The upcoming partial solar eclipse on March 29 is the perfect time to watch the moon hide and then reveal dark patches on the ...

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

A minor geomagnetic storm is forecast for Wednesday March 5. Chances remain strong for seeing the aurora borealis in 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 ...

The Sun's activity typically peaks at solar maximum, but there's an even more dangerous stage it could enter, and with potentially dire consequences.

When solar cycle activity picks up sunspots appear as black areas on the sun's surface. They can be seen through telescopes fitted with solar filters, and even through solar eclipse glasses.

What are solar cycles? What is the solar maximum? The number of sunspots on the sun's surface changes on a fairly regular cycle, which scientists refer to as the sun's 11-year solar cycle.

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 ...

There may be more northern lights – or aurora borealis – sightings this spring. As we near the spring equinox, also known as the vernal equinox, on March 20, the Earth's magnetic field and ...

The UK weather agency issues regular space weather forecasts for both the northern and southern hemisphere. For the northern hemisphere, which is the half of the Earth that lies north of the equator, ...
