What are Stars and Constellations definition/concept

The formation of a star.- A star is created in space when various gases combine by the effect of gravity and by the fusion of hydrogen and helium atoms . Each star has a mass directly relative to its gravity. This means that the bigger the star, the less time it will live (stars that have a lot of mass use more fuel). Stars and Constellations

If the stars are hot, they tend to be bluish in color, whereas if they are cool, they tend to be red. On the other hand, there are also the so-called brown dwarfs, which are considered flaws because they have little light. In this sense, a brown dwarf has the same ingredients as a star, but it doesn’t have enough mass to undergo nuclear fusion.

the constellations

When a set of stars is situated in the sky so that they produce an image, it is called a constellation. It should be noted that the observation of the sky is different depending on the place of observation and the season of the year. Stars and Constellations

Stargazing has been around since antiquity. Thus, the Babylonians, Egyptians and Greeks of the ancient world called constellations the group of stars associated with some supernatural deity . The Greeks named most of the constellations, especially those that are seen from the northern hemisphere.

the constellation of Orion

The most visible of all the constellations is Orion, which can be seen from any point on Earth. His figure combines bright points of light forming the well-known “Belt of Orion”, also called “The Three Wise Men” because there are three prominent stars: Mintaka, Alnilam and Almitak. Stars and Constellations

This view obeys our terrestrial perspective, since if this constellation were observed from space, it could be appreciated that its stars change places , as they are located in distant points of the Earth. The format of Orion resembles a sand clock crowned by two top stars. It is the best known of the entire cosmos and is located near the constellation of the river Eridanus and the constellation of Taurus.

The cloud complex that makes up Orion consists of a gigantic structure of hydrogen, dust, plasma and rising stars. It is located at a distance of 1500 light years from Earth. Stars and Constellations

In Greek mythology, Orion was a hunter, but a scorpion stung him in the heel and ended his life. On the other hand, the three stars of the “Belt of Orion” were already part of Egyptian mythology.
