We May Begin to See a New Star in the Sky at Any Time

NASA announced that a faint star system that has not been visible from our planet for many years will soon be visible to the naked eye. T Coronae Borealis (T CrB) This nova explosion, called , was last experienced in 1946 and was seen from Earth.

T CrB is located 3000 light-years away from our system in the constellation Corona Borealis. A binary system consisting of a cold, red giant star and a smaller, hotter white dwarf orbiting each other and becomes visible again periodically. The reason for this is that every in 80 years A red giant ejects material onto the surface of a white dwarf, causing a nova explosion. Experts predict that a new explosion will come.

The star that can be seen at any time will be as bright as the Pole Star

According to NASA’s statement, the brightness of the system is greater than +10 magnitude. +2 magnitude It will drop to . Magnitude, known as magnitude in English, is a term used to measure the brightness value of stars. +10 means it cannot be seen with the naked eye. +2 means bright enough to be seen with the naked eye. As the value decreases, its brightness increases.

The fact that the star has reached this degree means that we can see it very easily from the earth. So much so that, according to scientists, the brightest As bright as the Polar Star, the 48th star will be. Corona Borealis with the star, Between the constellations Boötes and Hercules You will be able to see it in a semicircular shape.

It is not known exactly when T CrB will become visible to the naked eye. However, the explosion between now and September It has been stated that it may occur between So we have the chance to see the star at any time. You can regularly follow the sky at night. When it becomes visible, we will share it with you. Finally, let us note that explosions occurred before in 1866 and 1946.
