True or False? Earth and other planets and moons in the solar system have been (and are still) hit by objects like meteors, comets and asteroids?
- True
- False
Why is it difficult to detect exoplanets..?
- They are far away
- The light from the parent star is very strong
- They may not cross our line of sight from Earth
Radial velocity is a method to find exoplanets by..?
- Measuring the tiny wobble of a star caused by the pull of a planet
- Measuring changes in the light from a star as a planet moves in front
- Measuring changes in the movement of a star towards and away from Earth using the Doppler effect
Transit methods are used to find exoplanets by..?
- Measuring the tiny wobble of a star caused by the pull of a planet
- Measuring changes in the light from a star as a planet moves in front
- Measuring changes in the movement of a star towards and away from Earth using the Doppler effect
Astrometry is a method to find exoplanets by..?
- Measuring the tiny wobble of a star caused by the pull of a planet
- Measuring changes in the light from a star as a planet moves in front
- Measuring changes in the movement of a star towards and away from Earth using the Doppler effect
The habitable zone is also known as..?
- The Snow White zone
- The Goldilocks zone
- The Cinderella zone
The habitable zone is an area where..?
- Humans can build dwellings

- False
Scientists usually look for life elsewhere in the solar system where..?
- On terrestrial planets and moons
- There is evidence of past or present water.
- It is nice and warm
Which is NOT considered a theory for the origin of water on Earth..?
- Condensation when Earth formed
- Delivery from a comet

The Drake equation is a way to..?
- Measure the habitable zone on an exoplanet
- Estimate how many intelligent alien life forms exist that we could communicate with
- Count the number of male ducks on a pond
Which of these is a reason why contacting intelligent alien life is NOT a good idea..?
- Intelligent life may share knowledge about science that we have yet to discover
- Intelligent life may share advances in technology such as travel and communication.
- Alien forms of life could create new bacteria capable of killing all life
