Constellations
What are constellations?
Constellations are patterns of stars in the sky which astronomers use to help them pinpoint individual stars. Most of the constellations were identified long ago by the stargazers of Ancient Babylon and Egypt. Constellations are simply patterns - there is no real link between the stars whatsoever. Astronomers today recognize 88 constellations. The names of most of the constellations are named after heroes and creatures of Greek myth but some of the are named after people and other things. One example of a person is Copernicus. He was a great astronomer. He found out that the world revolves around the sun. The stars in a constellation are named by the letters of the Greek alphabet. i.e. the brightest star is Alpha, the second brightest star is Beta, and so on.
Why do constellations appear different in the northern & southern hemispheres?
Some constellations are visible in the northern hemisphere sky and some of them are visible in the southern hemisphere sky.
