The Sun is the star at the center of our solar system, a massive sphere of hot plasma fueled by nuclear fusion. It emits the energy that sustains life on Earth and shapes our solar environment. On its surface, sunspots often appear—these are cooler, darker regions caused by intense magnetic activity that temporarily inhibits convection. Sunspots usually form in groups and follow an 11-year solar cycle, growing in number and size during periods of high solar activity. Observing the Sun safely reveals dynamic features like sunspots, flares, and prominences—offering insight into the complex behavior of our nearest star.
