A study of oppositely charged magnetic field bands, moving in the sun's northern and southern hemispheres, suggests the coming sunspot cycle - Cycle 25 - will be a particularly strong one. This result contradicts an earlier expert forecast, suggesting a weak Cycle 25.
This video, merging more than 2 decades of footage from SOHO cameras, captures thousands of sunspots, flares, and coronal mass ejections breaking out from the sun.
The sun is becoming active again as it enters Solar Cycle 25. This week, scientists' predictions of sunspots were proven via photos from astronomers around the world. Giant sunspot AR2786 can be viewed with proper filters and may create strong flares that reach Earth.
Solar storms pose risks for society, but more accurate space weather forecasts appear to be coming soon. A team of researchers in Japan has developed a physics-based method for predicting large solar flares, including powerful and potentially dangerous X-flares.
The sun has passed from one of its 11-year activity cycles into another. Scientists predict the new cycle - Solar Cycle 25 - will be about as calm as the previous one.
Solar Orbiter swept as close as 50 million miles (77 million km) to our sun's surface. Now scientists are at work testing the spacecraft’s 10 science instruments, including the 6 telescopes on-board. New images, to be released in mid-July, will be the closest of the sun ever captured.
