Is a solar flare the same thing as a CME?

Solar Cycle 25 is here, and that means - in the years ahead - more solar flares and more coronal mass ejections, or CMEs. People sometimes use the words interchangeably, but they're not the same thing. Here's the difference.

What are sun pillars or light pillars?

Sun pillars, or light pillars, are shafts of light extending from the sun or other bright light sources under the right atmospheric conditions. They're caused by ice crystals drifting in Earth's air.

New sunspot cycle could be among strongest on record

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.

Watch: 25 years of the sun

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.

Monster sunspot AR2786 swings into better view

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.

The sun is becoming active again

EarthSky community members have captured the giant sunspot region - AR 2781 - currently making its way across the sun's visible surface.

A new method for predicting large solar flares

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.

Solar Cycle 25 is here

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.
