Taken with seestar s30 pro with solar filter it shows sun spots on the surface of the sun
What It Is
The Sun is the star at the center of the solar system: a massive sphere of hot plasma powered by nuclear fusion in its core. Sunspots are darker, cooler regions on the visible surface where concentrated magnetic fields interfere with heat flow.
History
People have observed the Sun since prehistory, but sunspots became a long-running scientific record after telescopic observing began. Those daily sunspot counts remain one of the longest continuous records of solar activity.
Science Notes
- The Sun contains about 99.8% of the mass of the solar system.
- Sunspots can last from days to months and can range from about 1,000 to 100,000 miles across.
- The number of sunspots rises and falls with the Sun's roughly 11-year activity cycle.
