sun activity

Our sun is less active than other similar stars. Due to black spots and other phenomena, the Sun has a weaker brightness variation.

Cosmic rays come from supernova explosions and the Sun's magnetic activity affects the weather on Earth.

Researchers from the US Geological Survey (USGS) have dismissed the long-held hypothesis that the sun's activity shakes the ground, leading to an increase in seismic activity.

The US Aeronautics and Space Administration (NASA) has captured impressive images that show the sun has produced the strongest flare from the beginning of the year, and temporarily

The US Aerospace Agency (NASA) predicts this year the sun will be the weakest in a century.

Photographs of the sun on March 12 with a telescope show a faint object roughly the size of a planet connected to the sun by a dark colored wire.

The amount of unstable light from the Sun shining on Earth could partly explain Europe's climate changes over the past 1,000 years.
