Astronomers track the sun's 11-year cycle by counting sunspots. Also, we're expecting a strong geomagnetic storm and aurora ...

Each solar cycle is reckoned from a solar minimum, essentially when the sunspot number reaches its local low. The number of sunspots increases over the first half of the cycle, peaking at the ...

The sun was well observed during the period of the Maunder Minimum and this lack of sunspots is well documented. This period of solar inactivity corresponded to a climatic period called the ‘Little ...

Solar-driven temperature shifts alter rock properties and underground water movement, potentially making the Earth’s crust ...

Solar maximum is the period of the sun's roughly 11-year solar cycle, or sunspot cycle, when the number of visible dark patches on the sun peaks. During this time, powerful solar flares explode ...

The water cycle is the journey water takes as it moves from the land to the sky and back again. It follows a cycle of evaporation, condensation, precipitation and collection. The sun heats up ...

On November 8th, 2020 the Sun exploded. Well, that’s a bit dramatic (it explodes a lot) — but a particularly large sunspot named AR2781 produced a C5-class solar flare which is a medium-sized ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...
