The National Aeronautics and Space Administration (NASA by its acronym in English) has announced that a phenomenon will be observed around the world this northern summer. “Once in a Lifetime”. It is a type of “nova” that occurs in a small galaxy. According to experts, it will attract a new generation of astronomers.
This is stated in a press release issued by NASA The exact date on which this event occurs is unknown, but it is likely to be in the northern summer or autumn. Space Agency researcher Dr. Rebecca Hounsell said, “This is a once-in-a-lifetime event that will create many new astronomers, giving young people a cosmic phenomenon they can observe for themselves, ask them their own questions and collect their own data.”
As they explained, “Blaze Star” is a binary system located in the northern corona about 3,000 light-years from Earth. Tierra. It consists of a “white dwarf,” an Earth-sized remnant of a dead star with a mass comparable to our own. Sol, and an “ancient red giant.” The latter loses its hydrogen due to the gravitational attraction of the former.
“Hydrogen from the red giant accumulates on the surface of the white dwarf, creating pressure and heat”Specific. “Over time, it triggers a thermonuclear explosion large enough to blow up the accreted material.”he added.
Dr. Hounsell explained that a nova event should not be confused with a supernova. The latter, he said, is “a final, titanic explosion that destroys some dying stars.” First, the dwarf star remains intact, sending accreted material into space in a blinding flash.
This phenomenon has already occurred at other times and experts have pointed out where to look for it
The nova de crpi, an event known to occur this year, was first observed in 1217. Germany And the last time it happened was in 1946. Thanks to the patterns, it is known that September 2024 will be a new chance to see the event.
What is there to seek in heaven?
During this event, people should look for the “Northern Crown,” a horseshoe-shaped arc of stars west of the Hercules constellation. According to experts, it is very good at night. To identify it, you need to find the two brightest stars in the Northern Hemisphere, Arcturus and Vega, which will be the point of explosion between the two. You don’t need binoculars, but you can see it with the naked eye.
Despite the anticipation, September may pass without the event being showcased. “Successive novae are unpredictable and inconsistent”, I’m Koji Mukai, an astrophysicist at NASA. “Just when you think there couldn’t be a reason why they follow a certain pattern, they do., and as soon as you start believing in repeating the same pattern, they completely withdraw from it. Let’s see how T CrB behaves,” he said.
How common are novae explosions?
According to NASA, astronomers believe that the frequency with which a nova explosion occurs is not repeated. They explain that on average every 80 years or so by the end of the century Two or three supernovae occur in our galaxy milky way.
However, they explain that the universe consists of many galaxies. “A few hundred supernovae are observed every year outside our galaxy. Space dust blocks our view for most people,” says NASA.
How bright can they be?
Additionally, novae are events that produce a series of lights.
“These spectacular events can be so bright that they can eclipse their entire galaxies for days or even months. “They are found throughout the universe,” says NASA.
