In its website, NASA explained that the star is the object of the universe that usually has the ability to create nuclear fusion reactions independently. Star consists of several elements, the main constituent, namely hydrogen and helium. That is why, they can produce their own light, for example the star of Sun in our solar system.<\/p>\n\n\n\n
Well, if viewed from the Earth, a collection of stars in outer space is certainly very difficult to be calculated. Moreover, there are more than 400 billion stars in the Milky way Galaxy that consists of the type, size, and time of birth are different. But, in general, several groups of stars can be classified based on the pattern or shape.<\/p>\n\n\n\n
In the world of astronomy it is called a constellation or cluster of stars. There are more than 80 constellation of stars that can be observed from the Earth using a special telescope in specific zones. However, scientists and academics believe that the cluster of stars in the universe amounts to almost without limit.<\/p>\n\n\n\n
So, this is it ten constellations with the most popular form. Oh, yes, the cluster stars is not for fortune-telling, yes. Let’s be listened to!<\/p>\n\n\n\n
1. Hydra<\/p>\n\n\n\n
Reported in the pages Britannica, the constellation Hydra is a cluster of stars in the sky to the south and stretches from 5 degrees north to 30 degrees south. In general, this constellation form a group of stars that are elongated like a snake. Oh, yes, if viewed from the Earth, the constellation of Hydra was one of the biggest and he is most concentrated if observed from countries south of the Earth.<\/p>\n\n\n\n
The great constellation has 17 main stars, in which thirteen of which have planets. Well, in the constellation of Hydra there are also the brightest star named Alphard and is 177 light-years from Earth. Alphard itself has a mass of three times the Sun and his age is still quite young, which is about 400 million years. So, if the clear night sky, you can observe the cluster is using a telescope.<\/p>\n\n\n\n
2. Crux<\/p>\n\n\n\n
Crux is a cluster of star-shaped cross and can be clearly seen in the southern hemisphere. According to the Star Registration, the formation of the constellation Crux has been found by the people of Europe in the 15th century. Constellations is one of the smallest and was originally considered to be one of the Centaurs.<\/p>\n\n\n\n
Well, the biggest stars and brightest in the constellation of Crux is Acrux or Alpha Crucis. Though small, this constellation be home for 19 stars that almost all of them have planets. If you want to see it clearly, the month of May is the right time. He could be observed at latitudes between +20 degrees and -90 degrees.<\/p>\n\n\n\n
3. Pegasus<\/p>\n\n\n\n
Pegasus is one of the constellations of the most famous in the world of astronomy. Written in the page Space, the constellation Pegasus is a collection of the most prominent stars in the sky north of the Earth. If you’re in the northern hemisphere, we can see this constellation in late summer and continuing through autumn.Cluster Pegasus also contains the Messier objects (M15), which is a collection of objects of space in the form of asteroids and dwarf planets, which is 34 thousand light-years from Earth. Well, interestingly, M15 or Messier be a cluster of the most populous in the Milky way Galaxy.<\/p>\n\n\n\n
4. Canis Major<\/p>\n\n\n\n
Canis is the Latin name for the family of a canine species, including wolf, coyote, and others. Well, the naming is also used as one of the constellations, namely Canis Major. By page Nine Planets, constellations, it has been known since the era before ce or about 3 thousand years ago.Canis Major can be seen quite clearly in the southern hemisphere at latitudes between +60 degrees and -90 degrees. Oh, yes, in this constellation there are seven main stars that accommodate some of the planets. One of the biggest stars in the galaxy we are in Canis Major and is called VY Canis Majoris. This star-sized 1.420 times larger and 270 thousand times brighter than the Sun.<\/p>\n\n\n\n
5. Aquila<\/p>\n\n\n\n
Literally Aquila can also be interpreted as eagle. Universe Today explains that the constellation Aquila is already included as one of the constellations in the 2nd century Ad by a Greek astronomer named Claudius Ptolemaeus. Within 6,500 light-years from Earth, this constellation<\/p>\n\n\n\n
One of the brightest star in Aquila is Altair. Because of the cluster of stars is located along the Milky way Galaxy, then he will be more concentrated if it is seen in the northern region of the Earth in the summer time. Well, the position is located at latitudes between +90 degrees and -75 degrees.<\/p>\n\n\n\n
The grouping of stars called the constellation was already done by humans since ancient times. Typically, this is done for certain purposes, for example the science of astronomy, direction, and even associated with the legend in a particular culture.<\/p>\n\n\n\n
