TED: The marvels and mysteries revealed by the James Webb Space Telescope | Heidi Hammel and Nadia Drake

The video discusses the James Webb Space Telescope (JWST), its design, capabilities, and differences from the Hubble Telescope. It highlights JWST's role in exploring the universe, studying galaxies, stars, and planets, and its potential to find life beyond Earth. The video also covers the international collaboration involved in JWST's creation and deployment, the use of spectrographs in astronomy, and personal insights from an astronomer on her journey and the unanswered questions in the field.

What is one of the main differences between the James Webb Space Telescope and the Hubble Space Telescope?

• JWST has a single-piece mirror.

• JWST is located in low Earth orbit.

• JWST focuses on the infrared spectrum.

• JWST is smaller than Hubble.

Why was the sunshield crucial for the James Webb Space Telescope?

• To shield it from the sun's heat.

• To help it fold up for launch.

• To keep the telescope warm.

• To protect it from space debris.

What is the significance of the L2 point for the JWST?

• It is closer to Earth for easy maintenance.

• It provides a stable and cold environment.

• It allows the telescope to orbit the sun.

• It is a point where the telescope can refuel.

What does the JWST's ability to observe in the infrared spectrum allow scientists to do?

• Capture high-resolution images of the sun.

• Detect radio waves from other galaxies.

• Measure the temperature of distant stars.

• See through cosmic dust to observe star formation.

What is the Trappist-1 system known for?

• Having the largest known star.

• Having no planets in the habitable zone.

• Containing several Earth-sized planets.

• Being the closest star system to Earth.

What is one reason scientists are interested in Jupiter's moon Europa?

• It is the largest moon in the solar system.

• It has a thick atmosphere.

• It may have a subsurface ocean.

• It has active volcanoes.

What role does the JWST play in the search for extraterrestrial life?

• It sends probes to distant planets.

• It communicates with potential alien civilizations.

• It analyzes the atmospheres of exoplanets for signs of life.

• It can directly capture images of alien life forms.

What unique feature does Triton, Neptune's moon, possess?

• It has a thick, breathable atmosphere.

• It is the smallest moon in the solar system.

• It has active cryo volcanoes.

• It orbits in the same direction as Neptune.

What inspired the speaker's interest in astronomy?

• A family member who was an astronomer.

• A teacher's encouragement to apply to MIT.

• A childhood telescope gift.

• A fascination with the moon.

What is one of the unanswered questions in astronomy that intrigues the speaker?

• The speed of light in different galaxies.

• The number of black holes in the universe.

• The formation of the first stars and galaxies.

• The exact size of the universe.
