In recent decades we have witnessed some of the greatest and biggest explosions in our universe. For example, 4.5 million light years away from us. There was this twin star system basically, two supermassive stars revolving around each other. We eventually merged and resulted into a biggest supermassive explosion, aka Ascent 2016 APS. It is perhaps the largest supernova explosion ever seen. The catastrophic explosion that marks the end of a star's life. This event released 10 times the energy that our sun can release in its entire lifetime. However, this explosion lasted only for few months. Let's take another example. About 3.90 million light years away from us in an APS galaxy cluster. In this particular event, a supermassive star fell into the black hole. Basically, it would have lost its track and got trapped into the black hole's gravity while revolving around the black hole. Scientists call this event as a destruction event. The explosion is so big that it can fit 15 Milky Way galaxies in a row in the creator of this explosion. Even this explosion lasted for few months. It is estimated that there have likely been tens of thousands of supernova explosions in our galaxy alone. Where it creates a supernova per 100 Earth years. Supernovas are very common phenomenon. However, all these major explosions only lasted for few months, some event last for few hours or days. Just imagine an explosion lasting for more than 3 years and still going on. Let's get into it. A team of astronomers at Zwicky Trans-In facility in California were doing a survey in nights to find new supernovas and comments. When by chance their search algorithm found an explosion which was greatest and largest than ever witnessed. Dr. Philip Weissman mentions, he became upon this by chance. As it was flagged by our search algorithm when we were searching for a type of supernova. Most supernovae and tidal disruption events only last for couple of months before feeding away. For something to be bright for two years was immediately very unusual. This object is 80-2021 LWX which is about 8 billion light years away from us. This explosion occurred when universe was just 6 billion years old. This explosion was first observed in 2020 and is still being detected by net-over-off telescopes today. Something which happens 8 billion years ago and is still being detected today. Just imagine the size of universe. It's insane. It's more than 3 years and this object is still exploding. Imagine the amount of energy getting released. The shock is about 100 times the size of our solar system so it's absolutely gargantuan. If you've got something that big that twice the temperature of our sun, that's going to glow very, very, very brightly. What is the reason for this massive explosion? When the current theory is that large cloud of gas, mostly hydrogen or possibly thousands of times larger than our sun was sucked in by a supermassive black hole. However, we have not come up with any actual reason for this event. We are getting to know today when an event occurred 8 billion years ago. We don't know today what lies ahead for humanity in the context of the grand scale of the universe. However, considering the huge distance, the 80, 2021 LW explosion is something not to worry as of now. But we don't know what we will find in future.
