Exploring the Trappist-1 System

What is the name of the star around which the seven Earth-like planets were discovered?

• Alpha Centauri

• Proxima Centauri

• Trappist-1

• Kepler-22

How many Earth-sized planets were found around Trappist-1?

• Nine

• Seven

• Five

• Three

Why is the discovery of Earth-sized planets around Trappist-1 particularly exciting?

• They are Earth-sized and potentially habitable.

• They are all gas giants.

• They are closer to us than any other exoplanets.

• They are the first planets discovered outside our solar system.

What is one of the key factors in determining the habitability of a planet?

• Distance from the Milky Way center

• Size of the planet

• Presence of liquid water

• Presence of a magnetic field

What technique is used to detect the presence of an atmosphere on exoplanets?

• Analyzing magnetic fields

• Observing transit light curves

• Measuring gravitational waves

• Detecting radio signals

What upcoming telescope is expected to enhance our understanding of exoplanet atmospheres?

• Chandra X-ray Observatory

• Spitzer Space Telescope

• Hubble Space Telescope

• James Webb Space Telescope

What is a potential effect of a planet being tidally locked to its star?

• It has a strong magnetic field.

• It has a very short day-night cycle.

• One side is always in daylight, the other in darkness.

• It experiences extreme seasonal changes.

How might life on a tidally locked planet differ from life on Earth?

• Life would be photosynthetic.

• Life would be aquatic.

• Life would not rely on light cycles.

• Life would be nocturnal.

What is a mean-motion resonance in planetary systems?

• A type of light reflection pattern

• A type of magnetic field interaction

• A resonance in the planet's atmosphere

• A gravitational interaction causing planets to orbit in sync

What is the SPECULOOS survey aiming to discover?

• The age of the universe

• The presence of black holes

• The commonality of systems like Trappist-1

• The speed of light in different galaxies
