TED: How the James Webb Space Telescope will unfold the universe | John C. Mather

The video explores the origins of the universe, starting with the Big Bang and the role of stars in creating elements. It discusses the Hubble Space Telescope's discoveries and the need for the more advanced James Webb Space Telescope. The video details the engineering marvel of the James Webb Telescope, its launch, and deployment in space. It highlights the telescope's potential to explore the solar system, including Mars, Europa, and Titan, and its ability to detect exoplanets with potential for life.

What is the significance of the cosmic microwave background radiation?

• It is the heat emitted by the sun.

• It is the radiation from black holes.

• It provides evidence of the Big Bang and early universe conditions.

• It is the light emitted by the first stars.

Why was the James Webb Space Telescope developed?

• To explore the surface of Mars.

• To monitor weather patterns on Earth.

• To observe the most distant galaxies and study the early universe.

• To replace the Hubble Space Telescope due to its age.

What was a major engineering challenge in launching the James Webb Space Telescope?

• Developing a telescope that could be controlled by astronauts.

• Building a telescope that could withstand the sun's heat.

• Designing a telescope that could fit into a rocket.

• Creating a telescope that could operate underwater.

Where is the James Webb Space Telescope positioned for its operations?

• In orbit around Mars.

• In orbit around the Earth.

• On the surface of the Moon.

• At LaGrange Point 2, a stable point in space.

What is one of the goals of the James Webb Space Telescope regarding exoplanets?

• To measure the gravitational pull of exoplanets.

• To analyze the atmospheres of exoplanets for signs of life.

• To land on exoplanets and collect samples.

• To capture images of exoplanets' surfaces.

What makes Titan an interesting target for the James Webb Space Telescope?

• It has a thick atmosphere and liquid hydrocarbon lakes.

• It has a surface covered in liquid water.

• It is the closest moon to the Sun.

• It is the largest moon in the solar system.

What is a unique feature of Europa that interests scientists?

• Its volcanic activity.

• Its thick atmosphere.

• Its liquid ocean beneath an ice crust.

• Its high surface temperature.
