Stars

The star is the type of astronomical object and consists of its own powered plasma ballast. The closest star to the world is the sun. Many other stars in the naked eye during the night look like a lot of light from heaven. Historically, most celebrities are grouped with astronomy and asterism, and the most obvious ones are their names. Astronomers compile a star catalog that recognizes famous stars and stars. However, not all the stars in the universe, and in addition to our galaxy, the Milky Way does not appear in the naked eye on earth. In fact, most of them do not even see the most powerful telescope in the world.

There are billions of billions of billions of stars in the sky, but about 2,000 stars can be seen through the naked eye of a nightless night. All the stars are very large. They are far from us, so they seem to be less. The sun shines in the nighttime beaches are constantly increasing and decreasing. The stars classify the physical properties, size, color, clarity, and temperature. The star on the north pole directly around the stars and stars is the star of the star. Indian name of the Polar stars Dhruva Tara. White poles are located in the sky and do not change their positions. All stars except the North Star seem to be moving from left to right.

Observing places with different geographical locations with two stars, the height / orientation and azimuth angle of the stars are different. The height and direction of the star indicate the position of the star when it is observed. Due to the daily movement of space objects, the height and orientation of stars change every time.

For hundreds of years Polaris was known as a guide to the Arctic. Lodestar, Steering Star, Pivot Star, Ship Star, and so on. Polaris is often used as a symbol of homeostasis and loyalty. In ancient times, it was thought that it was the spinning earth – just as if there was a single axis actually inserted through the earth into the sky.

Astronomers estimate the distance of the north star to 430 light years. Given the distance, Polaris must be a pretty bright star. Polaris is a yellow superstar shining in 2,500 suns, according to star favorite Jim Kohler. Polaris is also the nearest and brightest Cepheid variable star – used by astronomers to compute the distance between stars and galaxies.

Scientific Academy of Sciences. The only point we can see for Polaris is actually a triple-star system or a three star around the center. The first star, Polaris A, is about 6 times the mass of the sun. Nearby satellites Polaris Ab rolls 2 miles from Polaris. According to more detail, the third Polaris B is located approximately 240 kilometers from Polaris A.

It may not be new for you, is she? But do you know that Polaris is not a star, but a system of three stars? They are superstar Polaris A, short star Polaris Ab, and dwarf Polaris B, they are all constrained by gravity and rotate around Polaris A. Cepheid variable stars are used to determine the distance to the galaxy.

Polaris is a small star consisting of a pair of orbital pairs with a small star (Polaris Aa, a yellow superstar), Polaris B (founded in August 1779 by William Herschel). It was once thought of as two more distant components – Polaris C and Polaris D -, but these components have been proven not physically connected to the Polaris system.

Some people know how to jump to Polaris Polaris using Big Dipper’s pointer star as shown in the sky map below. Big Dipper and Cassiopeia’s handles are shining on both sides of Polaris, so any Star of North Star definitely points to Cassiopeia through the fictional line of Polaris.

The most important thing is to find the Polaris Polaris using the Big Dipper. This is accomplished by attaching two bright stars to the outer edge of the Big Dipper bowl. Since the two stars – Dubhe and Merak – are always pointing to Polaris, they are called “pointers”. By drawing a line on imagination, you can stretch between two stars at a distance of about 5 times the distance between two stars.

Ken Christensen captured these glorious stars around the Polaris Polaris. He says, “For the most common and often the most spectacular stars, you want to join the images to find the Polaris and lay them horizontally to center them. I think there is a good chance. “

To find the famous star Polaris near the North Pole poles, look for a famous constellation model called Big Dipper or Ursa Major Plow. At the end of the Big Dipper’s “dish” draw a line connecting the stars, then extend to a length of 5 times its length and reach the Polaris. This is the brightest star in Ursa Minor or Little Dipper so you can not miss it.

A group of stars that everyone knows familiarly is Big Dipper, but it is only a part of a configuration called Big Bear. There is also a small Big Dipper. The grip of Little Big Dipper is a star called North Star, but in addition to being called North Star, it looks bright, so it stands out even in the sky. With the naked eye it is the brightest and most visible in the sky.

Some people know how to jump to Polaris Polaris using Big Dipper’s pointer star as shown in the sky map below. Big Dipper and Cassiopeia’s handles are shining on both sides of Polaris, so any Star of North Star definitely points to Cassiopeia through the fictional line of Polaris. Cassiopeia is the queen of ancient Greek mythology. According to legend, she boasted that she was more beautiful than the sea fairy called Nereido. She boasted of Poseidon, the god of the sea Poseidon, and he sent a sea monster whale to the kingdom. In order to appease this monster, Princess Andromeda, the daughter of Cassiopeia, was tied to the rock in the sea. When a hero Perseus overlooks her from Pegasus Pegasus, a whale is swallowing her. Perseus rescued the princess and everyone lived happily.

You may know that the starfish is starfish, and the name of the star is usually well-known. However, starfish is not a real fish. Starfish such as sea urchins and sandbags have no backbones, so they will be a group of invertebrates. Fish have bones that make them a vertebrate. I got?

Constellations are similar to the national map. Each star is in the middle of a certain star, but stars between stars (informally). The star of Pegasus Square near Andraseda and Pegasus is close to Cassaspaope and Alfasaz. The star is Andromeda’s head. Her legs were opened by two curved lines (like a girl’s skirt) and extended her back under Cassioleep. (Cassiopeia was originally from Andromeda.)

The Andromeda galaxy will start to collide with our Milky Way Galaxy. Amazing gravity dance of trillions of stars from the Andromeda galaxy, and the Milky Way has 200 billion stars. Since the distances between stars are very far, it is unlikely that two stars collide in this process.

To find the galaxy, count the three stars according to Andromeda’s head and the bottom curve. Then count it from three stars. The Galactica is located on the right of the third star. As noted above, the galaxy is like a glossy star with a naked eye and is like a small ellipso cloud through a telescope. The following diagram shows Pegasus, Andromeda’s situation in the east.

Blue stars are usually hot and young stars, but blue stars in the Andromeda Galaxy are aging as stars of the Sun and their outer layers are removed and red hot stripes. These celebrities are spread over the center of the galaxy and overlap with ultraviolet rays.

The difference in the galaxies is due to which wavelength star is the brightest at the wavelength of light and ultraviolet rays. Ultraviolet images of galaxies mainly show gas clouds including newly formed stars. It is several times the mass of the sun and is strongly illuminated under ultraviolet light. In contrast, the visible light image of the galaxy mainly shows the yellow of the older star and the red light.

The star of the 7500 light-years-old Wolf-Reith star is an astronomer in the 104-star system. Witch stars may also be able to generate high-energy gamma rays. This gamma burst (gamma burst) is the most energetic phenomenon of all the stars.

GJ 237 is a Luyten star, which is an unusual red dwarf star on the Little Bird constellation. These are the twelve light years in the world, which are invisible to naked eyes. This star is close to Ponsi’s big star, just like Venus in the sky.

Some of the more conspicuous stars are Gamma Coronae Australis, a pair of yellowish-white stars 58 light-years away from the earth, and it has been circling every 122 years. Since 1990, two stars can be regarded as independent from a 100 mm caliber telescope; they are 1.3 arcs apart at a 61 degree angle. Their visual intensity is 4.2, each component is F8V dwarf with a size of 5.01. Its spectrum type is F4VFe – 0.8 +.
