Question 1

Why are astronomers called "light detectives"?

They look for life on other planets.

They build satellites to explore the solor system.

They carefully study how the sun's rays reflect off of objects.

They look for patterns in the stars to predict the future.

Question 2

It compares the orbits of different planets.

It compares two images to show movement.

It compares the brightness of two stars.

It compares distance between two objects.

Question 3

The CIT computers superimpose the images on top of each other.

The astronomers analyze the data and track movement.

A 161 camera is mounted to the telescope.

In 2003, the team discovers a slow moving bright shape.

Question 4

They discovered Pluto.

They calculated that Eris takes 560 to orbit the sun.

They believe there could be more dwarf planets in the Kuiper belt.

They thought Eris was much larger than it was.

Question 5

They created the blink comparator to look for moving objects.

They created a method of superimposing images on top of each other.

They demoted Pluto to a "dwarf planet".

They could see that Eris was about the same size as Pluto.
