Weather of Arabia - Scientists expect a rare cosmic explosion to occur in the Milky Way Galaxy in the coming months, an extremely bright event that is expected to create a new <a href="https://www.arabiaweather.com/%D8%B3%D9%85%D8%A7%D8%AA/%D8%A7%D9%84%D9%8... in the sky for a short period during the night. This event, known as a “NOVA explosion,” is a rare, once-in-a-lifetime opportunity to observe the sky for those living in the Northern Hemisphere, according to NASA. Scientists point out that this type of explosion is uncommon in the galaxy , as reported by the American NBC network. The stellar explosion will occur in a system known as “T Coronae Borealis,” which is 3,000 light-years away from Earth, and includes two stars, one of which is a dead star known as a “white dwarf,” and the other is a “red giant” star that is orbiting. Turn it around. Red giant stars are dying stars, running out of hydrogen fuel in their cores. According to NASA, this is the fate towards which the Sun is ultimately heading.<h2 style=";text-align:left;direction:ltr"> When will NOVA occur?</h2> Any time between now and next September, astronomers expect a nova explosion to occur. Reports indicate that systems such as “T Coronae Borealis” often include two stars that are very close to each other, as hydrogen fuel from the “red giant” constantly flows onto the surface of the “dwarf.” the White". Over time, the pressure and heat due to this process increase, and eventually this can lead to an explosion, according to what the American network reported. <img alt="" src="/sites/default/files/uploads-2020/%D9%8A%D8%AD%D8%AF%D8%AB%20%D9%85%D8%B1%D8%A9%20%D9%88%D8%A7%D8%AD%D8%AF%D8%A9%20%D9%81%D9%8A%20%D8%A7%D9%84%D8%B9%D9%85%D8%B1%20%D8%A7%D9%84%D8%A3%D8%B1%D8%B6%20%D8%B9%D9%84%D9%89%20%D9%85%D9%88%D8%B9%D8%AF%20%D9%85%D8%B9%20%D8%A7%D9%86%D9%81%D8%AC%D8%A7%D8%B1%20%D9%83%D9%88%D9%86%D9%8A.jpg" style="width: 338px; height: 600px;" /><h2 style=";text-align:left;direction:ltr"> Supernova explosion in 1946</h2> Bradley Schiffer, professor emeritus of physics and astronomy at Louisiana State University, points out that the last time the T Coronae Borealis system exploded was in 1946 , and a new eruption is thought unlikely before about 80 years have passed. Astronomers around the world are keen to monitor activity in this system, and when the explosion is detected, the brightest scenes are expected to appear within 24 hours, and the explosion can be visible with the naked eye for a few days before it fades. In research published last year in the journal History of Astronomy, Schaefer discovered two long-lost explosions in this system, one documented by German monks in 1217, and the other witnessed by the English astronomer Francis Wollaston in 1787.
