Is earth unique ?

1. Milky way is the name of the earths galaxy

2. Eric Petigura is astronomer that found out that 1 out of 5 stars that they found that had the earth like planet that are in the Goldilocks 

3. Yes , Sara Seager which is another astronomer said that Erick's findings are credible .

4. In this article , it says that Erick had a computer program and he put fake planets in the same program to see if he could out smart the program , but the program rejected his fake planets. This is what made his findings believable. 

1. An Exoplanet is a planet that orbits around another star but not our earth . 
2. Most exoplanets are discovered by looking for wobbles in a star’s motion caused by the pull of a nearby planet.
3. I think that Exoplanets have a life because 1 out of 5 stars that they found that had the earth like planet that are in the Goldilocks.
4. . If intelligent life was found i think humans would find it by sending a signal out.
