<p>North Americans are in for a celestial treat as a star is set to explode in the coming days. It is part of the two-star system, called T Coronae Borealis (or T CrB) which is located 3,000 light-years away from Earth. It comprises a red giant star and a white dwarf star, both orbiting each other.</p>

<p>Right now, the star system, also known as 'Blaze Star', is not visible from Earth. However, experts say that the explosion will be so bright and enormous that humans would be able to see it for nearly a week without any special equipment.&nbsp;</p>

<p>The scale of the cosmic event can be gauged by the fact that it would take around 57 million years to reach it even if you were flying through space at 35,000mph. Despite being this far, people on Earth will have a front-row seat.&nbsp;&nbsp;</p>

<p>This spectacular occurrence takes place every 80 years, making it a once-in-a-lifetime event.&nbsp;</p>

<p>"It's a once-in-a-lifetime event that will create a lot of new astronomers out there," Rebekah Hounsell, assistant research scientist at NASA's Goddard Space Flight Center, said in a statement.&nbsp;</p>

<p>"It’ll fuel the next generation of scientists."</p>

<p>While one of the stars is a red giant, the other is a white dwarf, with the age difference between them being billions of years.&nbsp;</p>

Much-awaited star explosion is finally here. How to watch it and where to look

<p>The James Webb Space Telescope (JWST) can be considered a cosmic detective which has been on the hunt for the explosive deaths of massive stars which occurred in the early universe.</p>

<p>Till now, the telescope has discovered evidence of 80 new early supernovas. Among these supernovas, they have found the earliest and furthest supernova ever discovered.</p>

<p>This supernova exploded at a time when the 13.8 billion-year-old universe was only 1.8 billion years old.</p>

<p>The team of scientists studied the data collected by the&nbsp;JWST Advanced Deep Extragalactic Survey (JADES)&nbsp;programme for finding this cluster of supernovas, which includes&nbsp;Type Ia blasts.&nbsp;</p>

<p>These kinds of blasts are called "standard candles" by astronomers and can be used for measuring cosmic distances.&nbsp;</p>

<h2><strong>Is JWST working as a supernova discovery machine?</strong></h2>

<p>Before the JWST started operating in the summer of 2022, just a handful of supernovas were discovered which dates back to when the universe was only 3.3 billion years old.</p>

Supernova hunter James Webb spots most distant star explosion

<p>A rare star explosion will occur in our night sky in the coming months, offering stargazers a once-in-a-lifetime chance to witness the phenomenon with the naked eye.

<p>The event will take place later this year and will lead to the shining of a part of the sky for approximately one week. The exact timing of the explosion is unclear. But the American space agency NASA predicts&nbsp;the D-day to be between now and September.</p>

<h2><strong>What happens during the star explosion?</strong></h2>

<p>The forthcoming eruption, categorised as a nova, signifies a rare celestial phenomenon that occurs approximately once every century.</p>

<p>This event happens when a white dwarf star, comparable in size to the sun but collapsed, and a red giant star, nearing the end of its lifecycle and expanding to roughly 74 times the sun’s size, approach each other too closely.</p>
