Quick forward a decade to 2012, and the rumors of the end of the world have been dispounded, but in 2022, scientists predict a rare cosmic event will occur. But this event seems to be bigger than the end of the world in 2012!
We know that the Earth is simply a speck of dust in the universe, or not even a speck of dust, that could be wiped out by a tiny bit of cosmic "wind", let alone something huge, like the star explosion we're talking about today, a supernova explosion. The consequences of an exploding star are unimaginable to humans. If it happens in our neighborhood, the lightest consequences would be the destruction of the entire solar system. Then what do scientists predict this explosion will mean for our planet Earth? How long is it from us?
In fact, stellar explosions are awesome events, and no other event in nature surpasses these events, known as supernovae, in terms of releasing raw energy. The torrent of neutrinos accompanying the explosion of a single enormous star releases as much instantaneous energy as the rest of the visible universe combined, but what exactly causes a star to explode?
In fact, this is what causes the violent collapse of stars. When a star explodes, weighing tens of times the mass of the sun, it burns rapidly through hydrogen fuel. An explosion begins when a huge star runs out of fuel and collides with another. The core shrinks, becoming hotter and denser, until the ashes from the previous nuclear reaction melt on their own when the hydrogen storage tanks are depleted. The star starts burning helium, carbon, neon, oxygen.
In addition, once ignited carbon, the internal temperature of the star will be close to 1 billion degrees, elevated temperature leads to the formation of a neutrino terrorism and a large number of escape, the neutrino quickly leave stars, to compensate for the energy loss, core or even burn its fuel faster stars hydrogen supply may last about 10 million years, but the helium supply only lasts 2 million years, The carbon supply will only be completed in 2000 years. The last stage, when the core fuses, silicon lasts less than three weeks, because silicon fuses are key to forming the iron-nickel core, which is about 1.5 times the mass of the Sun and sits at the center of the star.39bet-kết quả bóng đá-kết quả xổ số miền bắc-kèo bóng đá -soi cầu bóng đá-đặt cược
The center of the nucleus is extremely dense. It forces electrons into the nucleus. Electrons are the main stressor of the star, and electrons convert some protons into neutrons. Both process eliminates the support pressure of the stars, lead to growing pressure loss, no fresh energy to harness, therefore stars and gravity were continue, and form a huge bang, core for about a quarter of the speed of light in a few seconds or less time to collapse, about the size of the earth core into a star hot dense neutron star, Only 30 kilometers wide, the center gradually stiffens when it reaches twice the density of an atomic nucleus, and, thanks to the repulsive component of the powerful nuclear force, quickly bounces back into the star's interior.
2022 was a special year, in the history of the universe because scientists predict we may witness the whole process of exploding stars, the explosion at the 2022 type is extremely rare, two stars collide, no one has ever seen this kind of phenomenon, as in grand rapids, Michigan, Calvin college, a group of researchers in a study reported that, A binary system could merge, leading to a huge bang.
Scientists are looking forward to the rare opportunity to study the explosion, which will cause a extremely bright burst of light, making it the brightest object in the night sky. A binary star is two stars orbiting each other so close that they share an atmosphere. Looking at star systems will provide valuable clues about how stars live and die, or may point to some still-mysterious force, so which two stars will collide? How long is it from us?
It is understood that the binary system expected to merge in 2022 is KIC-983227. The research team led by Professor Mona has been observing the binary system since 2013. The shift in brightness of KIC 983 2227 sparked a flurry of attention, with one binary star about 40 times larger than the Sun and the other only a third as large orbiting each other because the two stars are close enough to share an atmosphere.
The binary systems continue to fall in orbit until they smash into each other, causing a huge explosion and becoming a single star. Kic 983227 is about 1,800 light-years away, so we have nothing to worry about. If the merger event is similar to the 2008 explosion, it would take about six months to completely achieve 10,000 times brighter, and scientists are currently determining whether their observations can be explained by the presence of a companion star, but quickly ruled out the presence of a third star. The team's next task is to measure the orbit of the companion pair and the purpose of this period is to confirm if it truly is getting shorter over time, suggesting that the stars are getting close to each other and colliding.
Scientists initially estimated that the explosion would occur between 2018 and 2020, but after a fresh round of speculation, the date was changed to 2022, when the burst of light it caused would be bright enough to be visible to the naked eye from Earth, around part of the constellation Cygnus. The unprecedented explosion will be revealed this year!
