Mysterious outer planet, 600 light years away! Will it be our second Earth?

In science, there are many asteroids in the universe. In recent years, in the exploration of space, it is indeed difficult to discover the existence of other planets in addition to the known planets.

Recently, international astronomers accidentally discovered a mysterious "baby" outer planet, located 600 light-years away, and scientists are still expanding, which is a Ttauri star. According to preliminary conclusions, this "baby" outer planet is only about 2 to 3 million years old, and is also surrounded by primitive dust and gas, will this become our "second" Earth?

The researchers' initial view is that the current positioning of the planet is different, because we have observed a different orbit around it, and only two binary companions orbiting it are currently visible, which may be a brown dwarf or a super-Jupiter.

Scientific observations of these exoplanets are scarce because their existence is difficult to detect, and it is now thought that they may be located in the baseline system of planets and brown dwarfs. In the past, science has announced that planets located hundreds of light-years away may be suitable for human habitation, but this time the discovery is relatively closer.

In science, human beings continue to search for a new earth, including the discovery of new planetary operating systems, in order to see the existence of an operating system based on the earth model, and to see if there is a planet suitable for human habitation. In the past few years, it has ended in failure.

In terms of the entire universe, there will definitely be planets similar to the earth, but the distance between human discoveries is also very small, we don't know whether the universe has boundaries or not, there is scientific proof that the universe is expanding, the sun is expanding, and now the "baby" outer planets are also expanding, and no one says that our earth is expanding. Will there be a "second" Earth in space?

This mysterious outer planet is 600 light-years away, and it has actually been confirmed that there is life on it, and there are resources on it, which is suitable for human habitation, and may be our second Earth.

I don't think so, some researchers are still in the early stages of studying this planet, and they don't know much about what is going on around it. It's still unrealistic to define it as a second Earth.

The mysterious outer planet, 600 light-years away, is likely to be our "second" Earth, because this planet is still surrounded by primitive dust and gas.

The mysterious outer planet is 600 light-years away, this outer planet has not been deeply understood and explored by humans, but only analyzed on the surface of the appearance, it may be very similar to the Earth, and with the continuous evolution of the times, it may become a second Earth.

Now, with the help of astronomy, we know that there are eight planets in the solar system, and these eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, which rotate around the Sun from the moment they are born.

In fact, in the early days, scientists did not know that planets were universal in the universe, and due to the limitations of observation technology at that time, they only speculated that there might be planets outside the solar system. It was not until the early 90s of the 20th century that the conjecture of exoplanets was confirmed.

In 1995, Swiss astronomers discovered the first exoplanet for the first time, which is about 50 light-years away from Earth, in the constellation Pegasus, and is a hot Jupiter.

Since 2002, dozens of exoplanets have been discovered every year, and so far more than 4,800 planets have been discovered in nearly 3,500 star systems, including gaseous planets and habitable planets similar to the Earth.

For example, we are familiar with Kepler 452b and Kepler 22b and so on. The discovery of these planets has also further deepened our understanding of the universe.

However, although these discovered planets are exoplanets, we have to accept the fact that they are still within our galaxy, and the farthest is only a few thousand light-years away. Since the Milky Way is 160,000 light-years in diameter and contains nearly 400 billion stars, and extragalactic galaxies are very far away, it is extremely difficult to find planets beyond the Milky Way.

But recently, according to the latest issue of the journal "Nature Astronomy", there has been a major discovery, astronomers from Harvard University may have discovered the first extragalactic planet, which is located in the M51 galaxy 28 million light-years away from the Earth.

The M51 galaxy is a collision galaxy, which is actually composed of two galaxies, the larger one is called M51a, and the companion galaxy next to it is called M51b, and this planet is located in the large galaxy M51a.

At that time, astronomers detected a bright radio source on a cantilever of M51a through the Chandra radio line, using the principle of transit, and the data showed that it was a binary star system, in which a massive star was moving around a compact star, and was constantly accretted by the compact star, producing a large number of X-rays, this compact star may be a neutron star or a black hole.

When astronomers observed this radio source, they found that the brightness of this radio source decreased rapidly for a period of time, and then recovered, so scientists speculated that it may be a planet moving around this dense star, causing its brightness to flicker and darker, because under normal circumstances, only when the planet passes, there will be a similar transit phenomenon.

However, due to the small amount of data available, it is only speculated that it is very likely to be a planet, and it is not yet 100% certain, and it is believed that after a long period of observation, the answer will finally be revealed, and then it will also be a major discovery in the history of astronomy!
