During this northern summer, in all parts of the world and without the need for a telescope, a cosmic event could be observed “once in a lifetime”. It is one of the type “not going”, which will occur in a small constellation.

This is what NASA announced, Although the exact date on which this event will occur was not revealed, it is known that it would occur in the northern summer or at the latest in the fall.
For Dr. Rebekah Hounsell, a researcher at the space agency, it is about “a once-in-a-lifetime event that will create many new astronomers, giving young people a cosmic event that they will be able to observe for themselves, ask their own questions and collect their own data”.

As they explained, the “Blaze star” is 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 our Sun, and an “ancient red giant.” The latter is losing its hydrogen due to the gravitational attraction of the former.

“Hydrogen from the red giant accumulates on the surface of the white dwarf, causing a buildup of pressure and heat”specific. “Over time, it triggers a thermonuclear explosion large enough to blow up that accumulated material,” he added.

Dr. Hounsell explained that a nova event should not be confused with a supernova. The latter is known as, “a final, titanic explosion that destroys some dying stars,” she said. In the first, the dwarf star remains intact, sending the accumulated material into space in a blinding flash.
