The northern sky is a funny legend. More than 30 degrees north is the story of the five-dimensional constellation that moves during the year, "Kepesus".
Kepesus is the king of ancient Ethiopia (Aethiopia) in Greek mythology. During my vanity of Cassiopeia I have suffered a lot of suffering. Cassiopeia, whose daughter boasted her daughter, said, "The beauty of my daughter Andromeda is better than the sum of 50 daughters of the water nymph," and the rage of the sea god Poseidon was bought. When Poseidon sent a monster to direct Ethiopia to extermination, Kepesus had to sacrifice his daughter. Fortunately, Andromeda, which has almost become a monster meal, saved Medusa and saved the hero of Perseus and became his wife.
But Poseidon's wrath does not stop here, and eventually Cassiopeia hangs upside down to become a constellation and continues around the North Pole. Even today, in the northern sky, Cassiopeia, his husband Kepesus, the daughter of Andromeda, the proverbial Perseus and the monster whales are conspicuous.
Space Star Cradle of Kepes … A heavy star might be the secret of evolution of galaxies
But it was not just a legend that kept the brush instead. The Royal Astronomical and Space Institute (KAIST) announced on March 13 that it had recently discovered the cradle of a star formation hidden in the Kepes area as a multi-purpose infrared imaging system (MIRIS) developed in 2013. It was the first observation that there are 66 young stars in the Keepeus stars) less than 10 million years old, corresponding to the young age of the universe.
Finding the place where the star is born is a mystery in itself, but what does science mean? "This discovery helps explain the process of evolution of the galaxy," explains Kim Il-jung, senior researcher at Astronomical Astronomy Observatory of Astronomy. Especially the stars we find are meaningful because they are a "massive star" that is massive, more than 15 times the weight of the sun.
Heavy stars are born and dying with this mass and have a big impact on the galaxy as a whole. The most striking is the supernova explosion. Heavy stars decorate the end of the energies that the sun releases for 10 billion years. It's a supernova. The star's core closes and becomes a very small neutron star or black hole. Heavy stars return oxygen, silicon and iron into the universe that has accumulated throughout this lifetime. Kim Il-jung, a researcher, said: "A dense star has a great influence on the galaxy itself through this process, so observation of these stars is a good trace to see how our galaxy has changed chemically and morphologically."
Our MIRIS eyes from the sky 600 km above the ground … The first mapping of galaxies in the world
The MIRIS telescope, launched in November, November 3, has played a big part in revealing the mystery of Kepes. Telescopic telescope Isaac Newton, who was watching the galaxy on the ground, looked into the invisible area. Using this technique, he was able to create an accurate map of our galaxy using the "Paschena alpha", the world's first hydrogen-emitted spectrum, from the observation of the heavy star in Kepesus.
Dr. Jung Woong-seop, who participated in research, said: "Newton binoculars use H-alpha, which is a relatively short wavelength between hydrogen spectra, but because of" interstellar extinction, "in which wavelengths are absorbed or scattered by various substances in the universe There was a limit, "he explained. However, MIRIS gained a more accurate picture by observing the longer wavelength "Paschen Alpha" in the universe rather than on the ground. The younger stars are formed in large, dense clouds called "ionospheric zones" that use the hydrogen spectrum from these observations.
MIRIS is known to be able to observe the entire galaxy because it can observe a wider area than NASA's Hubble Space Telescope observing the universe at similar altitudes. Scientists plan to find other areas of ionizing hydrogen in the future, expanding to the entire area. The results of the study were published in the Astrophysical Journal Supplement Series, the International Office of Astronomy.
