Scientists discover a planet which has the most Earth-like condition ever.
The planet, called Kepler-22b is known to have a temperature of 72 degrees Fahrenheit (22 degrees Celsius) and is approximately 600 light years away from our planet which is located towards the constellations of Lyra and Cygnus. The planet is believed to have a radius of 2.4 times of Earth's radius. Kepler-22b's distance to the sun is believed to be 15% less than the distance from the Earth to the Sun, therefore orbits around it's sun every 290 days. As the Kepler-22b's sun is a G5 star, whilst our sun is a G2. As such, it has less luminosity than our sun.
So with the continous discovery of these stars, will the mankind eventually discover the signs of extraterrestrial lifeforms?
