The world's first galaxy accurate map is over … Heavy stars, galaxies Secrets of evolution

There is an interesting legend in the northern sky. The northern latitude is 30 degrees Celsius, the five-dimensional star of the "Kepesus".

Kepesus is the king of ancient Ethiopia (Ethiopia) in Greek mythology. I have abandoned many difficulties with the Cassiopian tragedy. Cassiopia, proud of her daughter's daughter, says: "My daughter Andromeda beauty is better than the 50 girls of the water nymphaeus" and Poseidon's fury of the sea god has been acquired. When he sent a monster to kill Ethiopia from Poseid, he had to sacrifice his daughter Kepezus. Fortunately, he rescued Andromeda Medusa, who became the monster's food, rescued Perzers and his wife.

But Poseidon's anger does not stop here, and eventually Cescopia becomes the Constellation, at the North Pole. Even today, Cassiopean in the northern sky, husband Kepes, daughter Andromeda, her son-in-law and pirates do not resemble each other.

The celestial cage of the cage … may be a secret of the evolution of the "giant star" galaxies

But it's just a legend that has saved it. The Korea Astronomical and Space Sciences Institute (KAIST) announced on March 13 that it has opened a hidden star cradle in the Kepesu area as a multi-purpose infrared image system (MIRIS) developed in 2013. These observations were the first observation of the Keepeus region, 66 young stars (stars), up to 10 million years old, corresponding to the age of the world.

Finding a Starbed is a mystery, but what is this science? Senior scientist Kim Il-Jun, a astronomers researcher at the Astronomy Astronomy Observatory: "This discovery will help explain the galaxy's evolutionary process. Especially the stars we have found are very important as they are massive, more than 15 times the mass of the sun.

The heavy stars are born and dying of these masses and, in general, have a great impact on the galaxy. It is the most supernormal explosion. Heavy stars finish the sun with instantaneous energy for 10 billion years. This is supernova. The star's core is a very small neutron star or black hole in the nucleus. Heavy stars return oxygen, silicon and iron into the universe that has accumulated throughout this lifetime. Researcher Kim Il-Jun says: "The Galaxy's giant star is greatly influenced by this process, so watching these stars is a good part of knowing how our galaxy changed from a chemical and morphologic point of view."

Korea's Institute of Astronomy and Space Sciences (MIRIS) has developed Infrared infrared telescope MIRIS (Multi-purpose Infrared Ray Observation System) in Korea in 2013. It is considered to be effective for a wider range of observations than the Hubble Space Telescope and the Earth's larger orbit of about 600 km. [사진 한국천문연구원]

The MIRIS telescope, which launched its science and technology satellite No. 3 in November, played a major role in discovering the secret of Kepesus. Isaac Newton, watching the underground galaxy, looked at the invisible area of ​​the earth's telescope. Using this technique, he has been able to create a real map of our galaxy using the Paschen Alfa, the first hydrogen spectrum in the world to produce stars from the heavyweight star in Gepler.

Researcher Dr. Jung Wong-deop: "Newtonian telescopes use H-alpha with relatively short wavelengths between the hydrogen spectrum, but the length of the wave was limited because of the" interstellar disconnection "that was absorbed or dispersed by various substances in outer space," he explained. . Nevertheless, MIRIS was more accurate by observing long-wavelength "Paschen Alpha" in outer space than on the surface. Small stars are formed in large, dense clouds called "ionospheric zones" that use hydrogen spectra from this observation.

MIRIS knows he can control the entire galaxy, because he can see the NASA's space-like space Hubble Space Telescope. Researchers are planning to find ionizing hydrogen fields in the future. The results of the study were published in the additional series Astrophysical Journal, an international astronomical body.
