🌟 What are the most common ways to discover an exoplanet?
The two most common ways are watching the planet travel in front of its star causing a small dip in the stellar light (the transit method), and the radial velocity approach.

🌟 Why is it important to study an exoplanet?
Studying exoplanets tells us not only a great deal about how planets form and how abundant they are but also the uniqueness of the Earth and our own solar system.
#astronomy
🌟 What are the different kinds of stars that we look for in order to find Earth-like or potentially habitable planets?
To detect smaller rocky planets like ours, we have focused on cooler and smaller stars that are close to our Solar System.

🌟 What is the habitable zone around a star that astronomers keep referring to?
The Goldilocks or habitable zone is the region around a star where a planet can support liquid water on the surface.

🌟 With the advancement of technology, would it be possible to get a direct, real view of such planets?
Even with these large facilities images will still appear as a point source, and we will not be able to take a direct picture of their surface features as these planets.
🌟 What are the chances of an exoplanet being habitable for human beings and other Earthly species?
With billions of stars in the galaxy, there are many exoplanets out there for us to explore, but it's unknown right now how unique we are,we only have one Earth to compare as yet
