Hello friends, let's talk about those amazing "super-Earths" now! I'm sure you've all heard that scientists are constantly discovering new exoplanets in outer space, and one of them is called "super-Earths," which are very similar in size and conditions to Earth. Today, I would like to introduce you to a particularly eye-catching "super-Earth" - "Kepler-452b".
First, let's take a look at some basic information about the planet. Imagine a planet orbiting 1,800 light-years away from Earth in the direction of the constellation Cygnus. Well, doesn't that sound mysterious? It's called Kepler-452b because it orbits a star that is very similar to the Sun, Kepler-452. This star is only 3.7% larger than the Sun and has a radius of only 1.11 times that of the Sun.
However, what attracts the most attention of scientists is that the conditions of this "Kepler-452b" are so similar to those of the Earth. Can you imagine a planet that is 5 times the mass and 1.5 times the radius of the Earth, but has the same environment as the Earth? It's like a "super version" of the Earth! The most important thing is that Kepler-452b is located in the habitable zone, which means that liquid water can exist there, which is absolutely necessary for the development of life.
If you look at the orbit of Kepler-452b, how many days do you guess it? Wow, it's 385 Earth days! Not only that, but it is not yet "tidal locked", which means that there will also be an alternation of day and night on that planet, just like on Earth. Can you imagine a "super-Earth" that has been orbiting in the infinite universe for 6 billion years, and like we do now, experiencing sunrise and sunset every day!
Of course, Kepler-452B also has something that is not quite the same as the Earth. For example, its surface gravity can be twice that of the Earth. Imagine what it would be like if we lived in that environment? Will the body be deformed by gravity? Will it affect the evolution of living things, making them short and flat? Haha, maybe then, the image of aliens will really appear!
However, the most attractive thing about Kepler-452b is that it has been in the habitable zone for 6 billion years! The age of the Earth is only 4.55 billion years, which shows that Kepler-452b is nearly 1.5 billion years older than the Earth. Scientists speculate that life appeared on Earth at least 3.77 billion years ago, but what about Kepler-452b? Could it have given birth to life and even developed an intelligent civilization earlier than Earth?
If Kepler-452b really has a more advanced civilization than humans, what should we do? Have you ever thought that in the face of advanced civilizations, we humans may not even be as good as ants? It's as easy as looking at ants and trying to get rid of them. So, if those advanced civilizations are willing, maybe they only need to wave their hands, and we humans will be wiped out, are you afraid?
Of course, this is just my whimsy. So far, we have not found any evidence of the existence of extraterrestrial intelligent civilizations. But then again, if there really is an advanced civilization and they discover humanity, what should we do? Do you think we should take the initiative to get in touch with them, or, as Hawking said, keep silent to the outside world so as not to get into trouble?
Hehe, it seems that the topic we are talking about today is really a bit mysterious. But don't worry, we shouldn't be able to be invaded by aliens anytime soon, because even human immigration to a planet like Kepler-452b is still a distant plan. Therefore, we should be more concerned about the current life, cherish all the resources and environment provided by the earth to us, and take care of the home we rely on for survival.
In conclusion, Kepler-452b is undoubtedly a miracle in the universe, which gives us another slim hope that life may possibly appear. But instead of blindly fantasizing about the unknown, it's better to calm down and think about how to protect what you have. After all, the earth is our true home and the foundation of life. Let's work together to take care of this blue home!
