In a recent statement, the National Aeronautics and Space Administrationbetter known as NASA for its acronym in English, announced that this summer it will be possible to witness from Earth a “once in a lifetime event” that, according to specialists, will attract to the new generation of astronomers.

As explained by the experts, it is the “Blaze star”: a binary system located in the Northern Crown, about 3,000 light years from Earth. It is composed of a “white dwarf,” that is, an Earth-sized remnant of a dead star with a mass comparable to that of the Sun, and an “ancient red giant.” And this last one is losing its hydrogen by the gravitational attraction of the first.

“Hydrogen from the red giant accumulates on the surface of the white dwarf, causing a buildup of pressure and heat” that over time “triggers a thermonuclear explosion large enough to blow up that accumulated material,” explained Dr. Rebekah Hounsell, a researcher at the space agency. This explosion occurs, on average, every 80 years in that system.

This event took the name nova T CrB and was first seen in 1217 in Germany and the last time it occurred was in 1946. Thanks to the patterns, it is known that in September 2024 It would be the new opportunity to witness the event.

What do you have to look for in the sky to see it?

During this event, people should look for the “Northern Crown“, a curve of stars horseshoe shaped west of the constellation Hercules. According to specialists, it is seen much better at night and the ideal is for the sky to be clear. To identify it, you must locate the two brightest stars in the northern hemisphere, Arcturus and Vega, between the two of which will be the point of the explosion. You don’t need a telescope, but you can see it with the naked eye.

Specialists recommend looking for the constellation Hercules.
