Say Hi to Earth 2.0 – NASA’s Kepler telescope finds another planet similar to Earth

It has always been speculated that there must be a planet similar to our Earth somewhere in the space and which can sustain life on its surface. Such a discovery would give answers to many questions that our scientists have been having for all those years.

But a few days ago, NASA’s Kepler telescope found something that might be the discovery of the decade. It found a planet in the Cygnus constellation, which the NASA has named Kepler 452b which has similar features to our Earth and is considered to be Earth’s twin or Earth 2.0. Kepler-452 is 6 billion years old, 1.5 billion years older than our sun, has the same temperature, and is 20 per cent brighter and has a diameter 10 per cent larger.

Humans and scientists from various organisations form around the world have been always looking for another Earth in our solar system or universe. They have always believed that there are multiples planets with features similar to Earth that can support life on its surface.

2 Kepler telescope and Cygnus constellation

The Kepler spacecraft was launched by NASA in 2009, with the objective to survey a portion of our milky way to discover Earth like extrasolar planets, near the habitable zone and find out the number of such planets there are in billions of stars of our galaxy.

Recently as of January 2015, the Kepler has reported 1,013 confirmed exoplanets in 440 stellar systems. In May 2015, it observed and reported a newly discovered supernova KSN2011b during and after explosion.

3 Discovery of Kepler 452b

In July 2015, NASA confirmed the discovery of a confirmed exoplanet orbiting the habitable zone of a Sun like star. It was named Kepler 452b and is the sixth most Earth like exoplanet known to date. The planet and its star is about 1,400 light years away from our Earth and it will take approx. 25.8 million years to get there.

4 Kepler 452b and its features

The planet orbits its star at the same distance as Earth does and even its star is very similar to our Sun. on being asked if it could sustain life, NASA said that if we transferred plant to the planet, they would most likely survive.

Kepler 452b is 1.5 billion years older to our Earth; hence it gives a rare glimpse into the future of our planet. The planet is 60 per cent bigger than Earth, and is located about 1,400 light years away in the constellation Cygnus. Despite being larger than Earth, it has only a 385 day orbit and it resides in the Goldilocks zone- which is an area around a star where water can pool on the surface of the planet in liquid form.

“This is so fascinating because Kepler 452b receives the same kind of spectrum and intensity of light as we do on Earth, this means plants from our planet could grow there if it were rocky and had an atmosphere. “said Dr Daniel Brown, an astronomy expert at Nottingham Trent University.
