Rare Nova Explosion Expected: T Coronae Borealis to Illuminate Corona Borealis – NASA Predicts Event Between Now and September

Jakarta –

Astronomers are now keen to welcome this rare event. A new explosion is expected to occur in the coming months.

Note, a nova and a supernova are not the same.

What is Nova?

Novas occur in binary star systems, where the white dwarf star and its companion star orbit each other closely. White dwarfs, the remnants of stars that have spent their nuclear fuel, pull material, mainly hydrogen, from their companion stars.

This material accumulates on the surface of the white dwarf and eventually triggers a thermonuclear explosion. The explosion causes the white dwarf to brighten dramatically, but that does not mean the star will be destroyed. Alternatively, the process could repeat itself if the white dwarf continues to accumulate material.

In contrast, a supernova is a powerful event that marks the death of a star.

When is a Nova explosion?

This nearby explosion represents a rare astronomical event that occurs approximately every century. At the same time, the nova explosion is called T Coronae Borealis or T CrB. This star is 3,000 light years from Earth in the northern hemisphere and is on the verge of a violent explosion.

This event will see T CrB illuminate the constellation Corona Borealis, shining as brightly as the North Star (Polaris) for about a week.

Corona Borealis, also known as the Northern Crown, is a small constellation located in the Northern Hemisphere. T CrB, a repeating nova located in the constellation Corona Borealis, consists of a white dwarf and a red giant star orbiting each other closely.

The exact time of this amazing event is still uncertain. NASA believes it will happen between now and September.

Quoted from Earth.com, NASA predicts that the peak brightness of the nova will allow it to be visible to the naked eye for several days, and with binoculars for more than a week, before it disappears and may not reappear again for another 80 years.

The explosion that ever happened

Unlike supernovae that destroy stars, novae like T CrB do not destroy star systems. Instead, the star cools to its original temperature and restarts the cycle.

History records significant eruptions of T CrB from 1946 and even 1866. Previous records show that it was seen several centuries ago.

In particular, the Reverend Francis Wollaston in 1787 and Abbott Burchard in 1217 reported seeing a bright star in the constellation Corona Borealis, which suggested the earlier appearance of T CrB.
