Hubble Trivia: 6) What Has Hubble Helped to Reveal About the Expansion of the Universe?

The Hubble Space Telescope was initially launched to refine the measurement of the universe's expansion rate. It has successfully done so, but recent findings show that the expansion rate is accelerating, contrary to earlier beliefs. Initially, the universe's expansion was decelerating. Hubble is now used to further refine these measurements and compare them with predictions from other telescopes. Current research reveals discrepancies between expected and actual measurements, highlighting Hubble's role in uncovering new mysteries of the universe.

What was the primary goal of the Hubble Space Telescope when it was launched?

• To study the sun's activity

• To find new planets in our solar system

• To measure the expansion rate of the universe

• To explore the surface of Mars

What unexpected discovery did scientists make about the universe's expansion?

• It is shrinking

• It has stopped

• It is accelerating

• It is slowing down

How did scientists determine that the universe's expansion rate is not uniform?

• By analyzing Earth's atmosphere

• By measuring the moon's orbit

• By studying distant galaxies

• By observing the sun

What is Hubble currently being used for in terms of the universe's expansion?

• To study black holes

• To find new stars

• To refine the expansion rate and compare it with other measurements

• To predict weather patterns

What has the comparison of Hubble's measurements with other telescopes revealed?

• A decrease in expansion rate

• A perfect match

• A discrepancy

• No new information
