The Sun

A massive coronal mass ejection erupted from the sun's far side late on Oct. 21, 2025 and was captured by a NOAA coronagraph.

A haunting grin appeared on the sun as bright active regions and dark coronal holes combined to create a jack-o'-lantern face just in time for Halloween.

Four proposed sun-gazing spacecraft, working together, could help speed up space weather warnings by 40%, a new study suggests.

The turning point seems to have been after 2008, which had the lowest amount of solar activity on record.

New research shows that solar flares are six times hotter than thought and calls for updated sun models that could improve space weather forecasting.

Back in 2019, a consortium of scientists predicted August 2025 as the peak of the solar activity cycle. But where are we now?

Solar eclipse maps show crisp lines for the path of totality, but in reality, the edges of the path are fuzzy, jagged and sometimes wrong by hundreds of meters or more

The Solar Orbiter spacecraft has tracked near-light-speed electrons back to the sun, finding two distinct families generated by solar flares and CMEs.

A new NASA-IBM algorithm called Surya could be a major leap in space weather forecasting.
