Google celebrates NASA's Trappist-1 discovery with new Doodle

It is the first time such a number of exoplanets have been discovered and it leads scientists to the conclusion that the Milky Way may well be full of worlds that resemble planet Earth. Likewise, the planets all orbit the star at far shorter distances than we're used to here at home, though three of them still fall in this particular star's habitable zone, where conditions may allow for water and life.

Thomas Zurbuchen, the associate administrator of the agency's Science Mission Directorate in Washington, boasted, "This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life". Finding Earth-size, potentially habitable planets is believed to be the first step to finding other life in the universe.

NASA said all the TRAPPIST-1 planets are likely rocky, but further observations are needed to determine whether they have any liquid water on their surfaces.

"The energy output from sward stars like TRAPPIST-1 is much weaker than that of our Sun", said Amaury Triaud, of the Institute of Astronomy at the University of Cambridge. The enormous power of the telescope will enable astronomers to see into the atmospheres of the planets and look for evidence of oxygen, ozone and methane - considered possible signs of life - and will also calculate their temperatures.

As the name suggests, the game isn't just one game but two sizable hack-and-slash RPGs, so that's why it's so huge. Additionally, this variant edition comes with the alterable cover art of the Adventure Log.

The findings have been published in the Nature journal.

Three of the exoplanets were discovered moving around a star. The energy emitted by the star is sufficient to sustain the solar system as long as the planets have shorter orbits.

"I just don't want people going away from this thinking we have found Earth-like planets with life on them", he said.

The planets may also be "tidally locked" to their star, not rotating as Earth does and keeping each side in perpetual day or night, JPL officials said. Follow-up studies with ground telescopes and NASA's infrared Spitzer space telescope revealed at least four more sister words, all orbiting closer to their parent star than Mercury orbits the sun.
