A new mission designed to better understand the heliosphere will be the first to map in three dimensions how the solar corona becomes the solar wind.
A strong X-class solar flare erupted from the sun on Sunday, Feb. 23, creating radio blackouts across parts of the Pacific Ocean.
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.
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.
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.

The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor geomagnetic activity on Jan. 31.
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.
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.
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.
