Why These Two Planets SHOULD Be the Same

The video explores the differences in atmospheres between two exoplanets, WASP 67 B and HAT P38 B, despite their similar mass, size, and distance from their stars. It highlights the challenges in studying exoplanet atmospheres and the surprising findings of clouds and metallicity. The video discusses potential reasons for these differences, such as formation conditions or evolutionary events, and emphasizes the need for updated models to predict exoplanet atmospheres.

What is the main similarity between WASP 67 B and HAT P38 B?

• They are both terrestrial planets.

• They have similar mass and size.

• They orbit the same star.

• They have the same atmospheric composition.

What technique do astronomers use to study the atmospheres of exoplanets?

• Direct imaging

• Transmission spectroscopy

• Gravitational lensing

• Astrometry

What challenge do clouds present when studying exoplanet atmospheres?

• They cause the planet to emit more light.

• They make the planet's orbit unstable.

• They obscure the signals of atmospheric compounds.

• They increase the planet's temperature.

What is one possible reason for the atmospheric differences between WASP 67 B and HAT P38 B?

• They have different orbital periods.

• They were formed under different conditions.

• They are located in different galaxies.

• They have different core compositions.

Why is further study of exoplanet atmospheres important?

• To confirm the existence of life on other planets.

• To refine models predicting atmospheric characteristics.

• To find new habitable planets.

• To determine the age of the universe.
