Is the Death Star ready to attack? and got the best answer
Answer from Alexey First...[guru]
There are a lot of incredible things in the Cosmos, but the world is moving according to the Providence of the Creator, in the 3rd Book of the Prophet Ezra there are such words. -
the time will come and all humanity will lie dead - and Christ...
This is said about distant times, when a person from the material, having acquired perfection through evolutionary development. will ascend to the spiritual level of development. That is, the world will not live according to the flesh, but in the Kingdom of Heaven, because man was created in the image and likeness of the Creator.
It’s true that people don’t think about their guidelines and goals, while they waste their lives in the hustle and bustle, which is as necessary for development as nutrition...
As for the Supernova Explosion and gamma rays - here you are right - they will probably bring destruction to the Earth.
For 250 million years Solar system with the planets, where our Earth is, makes one revolution in Our Galaxy around its center in the Milky Way region. During this REVOLUTION, the Earth and all living things fall into the zone of hard cosmic radiation, where no life is possible, especially BIOLOGY...
Perhaps it is this Supernova explosion that will interrupt the next evolution on our Earth.
About 20 civilizations have most likely already suffered this fate... Over the 5 billion years of the Earth’s existence, we have made a revolution around the center of the Galaxy 25 times.
And our Galaxy is included in the Local Cluster, it is included in the Virgo Cluster, then in the Local Supercluster.
The world is big...

Hello! Here is a selection of topics with answers to your question: Is the Death Star ready to attack?
Yule, called the death star WR 104, was discovered eight years ago in the constellation Sagittarius. It circles "every eight months, with the precision of a space chronometer," says astronomer Peter Tuthill of the University of Sydney.
At the heart of this fiery cosmic spinning top are two stars revolving around each other. In such mutual rotation, flashes of flowing gas escape from the surface of the stars and collide in the intermediate space, gradually intertwining and twisting the orbits of the stars into rotating spirals.
Direction of the death star's rotation axis WR 104
Both heavy death stars in WR 104 will one day explode as a supernova. However, one of two stars is an extremely unstable Wolf-Ray star in the last known phase of the life of heavy stars before going supernova.
“Astronomers consider the Wolf-Rae death stars to be ticking bombs,” explains Tuthill. “The star's fuse is almost - from an astronomical point of view - blown, and it could explode at any time within the next few hundred thousand years.”
When Wolf Raye goes supernova as a death star, it "could shoot out a massive burst of gamma rays in our direction," Tuthill says. "And if there's a gamma-ray explosion like that, we wouldn't want Earth to get in the way."
Since the initial blast wave will travel at the speed of light, there will be nothing to warn of its approach.
In the line of fire
Gamma ray bursts are the most powerful explosions known to us in the universe. In a time from a few milliseconds to a minute or more, they can release as much energy as our Sun did during its entire 10 billion years of existence.
But the creepiest thing about this Yule- is that we see it as an almost perfect spiral, according to the latest images from the Keck telescope in Hawaii. “So we can only see the binary system when we are practically on its axis,” explains Tuthill.
Unfortunately, the emission of gamma rays occurs directly along the axis of the death star system. In fact, if a gamma ray burst were to occur one day, our planet could be directly in the line of fire.
“This is the first object we know of that can fire a burst of gamma rays at us,” says astrophysicist Adrian Melot of the University of Kansas at Lawrence, who was not involved in this study. “And the distance to the system is frighteningly close.”
The Death Star is approximately 8,000 light-years from Earth, about a quarter of the way to the center of the galaxy Milky Way. While this seems like a long distance, "earlier studies have shown that gamma ray emissions could be detrimental to life on Earth at this distance," Tuthill says.
Possible scenario
Although a spinning top cannot blow the Earth to pieces, it can lead to mass destruction and even the complete disappearance of life on our planet.
Gamma rays will not be able to penetrate deep enough into the Earth's atmosphere to burn the soil, but they will be able to chemically alter the stratosphere. According to Melot's calculations, if the death star WR 104 shoots at us with an ejection lasting about 10 seconds, the gamma rays will deprive us of 25 percent of the ozone layer that protects us from harmful ultraviolet rays. By comparison, human-caused depletion of the ozone layer, which created "ozone holes" over the polar regions, reduced the ozone layer by only 3 to 4 percent.
“Everything will be very bad,” says Melot. - Everything will start to die out. The food chain could collapse in the oceans and there could be an agricultural crisis and famine."
The release of gamma rays can also lead to the formation of sun-obscuring fog and acid rain. However, a distance of 8,000 years “is too great for the darkening to be noticeable,” says Melot. - I would say that in general there will be less sunlight by 1-2 percent. The climate may cool down a little, but it shouldn’t lead to a catastrophic ice age.”
The danger of cosmic rays
What is unknown about gamma rays is how many particles they spew out as cosmic rays.
“Typically, gamma ray bursts occur so far away from us that the magnetic fields of the universe will pull away any cosmic rays we might observe, but if a gamma ray burst occurs relatively close, all the high-energy particles will rush through the galaxy’s magnetic field and hit to us,” says Melot. “Their energy will be so high that they will arrive almost simultaneously with the light stream.”
“That part of the Earth that turns out to be facing the flow of gamma rays will experience something similar to a nuclear explosion; all organisms can suffer from radiation sickness,” Melot adds. “Moreover, cosmic rays can exacerbate the effect of gamma rays on the atmosphere. But we simply don’t know how many cosmic rays are emanating from gamma rays, so we can’t assess the degree of danger.”
It is also unclear how wide the flow of energy released by the burst of gamma rays will be. But, in any case, the cone of destruction emanating from the top will reach several hundred square light years before it approaches Earth, according to Melot's calculations. Tuthill states that “no one will be able to fly a spaceship far enough to avoid getting hit by the beam if it actually shoots in our direction.”
However, Tuthill believes that the spinning top may be quite safe for us.
“There are too many uncertainties,” he explains. “Radiation can pass through without causing us any harm if we are not exactly on axis, and no one is completely sure that death stars like WR 104, is able to cause such a powerful burst of gamma radiation.”
Future research should focus on whether WR 104 is actually aimed at Earth and on studying how a supernova birth results in gamma ray emissions.

