Recently, astronomers discovered a solar system much like ours that could potentially support life. Seven earth-sized planets orbiting nearby star Trappist-1 were found this past week. The solar system is 40 light years away from the Earth. At least three of the seven planets are the right temperature to sustain life. They're rocky and could have oceans. Their orbital periods range from 1 to nearly 13 Earth days. All of the planets are located within a distance from Trappist-1 that is 1/5 the distance from Mercury to our sun. However, Trappist-1 is a relatively cool star, making the temperatures on these 7 planets not too hot despite their close proximity to their sun. This discovery indicates an increased possibility of extraterrestrial life, which is pretty cool. We are still millions of years away from ever being able to travel to this planet, but nevertheless its discovery is exciting.
