TRAPPIST-1: The Discovery of Seven Earth-Like Exoplanets May Change Everything

NASA just went on a live-stream from Washington D.C. to make a very big announcement.

On Wednesday, February 22, 2017, at 1:00 PM. (EST), five NASA researchers / speakers went on a live-feed to make a very big announcement.

And it wasn’t about aliens.

Sorry!

However, they did reveal something extremely unique and interesting.

It’s a discovery that could not only prove possible alien-life, but maybe be a habitable star system for Earthlings …  someday.

NASA revealed the discovery of the TRAPPIST-1 Star System.

NASA researchers have found seven Earth-like exoplanets all around one star, TRAPPIST-1.

They were discovered using the Spitzer Space Telescope.

Most importantly, three of the seven exoplanets lie in the ‘habitable zone’ of the star system (think Venus, Earth and Mars around our Sun).

TRAPPIST-1 is not too far (relatively speaking). It’s around 40-light-years away (235 trillion miles) in the constellation, Aquarius.

“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of the Science Mission Directorate in Washington. “Answering the question ‘are we alone’ is a top science priority and finding so many planets like these for the first time in the habitable zone is a remarkable step forward toward that goal.”

Finding so many Earth-like exoplanets in a habitable zone, orbiting a single star suggests that similar astronomical occurrences (such as ours) may be more common than previously believed. It also offers a real tangible opportunity to physically study such an occurrence as opposed to just theorizing (as previously done).

According to a NASA Press Release, “All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth’s sky.”

Could these TRAPPIST-1 exoplanets share the same atmosphere?
