Has the United States really discovered a second Earth ?

On December 5, 2011, NASA announced that the Kepler Space Telescope project had confirmed the first Earth-like, habitable planet outside the solar system. The planet is located about 600 light-years away from Earth and is twice the size of Earth. It orbits a sun-like star every 290 days like the Earth orbits the sun.

Scientists say the planet's surface temperature is about 70 degrees Fahrenheit (equivalent to 21 degrees Celsius), and there may also be liquid water on the planet, which is very habitable.

Happy? Finally found our twin brother on Earth. Wait!

First of all, I want to tell you that even if this planet is exactly the same as our earth and suitable for human habitation, according to the current science and technology of our human beings, it will take 9 million years to travel from the earth to this planet in the fastest spacecraft! Think about what kind of concept this is?!

And of course, don't be discouraged! If you think about the history of mankind, there are only a few thousand years of written records, and our earth is 4.6 billion years old, and scientists speculate that our earth is only in the prime of life now, and there are still four or five billion years of life!

The rapid development of science and society has far exceeded your imagination! Anything is possible! According to the current development of mankind, anything can happen in the years to come!

This news, for us now, may be an after-dinner conversation, not happy or not, but for us human beings, it is not a blessing.

After all, this is the continuation of life!

The United States discovered the "second Earth", and the distance from it is unimaginable, and it is suspected that there are living creatures living there.

In outer space, 120 trillion miles away from Earth, a planet has been discovered that could be suitable for human habitation. It's about the size of Earth, it may have liquid water, it has the right temperature, and if humanity is forced to leave the country one day, it will be our new hope.

The planet has Earth-like temperatures, is about the same size as Earth, and possibly has liquid water, and is about 120 trillion miles away.

According to the United States**, the planet orbits around a planet called the "Red Gnome". The "red gnome" is much smaller than the sun, and does not have the strong burning heat of the sun. Plus, there's a lot astronomers don't know about this new planet.

It is worth noting that the basic definition of a habitable planet by scientists is that it is about the size of the Earth, has a temperature similar to that of the Earth, and has liquid water. As far as the solar system is concerned, Mars is still close to the definition of habitability by scientists.

The announcement released by astronomers on April 24 included planets outside the solar system in the category of habitable planets for the first time.

The new suspected habitable planet was reportedly discovered by an astronomical observation team of 11 European scientists. Michael, an astronomer at the University of Geneva, a member of the group, said: "This is an important step in our search for extraterrestrial life in the universe.

This is a welcome finding, but we still have many problems to solve. ”

The planet is named "581c" and weighs about 5 times as much as Earth. Astronomers who discovered it are currently unable to determine whether 581c is a rocky planet like Earth or an ice ball with liquid water on its surface. If it had a rocky structure like the Earth, it would be twice the diameter of the Earth, or even larger if it was just an ice hockey.

Theoretically, Michael said, "581c" should have an atmospheric environment, but what its atmosphere is made of is still a mystery. If its atmosphere is too thick, then its surface temperature will be ridiculously high.

This message was the first one I posted, hehe.

Plausibly true.

It's as if NASN says it's light-years from Earth.

Grace 581c is the third planet orbiting the star Grims 581. The mass is 8 times greater than that of the Earth, and the gravity is twice that of the Earth (if you weigh 70 kilograms, it becomes 100 kilograms on that planet). This allows the planet to orbit the parent star at just the right distance, at a moderate temperature, and with liquid water.

And its own size is also within the tolerable range (times the earth's gravity is still within the range that humans can bear, which is equivalent to carrying a big travel bag all the time).

But this planet is not necessarily suitable for life, first of all, the conditions for life to survive are not limited to liquid water, this is only one of the necessary conditions. The planet may not have the oxygen to breathe life, and the ozone layer may not have the ultraviolet rays to protect the stars. Secondly, since Gris 581 is a smaller star than the Sun, Grace 581c can get a warm enough climate precisely because of its proximity to it.

But this raises another problem, which is that the planet does not rotate. Because it is so close to the star, the star's huge gravitational pull dissipates the kinetic energy of the planet's rotation. Whether life on Earth can survive on a planet without a day-night cycle is really unknown to us.

Finally – this planet is 20 light-years away from Earth, and the biggest question is how we get there. According to the current human speed, the fastest probe is only 30 kilometers per second, and it will take more than 10,000 years to fly out of the solar system and 200,000 years to fly to that planet. It is impossible for a spaceship to travel to this unknown planet with 200,000 years of supplies, and it is still unknown whether this planet will be able to provide for the survival of life, only when it arrives there.

If it is judged that it is not possible, it means that all human beings who travel there will be buried in the universe.

Space travel is not as chic as StarCraft, you can travel freely between multiple planets, and it is completely impossible with the current level of human technology.

A second Earth was discovered? The temperature of 21 degrees Celsius is suitable for human habitation, and we are only 600 light-years away.

To date, astronomers have discovered about 220 planets outside the solar system, seven of which are structurally similar to human Earths. Of these 7 terrestrial planets, 2 are very cold, and the remaining 4 are too close to their stars for little chance of life.

In July 1998, an international team of astronomers from New Zealand and Japan discovered the first planet resembling Earth. The planet is 10,000 light-years away from the Earth, near the middle of the Milky Way, its diameter is similar to the Earth but slightly larger than the Earth, and the mass may be between the Earth and Neptune, that is, slightly heavier than the Earth, orbiting around a **celestial body with the same heat as the Sun.

No, there is no planet like Earth that is suitable for human life.

Don't blink. Scientists have discovered a second Earth. In the vastness of the Milky Way.

Even the natural environment and temperature and climate are the same as those of the earth. And the planet has mountains, mountains, water, and land.

And. There is actually a green cover on it. Its mass and size will be greater than that of the Earth.

This planet can definitely be called the first choice for human planets to migrate in the future. Needless to say, it can be called a second planet. It's a very strange thing to be in such an excellent environment.

on the planet. However, no organisms or species with life characteristics were found. It can be understood as.

It is possible that the Earth has been treated. But something that gives scientists a headache. Dry planets are highly likely.
