Until now, the earth is the only planet that is real life. Plant diversity and animal diversity both are existing on this same planet. That is our earth. Through the topic, it is saying about another planet that is existing lives. That is great. Because other than the earth, there is a planet that is having conditions for existing lives. Now I know your question. That is how we can accept, is that correct. This is for you to understand the answer to your questions. Are there any lives?? We don’t know that actually is there any lives. We will see that through the following.
For me, it is very good news because we can form relationships with the other planets too. Then we will move to the main part of the article. Shall we??
Do you familiar with the Goldilocks zone?? Do you have heard about it? I think no. There is another name for that. It is a habitable zone. It is distance. Distance means the gap between a star and to the surface. Actually, that is not a normal surface. It is very special and different. What is that??? That surface should be a surface that contains liquid water. Finally, you know what is meant by the habitable zone.
That is the space between a star and land or surface that is containing water. And there should be another feature of that land. That is to be not so hot and not so cold. There are reasons for those things even. The water present in the land should not be vaporized or frozen. That is the hidden reason.
Then what is the reason to take consideration of the water? Because water is an essential ingredient for lives. You know in the food even though there are special ingredients that are present. Like that, water is the most needed ingredient. That can be depicted by some other words. We can say it if the water is not there, even lives cannot exist. But recent research proves something else.
We believe that plants also need water. Only water is not the ingredient that handles plants potential habitability. Then you know there are Goldilocks stars. As in the above, we will know some more about them.
There are many types of stars. They are categories under many sections according to their special features. From the above, you can understand that all the stars don’t seem the same. As for example, some of the stars are very hot and seem to be very brighter. Some are young stars while some of the others are old age stars. Plus, some stars maintain a low temperature inside. There is a specific name for these types of stars. Red M type dwarf is the name for such types of stars.
The above zone is nearest to the star. Then I thought to tell you more about the Goldilock stars. See that through the following. The following details will be more interesting than you think.
Sun is the main star we all know very well. Sun is included in the category of the yellow dwarf. Plus, a G type main-sequence star.
Other than our sun, there is another type of star that is suitable for lives. These types of stars can be declared as the best star for lives. That star type is the K type star. Those are orange-colored stars. It is cooler than the sun while warmer than the red dwarf. This above research is done by Villanova University.
There are other such types of stars. Those are known as K type dwarfs. This is a rare type of star. Those are more luminous than the others. Other than that, this is hotter than the other types of stars as well. You know there are more types of stars. Out of those many types, there are categories of stars from F to G type. Those types of stars are living with the sun in a time program for about 30 years. Plus, there is another type of red dwarf. It is the M type of red dwarf. Those types of red dwarfs are with the red dwarf program for about ten years.
After some time, the scientists expanded their research up to the K type stars. And they are called as Goldilocks K dwarfs. Even those stars seem to be life-supporting stars with the special features. Then we can make a comparison of the K type stars and the G type stars. I mean comparison of the habitable zone of both types.
The habitable zone of the G types of stars is much larger than the habitable zone of the K type stars. As you know, G type stars are some rare types of stars. That means K types stars are the most common star category. Even K types of stars have a much longer lifetime than the G type of stars. That is not the single word lifetime, but that is with the main sequence lifetime.
Our sun is now at the age of 4.6 billion years old. Plus, the sun has a main sequence lifetime of 10 billion years. Can you imagine how long this time is? We can think that much of the time because of our lifetime only valid for a few years, such as 70 – 80 years. According to scientists, someday we have to leave this planet. It happens when the sun begins to expand. The expanding sun will push the inhabitable zone of our solar system.
Then we will turn to the K type stars and the G type stars again. K types stars have a lifetime of 25-80 billion years. Even these above stars have a calm nature than the other stars. Have you heard these names??? See the following. Kepler-442, Tau Ceti and Epsilon Eridani. Those are some names of the planets that are near to the K types stars. Kepler 442 is a Goldilock planet. Its mass is two times as the mass of the earth.
There is an elliptical orbit around this planet. Inside the planet, there is a normal temperature maintained. Other than that, there may be a separate habitable zone for this planet. This research was released to the public at the 235th meeting of the American Astronomical Society in Hawaii.
Now we came closer to the end of this article today. I think I told you some wanted details for you. Even I told you some extraordinary details too. We will meet with another one very soon. Keep calm and wait for more time.
