The space telescope Trappist (in Peru) discovered a new solar system in our galaxy.
Seven new planets, all close in size to Earth, and maybe warm enough for water and life has been discovered around a small star in the constellation of Acquarius .
The discovery has excited astronomers that hope to find alien life in a different solar system not too far from ours.
It is the first time that so many Earth-sized planets have been found in orbit around the same star.
Compared to the Earth their sizes are ranging from 25% smaller to 10% bigger.
The planets closely circle at ultra cool dwarf star. Star’s name is ‘’TRAPPIST-1’’ which is at 39 light years away and is the prime candidate to search for life. The star is a little larger than Jupiter and fainter than our Sun.
If these planets were in the our solar system they wouldn’t have liquid water because the planets are so close that the water will evaporate, but the star is so cold that is possible the presence of liquid water.
If hypothetically we went on the fifth planet of TRAPPIST-1’s sistem (considered the most livable) we would see a star 10 times bigger than our Sun because it is very close to its own star. The planets are on such tight orbits that it takes between 1.5 and 20 days for them to whip around the star.
Some of the planets are thought to be the right temperature to host oceans of water and atmosphere.
The Hubble telescope could detect methane and water in the alien air, but both can be produced without life.
Whoever believes in aliens in few years could be avenged!
