There is a funny legend in the north air. The north story of the north is the story of a five-dimensional composition that floats over the year, Kepesus & # 39;
Kepesus is the ancient Ethiopian king (Ethiopia) in Greek mythology. I've been through a lot of hardship because of Cassiopeia. Cassiopeia, whose daughter is blaming for her daughter, said, "The beauty of my Andromeda girl is better than 50 women of water nymphus," and the anger of the Poseidon sea god is being bought. When Poseidon sent a monster's whale to drive Ethiopia to the place of destruction, Kepesus had to sacrifice his daughter. Fortunately, Andromeda, who is almost a monster's food, rescues Medusa and is rescued by Perseus's hero and becomes a wife.
But Poseidon's anger does not stop here, and eventually Cassiopeia hangs up to constitute and continues to go around North Pole. Even today, in the northern air, Cassiopeia, her husband, Kepesus, the daughter of Andromeda, Gen-in-law of Perseus, and whales shine with each other as concepts.
Celestial Kepesus Celestial … Hard & Hard # 39; to be a secret to the evolution of the galaxies
But Kephaus's place was not only the legend. The Astronomy Institute of Korea and Space Science (KAIST) announced on March 13 that it had recently discovered the creation of a hidden star in the Kepesu area as a multi-purpose infrared image system (MIRIS) developed in 2013. This is the first comment that 66 of young stars (stars) under 10 million years old, which corresponds to the age of the universe, lives in the Keepeus area.
Finding a place where a star is born is a mystery in itself, but what does science mean? "This finding helps explain the evolution of the galaxy process," explained Kim Il-jung, senior researcher of the Astronomy Astronomy Observatory Astronomy Group. In particular, the stars that we see are meaningful because they are huge giants, more than 15 times the mass of the sun.
Heavy stars are born and died by that mass and they have a great impact on the galaxy in general. The most representative is the supernova explosion. The heavy stars decorate the end with the energy that the sun will release for 10 billion years at a time. It's supernova. The core of the star contracts and becomes a small neutron star or a black hole. Heavy stars return oxygen, silicon, and iron to the universe that they have accumulated throughout their lives in this process. Kim Il-jung, researcher, said, "The heavy star has a great influence on the galaxy itself through this process, so observing these stars is a good idea to see how our galaxy has changed chemically and morphological. "
Our MIRIS eyes of the sky are 600km above the ground … The first map of the world's detailed chastity
The MIRIS telescope, launched in November of Satellite Science and Technology No. 3, played a big part in revealing Kepesus's secret. Isaac Newton's terrestrial telescope, which has been observing galaxies on the ground, has looked to the expected area. Using this technique, he successfully produced a detailed map of galaxy using Alpha Paschen, the world's first star-emitted hydrogen spectrum, from a heavy star observation at Kepesus.
Dr. Jung Woong-seop, who took part in the research, "Newton telescopes have used H-alffa, which is a relatively short wavelength among the hydrogen spectra, to observe, however, because of the" stellar ejection "where wavelengths are absorbed or dispersed by different substances in outer space There was a limit, "he explained. However, MIRIS was able to have a more detailed image by observing the longer wavelength & Alpha Paschen & # 39; in an outer space rather than on the ground. Younger stars are formed in large, thick clouds of the name & ionospheric zones that use the hydrogen spectrum of these comments.
It is known that MIRIS can observe the entire galaxy because it can observe a wider area than NASA Space Hubble Thesopop that observes the universe in a similar height. Researchers are planning to find more hydrogen ionization areas in the future, extending to the whole of the same. In the meantime, the results of the study were published in the Astrophysical Journal Supplement Series, the international authority on astronomy.
