Exploring the Depths of Space: The Legacy of the Hubble Space Telescope

The transcript discusses the Hubble Space Telescope's impact on astronomy, its maintenance history, and the challenges faced during its servicing missions. It highlights Hubble's final mission, which included significant repairs and upgrades. The document also covers Hubble's key discoveries, such as insights into star formation and galaxy structures, and its observations of nearby celestial bodies like Mars and the Moon. With no more servicing missions planned, Hubble's operational life is limited, and a replacement is not expected soon.

What was a key feature of the Hubble Space Telescope's design?

• It was the largest telescope ever built.

• It was designed for on-orbit repair.

• It was the first telescope to be launched into space.

• It was designed to be operated from the Moon.

What was the main reason for the Hubble's fourth service mission being the most ambitious?

• It involved the installation of a new telescope.

• It required the replacement of the power control unit.

• It was the first mission to the Hubble.

• It was conducted entirely by robots.

What did the Hubble Space Telescope reveal about the Carina Nebula?

• It is a single star system.

• It contains a mysterious complex structure.

• It is the closest nebula to Earth.

• It is composed entirely of dark matter.

What significant discovery did Hubble make about the Sombrero Galaxy?

• It is moving away from the Milky Way.

• It is located in the Andromeda Cluster.

• It is equivalent to 800 billion Suns.

• It is the largest galaxy in the universe.

What is unique about the interstellar gas in the outer regions of the spiral Galaxy Messiah 64?

• It rotates in the same direction as the inner regions.

• It rotates in the opposite direction to the inner regions.

• It does not rotate at all.

• It is composed entirely of hydrogen.

What challenge does Hubble face when capturing images of the Moon?

• The Moon is too far away.

• Hubble needs to take a mosaic of 130 pictures to cover the entire disk.

• Hubble cannot focus on objects within the solar system.

• The Moon is too bright for Hubble's sensors.

Why might the Hubble Space Telescope have only 18 months of useful life remaining?

• It is being moved to a new orbit.

• It is running out of fuel.

• It is being replaced by a new telescope.

• There are no more servicing missions planned.
