SOLAR SYSTEM

Detailed explanation-1: -Photosphere-The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.

Detailed explanation-2: -The photosphere is marked by bright, bubbling granules of plasma and darker, cooler sunspots, which emerge when the sun’s magnetic field breaks through the surface. Sunspots appear to move across the sun’s disk.

Detailed explanation-3: -It extends for at least 2, 000 km (1, 200 mi.) above the surface. The chromosphere is normally hidden from our view; its light is drowned out by the brilliance of the underlying photosphere. We can observe the chromosphere with special telescopes on satellites or during a solar eclipse.

Detailed explanation-4: -Around the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun’s surface layer, known as the photosphere. Above this lies the sun’s thin atmosphere, which is made up of the chromosphere and the corona.
