In the old days, many believe that humans are the only living things in the galaxy or even in the whole universe. No one even bothers to look beyond planet Earth and explore the space for that matter. Though in Ancient Egypt, Babylonians use to study the sun, moon and stars just to generate a calendar for farming and religious rites but it never extended that far.

Then, in early 1900's people started to explore space and study matters beyond our planet. Edwin Hubble was the first person who introduced us to the cosmos such as the galaxy and the universe. Hubble altered thinking of outer space and because of that, a space telescope was launched in Earth's orbit in recognition of him and called the Hubble Space Telescope.

Because of Hubble contribution on space exploration, astronomers and scientist are now conducting a future mission to explore and find an alien planet that might be similar to planet Earth according to Daily Mail. The space program is called "Project Blue" which task is to capture images of the Earth-like planet in space.

The report also says that the bold move from astronomers to take photos of these alien worlds will come from our nearest astral neighbors the Alpha Centauri system which is 4.37 light-years away from Earth.

The main focus of the project is to point the study on the two sun-like stars of the system - Alpha Centauri A and B - with a mission to target Proxima b, the world which many say have a similar characteristic of Earth.

The "Project Blue" initiative is a lightweight telescope which experts plans to launch into Earth's orbit in 2019 according to Space. The project could cost around $10 million to $50 million and project leaders are saying that the funds will come from community involvement, sponsorships, and other agreements.

With NASA's support, the project is set to dispatch a two high-altitude balloon test flights and a satellite with a refrigerator-size telescope which will orbit the Earth from 2019 to 2022 to collect data from Alpha Centauri system as per stated in the report.

Many also say that this is a risky mission but if it will become successful the next thing to do is to distinguish Proxima b, what it's made of and find out if it is habitable for other living organisms.
