We're about to be able to see explosion of blaze star from Earth after it happened 3,000 years ago

Due to the vastness of space, an explosion that took place thousands of years ago will be observed by scientists now

Wrapping your head around just how huge space is can be a bit difficult, but I'll do my best.

Due to it being so big, a light year is essentially the distance light travels in one year, so when something happens a couple 100 light years away, it means it will take us 100 years to see it in the night sky.

So, with that in mind, NASA is expecting scientists to soon be able to view a cosmic event that happened 3,000 years ago.

In fact, they expect this once in a lifetime event will inspire the next generation of astronomers and scientists.

NASA is expecting between now and September, the world will bear witness to the formation of a ‘new star’ and see a nova explosion in a glorious display.

A nova is the quick, brief explosion from a collapsing star known as a white dwarf, whereas a supernova is the catastrophic death of a large star.

The dwarf star doesn't break apart and continues to release material in a cycle that can last for thousands of years.

So the event won't be as violent as a supernova, and Earth is also a safe distance away to be impacted from the event (phew).

The star we're about to witness an nova explosion from is T Coronae Borealis (T CrB), also known as the Blaze star - and this star explodes every 80 years or so.

It is believed the first recording of the explosion was in 1217.

T Coronae Borealis is a binary system in the Corona Borealis consisting of an aged red giant star and a dead white dwarf star.

As the red giant heats up, it gets more and more unstable, shedding its outer layers that fall as matter onto the white dwarf star.

According to the space agency, the interchange of stuff leads the white dwarf's atmosphere to steadily heat up until it undergoes a 'runaway thermonuclear reaction', which results in a nova.

“It’s a once-in-a-lifetime event that will create a lot of new astronomers out there, giving young people a cosmic event they can observe for themselves, ask their own questions, and collect their own data,” Dr. Rebekah Hounsell, an assistant research scientist specializing in nova events said at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, US.

For a few days, T CrB will be visible with the naked eye, essentially burning bright enough to create a new star in the sky.

So, amateur astronomers, be prepared...
