Astronomers have just discovered what might be the most powerful flash of all time, a gamma ray burst.
gamma-ray burst was accidentally discovered in the 1960s by the American military satellite . It is likely that it was produced when the giant star exploded at the end of his life and collapsed into black hole , or when the supercritical star wreckage called neutron star collided. In seconds, these explosions release as much energy as the sun releases over its entire 10 billion-year life span.
The flash detected on Sunday was the strongest flash ever observed, releasing 18 volts of energy. Scientists are still analyzing these measurements, but if the results are confirmed, the gamma-ray burst will be the first ever found to carry more than 10 telcos volts of energy.
In all the cosmic disasters that may affect our planet, the attack of gamma-ray bursts is undoubtedly the most extreme. Gamma ray bursts, as they call it, are powerful events that release large quantities of gamma rays. These are one of the deadliest radiations known. If a person happens to approach an object that produces gamma rays, they will be blown to death in an instant. Of course, gamma ray bursts may affect life's DNA, causing genetic damage for a long time after the outbreak is over. If such a thing happened in the history of the Earth, it would likely change the evolution of life on our planet.
If a gamma ray storm hits the Earth, these areas of the Earth will see higher than normal levels of DNA in planets, animals and humans. The good news is that the Earth was blown up by a gamma-ray burst is a very unlikely event. This is because these outbreaks occur so far away that the chances of being hurt by one of them are very small. Nevertheless, they are still fascinating events that draw the attention of astronomers whenever they occur.
At first, the intensity of the flash was confusing astronomers; they thought it must have been produced by a relatively close source. They also initially thought that energy came from X-rays, not gamma rays. Subsequent analysis of the signal confirmed that it was indeed a gamma-ray burst from a source about 2.4 billion light-years away from . Although not entirely nearby, gamma-ray bursts are still the most recent ever.
Although this gamma ray burst is within a safe distance from the earth, a closer gamma ray burst will be catastrophic for our planet. This high-energy flash within thousands of light years of the Earth Earth will strip away the Earth's protective ozone layer and may lead to mass extinction. In fact, scientists believe that one of the largest mass extinction events in Earth's history. The Ordovician extinction occurred 450 million years ago - probably caused by this explosion.
Although the recently discovered gamma ray burst, known as gamma ray burst 221009A, looks 20 times closer to Earth than the average gamma ray burst, it is still far enough to cause more excitement than worry. "It's really an exciting event! This event is nearby, but it's also very dynamic, which means that the radio, optical, X-rays and gamma rays it produces are very bright and therefore easy to observe. So we can study this gamma ray burst with many large and small telescopes around the world and collect a very comprehensive data set when it first brightens and then disappears.
What is a gamma ray burst?
gamma ray burst is a huge explosion in a distant galaxy that emits a powerful group of gamma rays. Stars in space, supernova and its Other objects radiate their energy in various forms of light, including visible light, X-rays, gamma rays, radio waves and neutrino , to name a few. Gamma ray bursts focus their energy on specific wavelengths. Therefore, they are one of the most powerful events in the universe, and the explosions that produce them are also very bright in visible light.
Why we see green rubber
collimated explosion energy means that most of it is focused into a narrow beam.If the earth happens to follow the focus explosion’s line of sight, the instrument will immediately detect a gamma-ray burst. It also actually produces a bright visible light explosion. A gamma-ray burst that lasts longer (lasts more than two seconds) can produce (and focus) the same energy as 0.05% of the sun instantly converts into energy. Now, this is a huge explosion! It is difficult to understand the vastness of this energy. But when so much energy is emitted directly from half of the universe, it can be seen by the naked eye on the earth. Fortunately, most gamma ray bursts are not close to us.
How often does a gamma ray burst occur?
Generally speaking, astronomers detect an outbreak approximately once a day. However, they detect only those radiation that emits radiation in the general direction of the earth. As a result, astronomers may see only a small fraction of the total number of gamma-ray bursts that occur in the universe.
This raises the question about how gamma ray bursts (and the objects that cause them) are distributed in space. They rely heavily on the density of the star-forming region, as well as the age of the galaxies involved (and perhaps other factors). While most seem to occur in distant galaxies, they may occur in nearby galaxies, or even in our own. However, gamma-ray bursts in Milky Way seem to be quite rare.
Will gamma ray burst affect life on Earth?
The current estimate is that gamma ray bursts will occur in our Milky Way or nearby galaxies, about every five million years. However, radiation is likely to have no effect on the planet. It has to happen very close to us to have an impact.
It depends entirely on the beam. Even objects that are very close to gamma ray bursts will not be affected if they are not in the beam path. However, if there is an object in the path, the result can be devastating. There is evidence that nearby gamma-ray bursts could have occurred about 450 million years ago, which could lead to mass extinction. However, the evidence in this regard is still very sketchy. Analysis of
gamma ray burst
What causes Gulu Gulu? For a long time, they remained mysterious. They are so bright that at first people think they might be very close. Now it turns out that many people are very far away, which means their energy is quite high.
Astronomers now know that it takes something very strange and huge to produce one of the explosions. They happen when two highly magnetized objects, such as black holes or neutron stars, collide and their magnetic fields join together. This effect creates a huge jet that focuses on the high-energy particles and photons that flow out of the collision. These jets spanned many light years of space. Think of them as phaser bursts similar to " Star Trek " , just more powerful and almost cosmic.
gamma ray burst energy is focused along the narrow beam. Astronomers say it is "collective". When a supermassive star collapses, it can produce long bursts. The collision of two black holes or neutron stars will cause a short burst. Strangely, short bursts may be less collimated, or in some cases, not highly concentrated at all. Astronomers are still trying to figure out why this is happening.
