NASA discovered three new Earth-sized planets and they are all in habitable zone!

NASA discovered three new Earth-sized planets and they are all in habitable zone!

Before the big reveal, lots of speculations are going around regarding NASA’s exciting discovery. Some people say that they will finally announce of the existence of extraterrestrials.

Some even says that they will launch a project like what we saw on movies (like Passengers and Interstellar) where people will be sent out to new planets to build new life.

None of these are correct as NASA announced that their telescope discovered seven new planets around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1.


What’s more exciting and amazing about their discovery is that three of the seven earth-sized planets are firmly in the habitable zone.

NASA & TRAPPIST-1- A Treasure Trove of Planets Found

We're celebrating a new discovery! A treasure trove of new planets were found around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of the seven planets are firmly in the habitable zone. Details: http://go.nasa.gov/2lvVN7G

NASA’s Spitzer Space Telescope newest discovery sets a new record for greatest number of habitable planets found around a single star, outside our solar system.  

All of the newly discovered planets have liquid water which is a big sign of life.

They all have the right atmospheric conditions but chances of human life are bigger with the three habitable zone.

According to Thomas Zurbuchen, associate administrator of the agency’s Science Mission Directorate in Washington, this discovery is a significant piece in the puzzle of finding new habitable earth-like planets.

This is also a big step forward toward the goal of answering the question ‘Are We Alone?’, which becomes a top science priority for the agency.

The new planets are about 40 light-years away (235 trillion miles) from Earth. It’s relatively close to us and NASA classified them as exoplanet as they are located outside our solar system.

This exoplanet system is called TRAPPIST-1, named for The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile.

Back in May 2016, researchers using TRAPPIST discovered three new planets in the system.

And with the assistance of several ground based telescopes, the existence of these planets are confirmed and discovered 4 additional ones thus the existence of TRAPPIST-1 system with seven planets.

These discoveries were published publicly on February 22, 2017 and were officially announced at a news briefing at NASA headquarters in Washington.
