MYSTERIES IN THE SHIELD CONSTELLATION AND MORE OF STRANGE UNIVERSE

Hello YouTube. I want to tell you about a very interesting, very recent discovery. It has to do with the Scutum constellation. This is the Latin name of a constellation situated close to the celestial equator. As such, it is at least partly visible from both hemispheres in certain times of the year. In English language, this constellation is also known as the Shield. Well, astronomers have recorded something completely unusual in the depths of space. A source has been discovered in the constellation Shield, emitting sharp flashes of radio waves and X-rays every 44 minutes, with a brightness that increases hundreds of times. This behavior does not fit into any of the existing models of stellar activity. The object was designated ASCAP J1831-0911 and was detected using the ASCAP radio telescope in Australia. Its unique characteristics appeared by chance when the orbiting Chandra X-ray Observatory was simultaneously observing the same area of the sky, which recorded bursts in a different range. Coordinated flashes in the X-ray and radio range shocked the researchers. This is the first time such behavior has been recorded in our galaxy. According to calculations, the peak brightness of the object is about 600 times higher than its usual level. Such radiation excludes the version of a radio pulsar, a typical rotating neutron star. It is also not typical of the other LPT objects, whose behavior was previously considered extremely unusual, but still understandable. Now astrophysicists face a new mystery. A phenomenon has been discovered for which science does not yet have an exact definition. Perhaps this discovery will indicate the existence of a new class of space objects or unknown mechanisms of stellar evolution. This information is from the Russian side that covers latest scientific news worldwide, and I do find very interesting information there. And I will tell you once in a while of what they consider to be of interest. For example, this piece of information. An international team of astronomers has made a breakthrough in the study of early universe. As a result of a re-analysis of existing astronomical data, it was possible to detect 25 quasars with a record redshift above 4.6. These objects are among the most distant and brightest light sources available for observation from Earth. Quasars are super bright cores of ancient galaxies in which supermassive black holes actively absorb matter, emitting energy in all ranges from radio waves to x-rays. They serve as a kind of beacons allowing scientists to look into the epochs when the universe was less than a billion years old. This study led by Silvia Velladita from the Max Planck Institute for Astronomy was made possible by extensive optical, infrared, and radio observations, as well as re-checking data from already known surveys. Even well-researched catalogs can hide unexpected finds, according to the authors of this study. Of particular interest were three radio bright quasars, among which one PSO J200-13 may be a laser, a powerful source of alternating radio emission directed directly towards the Earth. A rare representative of the so-called quasars with weak emission lines was also found. Their nature remains a mystery. These discoveries not only expand our catalog of distant objects, but also provide a deeper understanding of the evolution of the galaxies and the growth of black holes in the early universe. So that's what I wanted to let you know today and I'll bring you more interesting news that science gives us regarding our universe, our solar system, planets, and so forth.
