The video explores the Andromeda galaxy and the Hubble Space Telescope's role in astronomy. Hubble, launched in 1990, offers clearer space images than ground telescopes. It has revealed star formation processes, stellar deaths, and helped determine the universe's age and expansion rate, estimated at 13.8 billion years. Hubble continues to enhance our understanding of the universe's formation.

What is one of the main advantages of the Hubble Space Telescope compared to ground-based telescopes?

• It is closer to the stars.

• It can observe the universe without atmospheric interference.

• It is larger than any ground-based telescope.

• It was launched by a space shuttle.

What phenomenon occurs when a cloud of gas and dust collapses?

• A supernova occurs.

• A new star is born.

• A black hole is formed.

• A galaxy is created.

What happens when a star reaches the end of its life?

• It turns into a planet.

• It fades away quietly.

• It explodes in a tremendous explosion.

• It becomes a black hole.

How did Hubble help scientists determine the age of the universe?

• By analyzing the color of stars.

• By counting the number of galaxies.

• By observing the speed of galaxy expansion.

• By measuring the temperature of stars.

What is the estimated age of the universe according to Hubble's findings?

• 15.2 billion years

• 12.3 billion years

• 10.5 billion years

• 13.8 billion years
