Living Conditions in the Goldilocks Zone

Ever since we, the only thinking and pondering intelligent beings living on earth, i.e. human beings, started looking at the universe apart from our own earth and gained awareness and information about it, then it was possible to see it around us, in the neighboring planets. Saddened, surprised and sorry that no life was foundThe large solar system, in which the family Sun, eight giant planets, five dwarf planets and their nearly 290 moons are roaming in the vastness of space, has not found any signs of life anywhere. Then, through his space knowledge, human beings also learned that our sun is not the only star in this Milky Way galaxy where planets are found, but this galaxy is estimated to contain 100 to 400 billion stars, around which not many The planets will be rotating like our solar system. Likewise, there are 2 trillion galaxies in the entire universe with far more stars than the number I just estimated above for just the Milky Way. How many planets will there be in them that will be orbiting around these stars, just your thinking is enough for that. 

Well, let's take it a little further. When humans realized that where we live, our only home i.e. the planet earth, billions of trillions of planets like it can be found in this universe, where conditions and climates exactly like Earth can be found, then Hazrat Mansana The disappointment that was felt after seeing the conditions of the solar system, started to diminish little by littleAnd a glimmer of hope was awakened that we might not be alone in this universe. Life like us (not exactly like our terrestrial life) might be found somewhere else on another planet. 

But on which planet? This is one possible question that may immediately come to a person's mind. 

So the answer given by space scientists is that according to the model of life on Earth, a planet that would be in the Goldilocks zone of its host star, there might be a possibility of finding life, as in the past with our Earth. has happenedThe distance the Earth orbits the Sun is just right for water to be in liquid form. Similarly, the distance our earth is from the sun is neither too much nor too little, otherwise the earth will become very cold if the distance is too much and if the distance is too little, the earth will be extremely hot, and in both cases there will be no possible life. The chances of initiation, maturation and development are reduced. This ideal distance from the Sun is called the habitable zone or Goldilocks zone. Rocky planets in the habitable zones of their stars are the most likely targets for detecting liquid water on their surfaces, which could also lead to the discovery of alien life. 

In order for life to start on any possible Earth-like planet, it must not only be in the habitable zone, also known as the Goldie-Lock Zone, but also some other factors. Essential, like being carbon-based, having plenty of water, proper digestionThe planet must have an atmosphere and the planet must be rocky. Many of these conditions are of course based on terrestrial biological samples, but what to do, we do not have a model of life anywhere other than Earth at the moment, so these conditions are written based on terrestrial life. 

1. This planet must be massive. In which its heart is made of a large part of iron or nickel. This rule rules out planets with masses less than 0.7 Earth masses. The smaller the planet, the smaller its heart or core will be. The small core of any such planet would cool very quickly. It would then disable the electromagnetic field and thereby destroy the planet's water cycle, the hydrosphere, the outer atmosphere and by extension the biosphere if any were possibly found there. 

2. This planet should have large amount of water. Some scientists here, but many others, also recommend liquids. But in reality, water is the most abundant molecule in the universe, and it is probably the most readily available molecule in the universe. It has the best properties of all the liquids we find, mineral solubility, large temperature range of the liquid state, density, etc. And liquids rarely have these properties. 

3. It seems that any life in the Goldilocks zone would require a planet to have a large moon - it stabilizes the rotation axis, causes tidal action, keeps the electromagnetic field generated. Is. 

4. This potential planet must orbit its host star at a distance where it can receive about 1.2-0.7 the energy from the star that Earth currently receives. 

5. It probably shouldn't be tidally locked, meaning it shouldn't be orbiting the star sideways like our moon or any other planet, but the planet should also rotate on its axis for a period of time. It must also rotate axially, which completes a specific day/night cycle. Due to the balance of day and night, a suitable temperature difference is created on the planet that can support life. 

6. The host star must not be a Red Dwarf (all the red dwarfs we have seen later erupt with intense fire and energy that would wipe out not only any life, but also the atmosphere and hydrosphere from that potential planet. do)

7. It must be a terrestrial (rocky) planet. H, C, O, N, P, Fe, Zn, Mg, Ca, Na, K, S, Cl and other elements are required inside a planet for the existence of any life. But we take all this information in terms of earthly life. Here we don't see gas giant planets as potentially life-bearing planets, but the giant moons of these planets might be a possibility for life.
