What will happen when the Andromeda galaxy and the Milky Way galaxy collide sometime in the next four billion years?
They will merge to create an elliptical galaxy.
They will crash together and both explode.
The Milky Way will engulf the other galaxy.
Which of the following is going through "galactic cannibalism" or galaxy mergers?
How can astronomers tell where new star formation is happening in interacting galaxies?
By only using visible light
By locating dark spots in the galaxies
By finding areas with no gas or dust
By observing bright blue clusters
What type of galaxy is the Milky Way?

Elliptical
Irregular
Barred Spiral
How did scientists determine there was a black hole in the center of the Milky Way galaxy?
Observing stars orbiting around an invisible, massive object
Detecting strong radiowaves coming from the center of the galaxy
Directly photographing the black hole with a telescope
What are the most common type of galaxy?

Young & hot
Older & cooler

What statement best describes this image?
The Milky Way has never experienced any mergers or interactions with other galaxies
The Milky Way Galaxy has broken apart into smaller and smaller galaxies
The Milky Way Galaxy is the result of mergers between smaller galaxies
How can galaxies merge even though the universe is expanding?
The expansion of the universe stops completely near galaxies
Gravity between galaxies can overcome the expansion of space
Galaxies merge because the expansion of the universe reverses periodically
What did the Hubble Space Telescope reveal about areas of dark, "empty" sky?
Space really is an empty void
