa and Europe. The flare’s X-rays and UV radiation ionized Earth’s upper atmosphere, causing R3-level radio blackouts. NOAA warned that a coronal mass ejection could reach Earth on Nov. 12, potentially triggering strong geomagnetic storms ...

Sun Shows Signs of Rising Activity Following Decades of Weakening, Study Finds
A new NASA study shows the Sun’s activity has been rising since 2008, reversing decades of decline. The unexpected trend suggests greater risks from solar storms, flares, and plasma ejections. Scientists stress improved forecasting is essential, with upcoming missions like IMAP and SWFO-L1 set to expand space weather monitoring and protection eff...

Scientists Say Solar Flares Are Hotter Than Expected, Could Reach 108 Million Degrees
A groundbreaking study shows ions in solar flares can reach 108 million°F, about six times hotter than earlier estimates. The research explains decades-old mysteries in flare spectra and urges new “multi-temperature” models to better forecast space weather, protecting satellites, astronauts, and communications from hazardous solar storms.

Astronomers Capture Sharpest-Ever Solar Flare Images with NSF’s DKIST Telescope
Astronomers have achieved a major breakthrough by capturing the sharpest images of a solar flare ever recorded, using the National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST). Observed at the hydrogen-alpha wavelength during the decay of an X1.3-class solar flare, the images unveiled hundreds of ultra-fine coronal loops averagin...

Sun Erupts with Triple Solar Flares After Weeks of Silence
After a 22-day period of solar calm, the Sun unleashed three M-class solar flares on August 3–4, 2025, all originating from active sunspot region AR 4168. These moderate flares released intense radiation, capable of briefly disrupting high-frequency radio signals and potentially sparking auroras at high latitudes. Scientists also detected likel...

Massive X-Class Solar Flare Erupts, Causing Widespread Pacific Radio Blackouts
A powerful X1.9-class solar flare from sunspot 4114 erupted on June 19, disrupting shortwave radio signals across the Pacific, including Hawaii. While it caused significant atmospheric ionisation, no coronal mass ejection (CME) followed. The event highlights rising solar activity and hints at more eruptions ahead, potentially impacting communicatio...
