Millions of stars crown our heads every night, but could you tell them apart? Did you know we don't see the same stars every night and that each season of the year has its own constellations? Teaching children to look at the stars is a good way to get into the astronomy and to begin to know the immensity of the universe.
In Guiainfantil.com we give you some initiation guidelines to the stars.
At first, men had a very different conception of the sky than today, they thought that the stars were attached to a ceiling that enveloped the Earth. Today we know that the stars move at breakneck speedAnd if they seem to us to be still, it is because they are at such a distance that their movement almost goes unnoticed.
However, it is surprising to know that the stars every day they leave 4 minutes before, and that therefore its movement is continuous throughout the year, this is also due to the movement of the earth around the sun; thus, during the autumn months some constellations begin to be seen on the horizon, while others remain hidden.
It is good to know that you don't see the same stars in all parts of the planetRather, we see stars in the southern hemisphere that we will never have the opportunity to observe in the northern hemisphere.
There are some constellations called circumpolar and they never hide; This is because this type of constellation, for example: Ursa Major, is located on the North Pole, so even if the Earth moves around the sun it will always have the constellation Ursa Major above it. The same goes for Cassiopeia, whose huge W shape accompanies us throughout the year.
The constellations are but a group of stars that men have imagined united over the centuries to form gods, animals or objects. Apparently it may seem that the stars are close to each other, however it is not so, rather, some are separated by millions of light years, but from Earth they seem close to us.
Since ancient times, the different civilizations formed with the stars representations of their gods and their legends. The need to explain many natural phenomena that took place on earth and for which they could not find an explanation, made men find stories in the stars that justified them, such as that the rays that fall on the Earth are the rays of Zeus that are released when being transported by Pegasus, the winged horse.
Actually the appearance of the constellations in the sky supposed a kind of celestial calendar that indicated when they had to sow, reap the harvest, orient themselves in the desert or at sea, or when the different seasons of the year arrived.
Our closest star is the sun. It is the most impressive from the earth, but this does not mean that it is the largest, but that the sun is a medium star, something rather insignificant when compared to giant stars like Betelgeuse.
However, lThe brightest star in the sky is Sirius, a binary star, that is, they are two stars together, one rotating around the other. This is in the constellation of Canis Major, one of the hunting dogs of the great giant Orion, and that when it appeared in the sky it meant that the Nile floods began. You will be able to see it very easily during the winter.
