SOLAR SYSTEM

Detailed explanation-1: -The sun’s corona The third layer of the sun’s atmosphere is the corona. Like the chromosphere, the sun’s corona can only be seen during a total solar eclipse (or with NASA’s Solar Dynamics Observatory (opens in new tab)). It appears as white streamers or plumes of ionized gas that flow outward into space.

Detailed explanation-2: -When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can happen only when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

Detailed explanation-3: -The shadow we see while in the path of totality is called the umbra, and the shadow of the surrounding partial eclipse is a penumbra. The shadow from an annular eclipse (when the moon appears smaller than the sun during an eclipse, and so a ring of light is visible around it) is called an anteumbra.

Detailed explanation-4: -A halo is a ring or light that forms around the sun or moon as the sun or moon light refracts off ice crystals present in a thin veil of cirrus clouds. The halo is usually seen as a bright, white ring although sometimes it can have color.
