This nova is on the verge of exploding. You could see it any day now.

Any day now, people will look up and see a distant star exploding.

Although the people of earth will be able to witness this heavenly event as if it just happened, the explosion of destruction occurred about 3,000 years ago, probably during the time of Solomon, who built the first temple in Jerusalem. Through the Iron Age, the Middle Ages, and the Industrial Revolution, blast lighting suffered. the locationNow just to reach the threshold of this planet.

The light shining through the darkness will come from T Coronae Borealis, a star system where the dead A white dwarf star According to , will shine in a brilliant nova. NASA. Astronomers are calling it one of them. Highlights of the year.

This particular stellar remnant is interesting because it periodically experiences explosions. Experts have determined that it explodes every 80 years. This means there are people alive who could have witnessed it. The last explosion was in 1946.. But hardly any adults today will live to see the next.

Here's everything you need to know about this extraordinary event.

What is Nova?

A so-called “nova” is a type of stellar explosion – not to be confused with it SuperNovaThe extinction of a massive star before it collapses into a A black hole or Neutron star.

for a Nova, you need a white dwarf, the desiccated corpse of a dead medium-sized star. If a white dwarf could steal stellar material from a nearby living star, Hydrogen will accumulate. At the surface of the white dwarf, its temperature increases and eventually explodes like a bomb.

A nova doesn't destroy a white dwarf—rather, the explosion throws elements like carbon and iron back into space.

Normally, white dwarfs are too dim to see with the naked eye, but the luminosity produced by this runaway nuclear reaction is enormous. The dead star should be bright The phenomenon quickly acquired the name nova, which means “new” in Latin, because it looked as if a new star had suddenly appeared in the sky, only to return in darker days.

What is T Coronae Borealis?

T is a nova from Coronae Borealis a. Binary star system Our own Milky Way galaxy is about 3,000 light-years away. It is created by a small, Earth-sized white dwarf orbiting a Red giant star – That is, a Sun-like star in its prime years, running out of nuclear fuel.

Mashable Light Speed

Red giants swell to 100 to 1000 times their original size as they approach death. As a red giant sloughs its outer layers, collects white dwarf matter. The Sun, the center of our solar system, is predicted to become a red giant in 5 billion years.

Walter “Will” Goley, a graduate student Harvard Smithsonian Center for Astrophysicstold Mashable that not all novae recur, but T Coronae Borealis, or T CrB for short, is on an interesting cycle.

“Since the mass transfer (from the companion star) is almost constant over many years, basically what that means is that it's going to build, build, build, explode, blow all that mass away, and then all of that. Something is going to start again,” he said.

When will Nova go?

Astronomers believe that T CrB is on its way to going nova. They predict this will happen sometime between now and September 2024. The last nova occurred in February 1946.

“The way we know it's going to happen soon is before the last explosion in 1946, the system got pretty dim, and that's what happened,” said Gole, who is at the Submillimeter Array Telescope in Hawaii. Planning to study the event together. . “Once it was seen that it dimmed, people became alert.”

“Once it was seen that it dimmed, people became alert.”

NASA and other agencies plan to post updates about the sighting, including from NASA universe Account on X, formerly Twitter.

After hitting peak brightness, the nova will continue to shine for a handful of more nights. After that, people will be able to catch a glimpse of it through binoculars for about a week.

Where in the sky will the nova be?

Will appear in Nova Burst. Corona borealisa small semicircular constellation Flanked by Bootes and Hercules If you weren't a scout in the northern sky, you can download an interactive star chart app to your phone to get your bearings.

gave The free NASA appFor example, under its “Highlights” tab is a basic sky view that uses location data to identify large stars. The nova will be somewhere in the region between the mapped stars Vega and Arcturus. Called Gole's favorite app for finding sources. Starwalkwhich may have app charges.

When this happens, it will neither shine nor twinkle, but just appear as a new star where there was none before. The magnitude of the explosion is expected to be so intense that this momentary point of light will be brighter than Polaris, aka The North Star.

Generally, people who live in rural areas have the advantage of looking at the stars. But in this case, a little city light pollution can help narrow the field, and filter out the brightest objects: Nova should be a standout.

It's a once-in-a-lifetime spectacle, and scientists are eager to learn from it.

“Let's say half of all stars are binary stars. That means half of all exoplanets are binary stars. In searching for other habitable worlds, it's important to understand how their host stars behave. are doing,” Gole said. “Obviously, you don't want to live on an exoplanet around a star that explodes every 80 years.”
