Look up at the Sky Day takes place on April 14, 2021. The day is a goof opportunity to go outside and see what’s going on above you. Maybe there is an airplane, the shining sun, funny clouds or a meteor on it's way. You can also try to look for our milky way in the night.
The sky, also known as the celestial dome, commonly refers to everything that lies a certain distance above the surface of Earth, including the atmosphere and the rest of outer space. During daylight, the sky appears to be blue because air scatters blue sunlight more than it scatters red. At night, the sky appears to be a mostly dark surface or region scattered with stars.
During the day, the Sun can be seen in the sky, unless obscured by clouds. In the night sky the moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning and precipitation can also be seen in the sky during storms. Birds, insects, aircraft, and kites are often considered to fly in the sky. (With material from: Wikipedia)
