This is a mysterious object from 7500 light-years away, it is known as the largest, heaviest, brightest star in the Milky Way, it is not a star, but a star system. But for the earth may be a stealth bomb star system, what is its origin, what impact will it have on the earth? In this issue, I will take you to find out.
This is the Carina Nebula on the Centaurus arm of the Milky Way, about 7600 light-years away, which can also be called the Carina Nebula. It is a red emission nebula that contains countless stars and spans three hundred light-years in the universe. It is one of the few large nebulae in the Milky Way, and when it comes to the Carina Nebula, one celestial body that cannot be mentioned is Seamount II. When we first discovered it, it was even brighter than a second star other than the sun, becoming the most conspicuous dot in the sky. According to current data, the massive star is a binary star system, an extremely unstable star compared to our Sun.
First, his mass is hundreds of times that of the sun, like nuclear fusion that occurs every moment inside the sun, which in the eyes of Seamount II is like a pediatric child. Not only that, it's about five million times brighter than the Sun, and yes, it's a binary system. Because of the planet's terrifying exterior, we can't even tell what kind of star it is. This binary consists of a primary star with two hundred solar masses and another substar with 80 solar masses. Along with its high temperature, a large amount of ultraviolet rays are constantly radiated.
During the long period of observation, our scientists once judged the seamount as a death star. The reason is that it is quite unstable and often has large explosions, each of which spills more material into space. During an outbreak, his shape also changes like a dumbbell. According to statistics, the most recent explosion of Seamount II was probably in the early to late eighteenth century, and by that time his light had reached its peak, and even our naked eyes could directly observe it. Seamount II This supernova-level explosion.
With the launch of the Hubble Space Telescope, we were able to observe this amazing picture of the universe again, where the ejected material formed two huge petal-like structures at its poles, with a current maximum radius of about 3.3 trillion kilometers, or about 1/2 light-year. Based on the size comparison of the images taken in recent years, scientists can speculate that its outermost expansion rate has reached an astonishing 670 kilometers per second! The part linked between them is called the equatorial skirt, which wraps the core of the entire star cluster and constantly generates gamma-ray bursts from its core, which is an extremely dangerous star cluster.
After that, the star's light gradually weakened. It lasted until the 19th century, when we looked at it again, we couldn't see it intuitively. Even so, as the brightest seamount in the Milky Way, its radiation pressure is still strong enough to counteract gravity. And over time, it will one day lead to supernova phenomena.
For stars, we may also know that their own lifespan is closely related to their mass, and it is currently in the late stages of the star. Astronomers believe that Seamount II will eventually end its life cycle in the form of a large explosion over the next few hundred thousand years. As mentioned earlier, it has huge energy and is also a twin subsystem. That is to say, there are a large number of other celestial bodies in the galaxy where it is located, and the mass of Seamount II is a hundred times that of Earth.
Seamount II is only 7500 light-years from Earth, so it could affect Earth in the event of a supernova explosion or an extremely supernova explosion, but it is unlikely to directly affect humans because the atmosphere blocks foreign gamma rays. The impact of the impact is likely to be limited to the upper part of the atmosphere, which includes the ozone layer, spacecraft, satellites and astronauts in space.
Although it will not attack the interior of the Earth, it is a star that can explode at any time, not only a stealth bomb for the Earth, but perhaps a potential threat to the entire solar system. The evolutionary path and age of Seamount II have not yet been determined, so the explosion may occur millions of years later, it may occur tens of thousands of years later, or the light of the explosion may already be on the way.
