Test your knowledge on the giant ball of burning gas at the heart of the solar system.
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.
X-class solar flares hit a new record in 2024 and could spike further this year — but the sun isn't entirely to blame, experts say
There were significantly more X-class solar flares in 2024 than any other year for at least three decades. The arrival of solar maximum was a key reason for the spike, but other factors were also at play.
'Like they were demon possessed': Geomagnetic super storms are causing tractors to dance from side to side across US farms — and the sun is to blame
Powerful solar storms in May and October painted auroras across large parts of North America. But some U.S. farmers also witnessed unusual activity from their high-tech machinery, which started boogying back and forth as a result of the geomagnetic disturbances.
Scientists finally confirm that solar maximum is well underway — and the worst could still be to come
A surprise announcement from scientists involved in monitoring the solar cycle has finally confirmed that the sun's most active and dangerous phase — solar maximum — is already well underway, and could continue for at least a year.
'Severe' solar storm that hit Earth Thursday could be 'global phenomenon' with auroras as far south as California
A powerful solar outburst hit Earth Thursday, triggering a "severe" geomagnetic storm. Auroras could be visible as far south as California and Alabama, NOAA predicts.
X9 solar flare launched from sun is the biggest in 7 years — and Earth is in the firing line (again)
The sun has unleashed the most powerful solar flare since 2017, just days after it spat out another monster explosion. Both outbursts have launched solar storms that will likely hit Earth this weekend and trigger vibrant aurora displays.
Auroras may paint the northern US tonight as Earth reels from 'strong' G3 geomagnetic storm
Vibrant auroras could be visible as far south as Oregon and Pennsylvania tonight as Earth reels from a "strong" G3-class geomagnetic storm. However, the nearly full Harvest Moon may complicate viewing opportunities.
