Question: is there much chance in finding a new planet that can be inhabited by humans???

Absolutely! We have already discovered over 550 planets in our galaxy and that number goes up practically every week, it’s mental!
All those planets are different, different sizes and different atmospheres. Once our new telescopes come online (next couple of years) we will definitely find planets that can be inhabited by humans.. I’m willing to put my money on it! 🙂
One telescope to look out for is called the James Webb Telescope. It is a space telescope like Hubble. It will be so powerful we will be able to study the atmospheres of other planets and say ‘yep! we could live there!’ 🙂
