* Sunspots are areas on the Sun's surface that are cooler and darker than the surrounding areas. They are caused by intense magnetic activity and are associated with strong magnetic fields.
* Spectacular eruptions of gas are called solar flares or coronal mass ejections (CMEs).
* Solar flares are sudden, intense bursts of energy from the Sun's surface.
* Coronal mass ejections (CMEs) are large bubbles of gas and magnetic fields that erupt from the Sun's corona.
Both solar flares and CMEs can release enormous amounts of energy and can affect Earth's atmosphere and technology.