Trilabites were once the masters of the Universe, the dominant form of life, but one day, 250 million years ago, they all went extinct. 90% of life forms were wiped out from the face of the Earth. The extinction is believed to have been caused by a burst of gamma radiation. Since this has happened before, is the Earth in danger of another hit of gamma rays?
1976, the height of the Cold War. The United States launches the Vela satellite to monitor the USSR for nuclear explosions. Suddenly their companion detects all sorts of outbreaks of hard healing. This raised a real panic in the Pentagon, whether the Russians were testing a new top-secret nuclear weapon in space. But scientists soon realize that they are faced with something much more deadly. They discovered gamma-ray emitting stars; they are the second most powerful in the Universe, second only to the Big Bang.
The source of gamma rays are giant stars whose mass exceeds our Sun by 50-100 times. Such stars are not called supernovae, but hypernovae, which at the last moment of their life splash out huge rays of hard radiation.
When a star goes supernova, heavy elements are formed in its core. But when a star with a mass of 50-100 solar masses dies, it does not turn into a supernova, its core continues to shrink (collapse) and turns into something strange. Into a black hole. The black hole quickly begins to consume the dying star, forming an accretion disk. But a black hole cannot absorb such a huge volume of star matter in such a short time, and it throws a significant part back in the form of a beam of pure energy directed from the poles. This is gamma radiation.
The phenomenon of gamma-ray bursts is the most powerful phenomenon in the Universe, second only to the Big Bang. Radiation energy only in the gamma range is 1.6×10^52 erg. This is a real brightness record holder. Gamma-ray bursts are observed at least once a day.
Believe it or not, one such star is pointing in our direction. We're looking down the barrel of a gun called the WR 104.
Yule, named WR 104, was discovered 11 years ago in the constellation Sagittarius. It circles "every eight months, with the precision of a space chronometer," says astronomer Peter Tuthill of the University of Sydney.
At the heart of this fiery cosmic spinning top are two stars revolving around each other. In such mutual rotation, flashes of flowing gas escape from the surface of the stars and collide in the intermediate space, gradually intertwining and twisting the orbits of the stars into rotating spirals.

Conclusion
This will definitely happen, the only question is “WHEN?”. Perhaps WR 104 is our death. But fortunately we won't be able to predict this in advance, the rays will hit us before we can do anything, so there's no point in worrying
Life on Earth may die from a beautiful cosmic spinning top - the death star. Unlike the Death Star from the movie “Star Wars,” which exploded when approaching a planet, this space object is capable of burning worlds thousands of light years away. The mysterious cosmic spinning top that threatens us is known under the name WR 104 and was discovered by scientists more than 8 years ago. It represents two stars in the constellation Sagittarius, which revolve around each other. In this rotation, the bursts of escaping gas from the two stars collide and form intricate spirals.
Both heavy stars that form WR 104 will someday explode as supernovae. However, already now one of them is unstable and is in the last form of life known to astronomers, before turning into a supernova. Astronomers call them ticking bombs that could explode at any moment.
What do scientists think about this?
According to Sydney University astronomer Peter Tuthill, the explosion of such a supernova will throw a powerful stream of gamma rays towards the Earth. The emission of gamma rays is the most powerful of all explosions known in the universe; in a short period of time up to 1 minute, it will be able to release as much energy as our Sun has released in all ten billion years of its life. The worst thing for us is that WR 104 is visible from Earth as a perfect spiral, which means that we are on its axis, along which the energy will be released during a supernova explosion.
Although the distance to this spiral is quite decent - about 8 thousand light years, the consequences of a supernova explosion can be disastrous for all life on Earth. Yule won't tear our planet apart like the Death Star from Star Wars, but even with a 10-second explosion, the gamma rays that reach Earth will destroy 25% of our ozone layer, which protects us from the harmful effects of ultraviolet rays. For example, over the entire period of its life, humanity has been able to reduce ozone layer by only 3-4%, creating the so-called ozone holes above the poles. The same part of the planet that is hit by the emission of gamma rays will experience consequences similar to the impact of a nearby nuclear explosion, which will provoke radiation sickness in living organisms.
But this is the most pessimistic possible scenario. In fact, there are many uncertainties, for example, we may not be exactly on the axis, and then the star’s radiation, which is deadly for living organisms, will simply pass away from us.
