In April 2017, only months before the end of Cassini's mission at Saturn, two discoveries from Enceladus's plumes suggested that its subsurface ocean is in contact with bedrock underneath it, instead of just being between layers of ice. What two discoveries prompted this conclusion

Based on what you know about the location of the earth in relation to the sun, why is this called the goldilocks zone in other galaxies? a. it's a region that exhibits a weak gravitational pull, thus maintaining a safe distance from the sun. b. it's an area that doesn't experience any major weather events that could cause mass extinctions. c. it's an area that's an optimal distance from the sun for potentially supporting life. d. it's a region that's unaffected by asteroid or meteor impacts.
