Earlier this week, the number of visible sunspots on our home star fell to zero for the first time in 1,335 days. This ...

“The definition of the solar maximum is when the sunspot number is at its highest,” Dr Rachel Howe, a solar physicist at the ...

A solar storm is a catchall term that describes any disturbance in the sun that involves the violent ejection of solar material into space. This can come in the form of coronal mass ejections, where ...

The sun's visible disk has been perfectly free from sunspots for the first time since June 2022, suggesting the current solar cycle might be heading toward its quieter phase.

Solar Cycle 25 has reached its most active phase, bringing stronger solar flares and geomagnetic storms that may affect Earth’s technology.

NASA’s Solar Dynamics Observatory captured an X2.8-class solar flare and a pair of m-flares that preceded it in multiple ...

The sun has unleashed four powerful solar flares towards Earth that could wreak havoc on radios and GPS satellites. The stellar bombardment began on February 1 at 12:33 GMT as the sun fired off a ...

Researchers say a deadly earthquake in Japan and 2023’s most powerful solar flare occurring back-to-back can’t be a ...

Space scientists have announced that the Sun has fired four massive solar flares. The outbursts were captured by NASA’s Solar Dynamics Observatory spacecraft, which monitors our star’s activity for ...

March 2026 could be the best month for the northern lights until the mid-2030s, as celestial mechanics and solar activity combine for potentially potent results.

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...
