Hubble Observes Atmospheres of TRAPPIST-1 Exoplanets in the Habitable Zone

The Trappist-1 system, located 40 light-years away, contains seven Earth-sized planets, three of which are in the habitable zone. Hubble observations suggest these planets lack thick hydrogen-rich atmospheres, indicating they may be rocky. Future telescopes, including the James Webb Space Telescope, aim to further study these planets' atmospheres and potential habitability. The Trappist-1 system offers a unique opportunity to understand terrestrial exoplanets.

What is the significance of the Trappist-1 system in the search for habitable planets?

• It is the closest star system to Earth.

• It is the only system with confirmed life.

• It contains seven Earth-sized planets, three in the habitable zone.

• It has the largest number of gas giants.

What did Hubble's observations reveal about the atmospheres of the Trappist-1 planets?

• They are mostly gas giants.

• They have no atmospheres at all.

• They are likely rocky planets.

• They have thick hydrogen-rich atmospheres.

Which planets in the Trappist-1 system are located in the habitable zone?

• Planets G and H

• Planets E and F

• Planets D and E

• Planets B and C

What is the role of the James Webb Space Telescope in studying the Trappist-1 system?

• To observe the planets in the visible light spectrum.

• To confirm the existence of life on the planets.

• To further characterize the atmospheres in the far infrared.

• To measure the distance of the Trappist-1 system from Earth.

Why is the Trappist-1 system considered a unique opportunity for studying exoplanets?

• It has the most massive star known.

• It is the first system discovered by the Hubble Telescope.

• It is the only system with more than five planets.

• It provides a chance to study Earth-sized exoplanets in detail.
