According to researchers, the Earth is now around 4 billion years old. That is quite a number for an age. The Earth has changed a lot since then; from its structure geographically to its components atmospherically.
The sad news is, instead of helping the planet to preserve its life, the people living on it is hastening its degradation. Also, the earth is not immortal, and it will soon reach its limits. Though it will be hundreds of years more but still, the race of humankind is at stake.
For this reason, researchers from NASA are doing studies beyond the universe to look for any candidate of a new planet where we could live. For years, they have tirelessly navigated the vastness of the cosmos just to look for similar (if not entirely identical) a habitual planet like Earth.
Habitable Exoplanets Catalog (HEC) has come up with a list of planets that are considered to be habitable. The following exoplanets are information taken from HEC and the NASA’s Exoplanet Archive.
There are more exoplanets that astronomers had discovered. The following have been listed too such as TRAPPIST-1e, Gliese 832 c, HD 40307 g, and many more. These exoplanets in the habitable zone suggest that a neighboring planet within the habitable zone should have the conditions that are roughly comparable to those of Earth.
Upon discovering the numerous planets that are considered habitable, what then is the next step that these researchers would do? Because the level they will be making means that it can become the step of the human race. Are we ready to travel through space just to find a new home or should we preserve what we have now?
