Watch the sun erupt in new images from NOAA’s weather satellite
A space-based telescope has captured new images of the sun that showcase one of our star's fiery outbursts — and Mercury is in the picture.
Tiny plasma jets on the sun drive the elusive solar wind, Europe’s Solar Orbiter reveals
Solar scientists have found tiny, short-lived jets of energy on our sun to be the primary drivers of the solar wind, marking a step toward better understanding our sun's elusive behavior.
NASA’s launching a new sun mission this month: ‘PUNCH is going to see a total solar eclipse’
Scheduled to launch on Feb. 27, NASA's PUNCH mission could revolutionize space weather forecasts, unify the solar corona and the heliosphere, and help improve astronomy techniques.
‘We expect that we will revolutionize how space weather is forecasted.’ NASA’s new PUNCH constellation will map the solar wind in 3D
Scheduled to launch on Feb. 27, NASA's PUNCH mission could revolutionize space weather forecasts, unify the solar corona and the heliosphere, and help improve astronomy techniques.
Gigantic 500,000-mile ‘hole’ in the sun’s atmosphere aims aurora-sparking solar wind at Earth (photo)
The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor geomagnetic activity on Jan. 31.
Invisible ‘flickering’ on the sun could predict potentially dangerous solar flares hours in advance
Images captured by NASA's Solar Dynamics Observatory have revealed that "coronal loops" give off subtle flashes of ultraviolet light before a solar flare, which could act as an early warning system for dangerous space weather.
The sun’s magnetic field will flip soon. Here’s what to expect.
As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.
Scientists turn 3 years’ worth of solar flares into audible sound (video)
The European Space Agency has released an audio-visual representation of solar activity over the last three years, using data from the Solar Orbiter probe.
NASA Solar Dynamics Observatory back online after 2024 data center flood
The spacecraft themselves continued to operate normally in Earth orbit during the outage and "no science data has been lost."
Sun erupts with powerful X1.2 solar flare, causes radio blackouts (photo)
The sun fired off an X1.2-class solar flare on Friday (Jan. 3), triggering radio blackouts throughout parts of the South Atlantic ocean, Africa and South America.
