This ultraviolet image of coronal loops on the Sun was taken using the 335 angström channel of the Atmospheric Imaging Assembly telescope on NASA’s Solar Dynamics Observatory. Earth is shown to ...

Scientists studied coronal loops in 50 such regions in the hours before a flare. These coronal loops — flickering arcs of plasma that produce ultraviolet light that can’t be seen by the human ...

Emily Mason, a heliophysicist at San Diego-based research firm Predictive Science, and her colleagues observed coronal loops in magnetically active regions where 50 strong solar flares occurred.

Bright, erratic flashes in coronal loops were observed before powerful solar flares erupted. 'Cosmic trade route': Alpha Centauri and our Sun may be swapping space rocks 'Earth is in real danger ...

The points of light in straight lines proceeding from the main flare site may be the footpoints of large coronal loops tearing away from the sun and the source of coronal mass ejections (CMEs). Solar ...

Strange brightness variations were observed in coronal loops before powerful solar flares erupted. NASA’s Solar Dynamics Observatory captured these fluctuations, hinting at a long-sought early ...

Coronal mass ejections, or CMEs, are dramatic outbursts during which the Sun blasts charged particles into space at incredibly high speeds. These outbursts occur more often when the star is in one ...
