NASA´s Kepler discovers more than 104 new exoplanets

WASHINGTON: A global group of scientists reported Monday the disclosure of 104 new planets outside our close planetary system, including four that could have Earth-like, rough surfaces.

Researchers found the exoplanets utilizing the Kepler space telescope and in addition ground perceptions by Earth-based telescopes, including four on the summit of Mauna Kea in Hawaii.

The $600 million Kepler mission has permitted researchers to find more than 4,600 planets – 2,326 of them affirmed – since it dispatched in 2009.

“The differing qualities of planets is dumbfounding,” said Evan Sinukoff, a space expert at the University of Hawaii who added to the examination.

“We found numerous planets about double the measure of the Earth circling so near their host stars that they are more sultry than 1000 degrees.”

The most recent trove incorporates 21 arranged inside their sun’s livable zone – the separation from a star that could allow fluid water to exist and bolster life.

The four conceivably rough planets – extending from 20 to 50 percent bigger than Earth – circle firmly around the same star in a planetary framework around 400 light-years from Earth.

Despite the fact that the planets turn around their star significantly nearer than Mercury circles the sun, two of the planets may have surface temperatures like Earth’s, as their star is cooler than our sun, space experts said.

The unmanned Kepler mission has been checking 150,000 stars in the Cygnus group of stars for indications of circling bodies, especially those that may have the capacity to bolster life.

It works by watching a darkening in the light of a star, known as a travel, every time a circling planet goes before it.

In 2013, the space telescope endured an issue with the response wheels that normally keep the shuttle unfaltering.

NASA in this way set the shuttle on another mission called K2, to study supernovas, star bunches and far away universes.

Researchers checked the most recent exoplanets as a component of the K2 mission.
