Dropdown

How do we know what ​

Select answer

are in stars? Astronomers use a spectroscope to see what ​

Select answer

that a star has in its emission spectrum. Because each element has a unique ​

Select answer

, or different light ​

Select answer

, we can identify unknown elements by matching the spectrum lines we see with the spectrum of ​

Select answer

elements.

Multiple Choice

According to the video, what did nearly everyone believe about the Universe in 1920?

• The universe is unchanging.

• The universe is expanding and changing.

• The Universe is shrinking rapidly.

• The Universe is getting brighter.

Multiple Choice

How did Edwin Hubble measure how far away stars are from Earth?

• He constructed the Hubble Space Telescope to make measurements from space.

• He graphed the different spectrum data gathered from every star in the galaxy.

• He shined a laser at each star and measured how long it took for the light to bounce back.

• He compared the apparent brightness of Cepheid variables with their known actual brightness.

Multiple Choice

What did Hubble discover about the Milky Way Galaxy?

• All stars are part of the Milky Way Galaxy.

• There are other galaxies of stars outside the Milky Way Galaxy.

• There are singular stars that exist outside of galaxies.

• The Milky Way Galaxy is a million light years across.

Multiple Choice

What did Hubble discover about all of the galaxies he observed?

• All galaxies are moving away from each other.

• All galaxies are moving towards each other.

• Some galaxies are moving away from us, and other galaxies are moving towards us.

• Each galaxy is collapsing in on itself.

Multiple Choice

What did Hubble discover about distant galaxies?

• Distant galaxies are moving slower than nearer galaxies.

• Distant galaxies are moving faster than nearer galaxies.

• There is no correlation between distance and velocity of galaxies.

• All galaxies are moving at random velocities.

Multiple Choice

What is one conclusion you can make about the expanding universe?

• If everything is expanding, if you run it backwards, then everything started at a singular point of singularity.

• If everything is expanding, the Universe will eventually pop like a balloon.

• The Universe will expand until it reaches a pre-determined size and then remain constant.

• The Universe will expand until all matter it contains becomes concentrated in a giant supermassive black hole.
