How did constellations form in the sky?

Answer 1

Constellations are a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure. Modern astronomers divide the sky into eighty-eight constellations with defined boundaries.

Answer 2

They aren't. The stars are arranged more or less at random, and because people are really good at seeing patterns (even when there really isn't any pattern there to see), someone decides that that group over there looks like ... well, whatever.
Constellations aren't exactly "formed," they're really sort of a stellar Rorschach test. The stars are arranged at random (well, more or less at random) and people, because we're REALLY GOOD at seeing patterns even when there is no pattern to see, think they look like various objects.

Answer 3

Constellations are human inventions. Usually the stars that make up a constellation have no relation to each other; they're generally not part of the same cluster (an exception is the Big Dipper; many of its stars actually do belong to a single open cluster.) A very bright star that is very far away may look similar to a dimmer star that is closer; and if we see two (or more) similar looking stars in the same part of the sky, it is not unreasonable to associate them. It is believed that the constellations were originally invented thousands of years ago as an aid for learning the stars so that they could be used for navigation by sailors.

Answer 4

In essentially the same way that a random pattern of paint splotches might look like a particular shape.

Constellations aren't "real" in the sense that they're actual intentional patterns; they're random collections of stars that happened to suggest particular objects to ancient people.

Answer 5

Stars don't really exist as constellations. In fact, the stars that form constellations are millions of kilometres apart from each other, and if you moved closer to them, you would no longer see them as part of a constellation at all.

Constellations are only patterns in the stars that are visible from Earth - just like we sometimes can see patterns and shapes in clouds when we look at them from a particular angle. There is no set form to the constellations - humans just agree on what they look like, and different cultures have created different patterns out of the same stars.

They are only patterns from the point of view of Earth, and if we were looking at the Sun from the perspective of another star, it would probably form part of some other constellation.

Answer 6

The reason for constellations is the fact that the human brain tries to find patterns in

random stuff. That way, it's easier for us to remember what we saw, recognize it later

if we ever see it again, recognize quickly whether something we saw before has changed

since the last time we saw it, and in general avoid being hit by somebody else with a rock,

find something good to eat, and avoid having our foot eaten off by a lion.

Constellations don't exist in nature. The stars are scattered across our sky in no pattern,

at many different distances from each other and with no relationship to each other. But

when human people had nothing else to do at night but lie around outside, chew on a

piece of grass, and look at the sky, they did the same thing with the stars that we do now

with the clouds ... they found patterns of stars that looked like animals, people, and other

familiar things, told stories about them, and generally attached thoughts to the stars that

they could remember. The only difference between the star patterns and cloud patterns

is that the clouds change their shapes in five minutes, whereas the star patterns we

see now are pretty much the same ones that people saw 20,000 years ago.

Answer 7

a constellation is made up of stars to form a picture.
