The Sun: Abundant Sunspot Activity | NASA’s Solar Dynamics Observatory FriendsofNASA.org: An abundance of sunspot groups are present on the visible solar disk—at least 12 active regions. Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing, or reorganizing of magnetic field lines near sunspots. The southern solar hemisphere has the m

This is the biggest sunspot we’ve seen in almost a decade! 🤩☀️ Sunspots are cooler, darker areas on the solar surface where the Sun’s magnetic field gets especially intense, often leading to explosive solar eruptions. This sunspot was so big that nearly 14 Earths could fit inside it! The eruptions from this sunspot resulted in the historic May 2024 geomagnetic storms, where the aurora borealis, or northern lights, were seen as far south as the Florida Keys.
