Exploring How Astronomers Study Distant Stars

What does the Hubble Space Telescope reveal when observing a small patch of sky?

• Individual stars only

• Galaxies containing billions of stars

• Planets in our solar system

• Only the Milky Way

Why is astronomy considered the oldest science?

• It involves complex equipment

• It predates agriculture and navigation

• It was founded in the 20th century

• It is not an observational science

What limits our ability to experiment in astronomy?

• The size of telescopes

• Lack of interest in the subject

• The vast distances in space

• The brightness of stars

How do astronomers determine the composition of stars?

• Using spectral rainbows

• Through direct sampling

• By touching the stars

• Listening to the stars

Why do astrophysicists use different kinds of telescopes?

• To detect light at various wavelengths

• Because one telescope is not enough

• To make the research more expensive

• For aesthetic reasons
