Using computer simulations, researchers were able to estimate that more than a third of the planets in solar systems containing giant planets are Earth-like - and some of them may even have conditions suitable for the existence of life
In the nineties, planets outside our solar system were discovered, a discovery that raised the hope of finding life in space light years away from us. To date, more than two hundred such planets have been discovered (210, as of the time of writing these lines) and more are on the way. These discoveries, as exciting and fascinating as they are, still do not foretell the possibility of the existence of life outside our solar system, in any case - organic life as we know it. In order for a planet to be able to support life on it, it has to meet several conditions, one of which is that it is an Earth-like planet: a planet similar to the Earth in several characteristics, including size, the existence of water on its surface.
The fact that no Earth-like planets have been discovered yet does not mean that they do not exist; Perfecting the means of observation in the coming years may lead to the discovery of such planets. Recently, scientists at NASA claim that not only do such planets exist, but that they are very numerous. According to their estimate, more than a third of the planets in solar systems containing giant planets are Earth-like. This estimate stems from calculations that were conducted, in which the influence of "hot Jupiter-like planets" was taken into account. These are planets that are very close to their parent star (their sun). Although they were formed in places further away from their parent star than where they are now, they migrated towards their parent star as early as the formation of the solar system of which they are a part. In doing so they caused, due to their gravity, changes in the space around them, and stimulated the creation of Earth-like planets.
The movement of these planets resulted in the ejection of much material from the protoplanetary disk (the disk of material from which the solar system is made before it crystallized into planets and other bodies) outwards. The planetary material has been thrown into an orbit where it is more likely to collapse in on itself and form Earth-like planets. At the same time, the friction with the material surrounding the parent star (the proto-planetary disk) slowed down the speed of bodies made of ice, located far from the Earth-like planets. Due to the slowing of their speed, they moved towards the Sun, and in the process transferred water to the nascent planets, which resulted in the formation of oceans on their surfaces.
The scientists, who used computer simulations, suggested that one out of every three solar systems that have developed contains Earth-like planets located in the habitable zones around the mother star. According to the scientists' estimation, the time for the formation of an Earth-like planet in the habitable zone reaches a maximum of 200 million years. Will it turn out in the future that our galaxy is indeed full of Earth-like planets and maybe even teeming with life?

You're brilliant, but there are mistakes, nobody's perfect, we don't go round and round. We have already started sending frequencies to the space creatures in which it is explained that we live on the third planet from the sun about our reception method the radio telescope about the double helix of DNA There are NASA programs for programming software with the help of the home computer it uses the processor power that is not being used and there are already 5 million People who use it and it has contributed more than 2 million years of computer time! Have you heard of the Razvel affair? What do you think ? Are you a believer or a skeptic?
True and stable, the joke is on us
The universe is teeming with life, it is only us who are separated from the rest of life. We are simply not on the frequency of the universal "life".
And all day long we look for life in our frequencies, the ones that are separated, that's why we don't find life. But "our eyes" improve, and as a result, our imagination also expands a little.
And the previous commenter really said, why are our mothers only looking for a culture like ours? It's not narcissism, it's apparently intuitive, and also allows communication. If they speak Hebrew or English it's easier...
But this is not true in another respect, our culture carries our limitations. And these are severe limitations... for example looking at and measuring at the speed of light, and movement is limited in range and speed which is not relevant even to the close spaces of our galaxy.
And I suggested - not to be afraid to search in the last directions, to agree to leave the limitations of our knowledge bases and search also in the unknown. Get rid of the "knowing ego" and agree to leave for the rest..
After all, it is known/apparently turns out that most of the universe is dark matter. A substance whose essence we do not know at all! It is known that man uses only 5% of his brain. It is known that only 5% of DNA is "valuable" and the rest is called "junk DNA". Well then, don't we understand that the joke is on us! And we go round and round in our mud puddle….
But it's not bad, everything is changing very quickly, it's no longer possible to ignore the looks... Why in a brain that is not small, why in such wonderful mechanisms of evolution do we carry so much junk DNA ??? Because it is not junk and the brain is unnecessary... Evolution knows this very well
Lucky that we don't have to decide for evolution how it should work, because if then... nothing would work.
Happy and interesting year

First of all, I must point out that when we talk about finding an Earth-like planet and in addition - liquid water on its surface, we talk about the hope of finding life as we humans know it...only.
It is not right to turn our gaze and love only to the likes of the land. And why should we ignore creatures who are more intellectually developed than us who can teach us a lot? But alas - these live on a giant where the average temperature is 70 degrees Celsius, they drink ammonia and in general - the main means of communication (which was developed by us) is sign language which they perform with the help of their eight front upper arms! What will we do with them? They live on such an unfriendly planet... and I say then what? Do you agree with me that we should not contact them? Of course we will. So why ignore the possibility that such life also exists?
The aspiration to first of all find a life similar to us expresses the narcissism that we all have and it is our nature. And yes, I say this despite the benefits of finding a life similar to ours on Earth.
