Question

only 10 lines paragraph on topic the night sky​

Answer 1

Answer:

• At night we see stars in a dark sky, and these stars make up our galaxy, the Milky Way.
• The Milky Way is made of a huge number of stars.
• It is associated with astronomy from Earth.
• Without an atmosphere the sky appears black, as evidenced by the lunar sky in pictures taken from the moon.
• But even a black sky has some lightness.
• At night, the sky always has a faint color, called "skyglow" by astronomers.
• The phenomena occur when four types of slow-moving, high-altitude atmospheric waves merge over a small region and, in turn, temporarily drive a 10-fold-or-stronger brightening of an ever-present glow in the upper atmosphere
• Natural light sources in a night sky include moonlight, starlight, and airglow, depending on location and timing. 
• Aurorae light up the skies above the polar circles.
• The night sky and studies of it have a historical place in both ancient and modern cultures.
