"Space zombies" will appear in the sky, possibly from tonight

(NLDO) - From now on, a new star with the form of a fiery "zombie" will appear and be easily observed with the naked eye.

According to NASA, the "zombie" is the binary star system T Coronae Borealis (T CrB), consisting of an ancient red giant star and an Earth-sized white dwarf star.

In it, the white dwarf star - which is a stellar corpse - is "eating" its companion like a zombie.

However, because it eats so voraciously, this white dwarf star will "burst its belly" every 80 years, creating a thermonuclear explosion.

The light from the explosion was so intense that even though the pair of stars are 3,000 light-years from Earth, we could still see it with the naked eye. At that moment, it would look like a brilliant new star that had just appeared in the sky.

Since the beginning of the year, scientists have predicted that this white dwarf star will explode at any time during the year. The suspense has been building as two-thirds of 2024 has already passed.

Now, scientists say the cosmic zombie is so full it could explode at any time—today, tomorrow, next week, or any time before the end of the year. However, scientists are almost certain it will explode before September.

Of course you can only see the explosion at night, when it is not obscured by the strong light from the Sun.

According to astronomer Edward Bloome from the Royal Observatory in Greenwich, London (UK), observing the light produced during this event will provide crucial data for scientists to better understand novae and supernovae events.

Nova or supernova are periodic small stellar explosions or complete explosions when the star officially "dies".

The two previous eruptions of T CrB, in 1866 and 1946, were well documented, and there is evidence suggesting that this nova explosion may also have been observed in 1787 and 1217.

In 1217, the German monk Abbot Burchard, leader of Ursberg Abbey, recorded a rare sighting that appeared in the constellation Corona Borealis (also known as the Northern Crown), to which the two aforementioned stars belong.

He noted that: "A great sign was seen"; and described it as shining brightly for many days.

In 1866 and 1946, observations of this binary star system showed its brightness increasing over a period of about 10 years, dimming slightly during a "pre-eruption decline" phase, and then becoming visible to the naked eye from Earth for about a week.
