How and when to locate the constellations



Find constellations is a stimulus for any beginner, and we've allbeen through it as an adventure and the challenge of the dark skyabove us that we have for any night. The key is to identify the brightest and then jump from star to star as the addresses youhave and set out on this page. Let's start with the challenge
Focus on the sky can be quite daunting at first because of the difficulty in locating start forms and shapes, but in reality it is more difficult to read a road map and a small dose of relaxation. The stars on any night seem to wander slowly through the sky, and also tomorrow night resemble the same. But how to find the way to a point in a sky so vast and crowded with stars? Very easy, areference star and then jump from one star to another.


For people in the northern hemisphere sky has a bright star near the north celestial pole, which is a good place to start.

In the southern hemisphere we place Sagittarius which is located south of Eagle.
Immediately south of Ophiuchus is Scorpio, with its bright red star
Antares and the sharp sting under the right foot of this giant. West of
Scorpion is Libra, to which the ancients designated the name of
Claws of the Scorpion. Continuing westward from Libra, we get the
Virgo constellation with the star Spica.
Another asterism that attracts the viewer's attention when he contemplates
the sky in the months leading up to December is a grouping of three
stars in a straight line. These stars represent Orion's belt. about
10 ° north of Orion's belt we have the bright red star
Betelgeuse, and about 10 ° south of the same belt is perceived bluish star
Rigel. If we follow the line marked by the belt of Orion to the east (or
left when the observer is oriented to the south) will be found
blue-white star Sirius, the brightest in the sky.
To the west of the belt of Orion to find the bright red star
Aldebaran in the constellation Taurus, and a little further west
will reach the open cluster M45 and the Pleiades. Procyon, Sirius (Sirius)
and Betelgeuse form a triangle. But the winter is called Hexagon
are the following stars: Procyon, Pollux, Castor, Capella, Aldebaran,
Rigel and Sirius.
