Above the Clouds: Space Telescopes Studying Exoplanets

Escaping the blur of Earth's atmosphere. By launching our "eyes" into the vacuum of space, we can detect the tiny dip in light from a planet orbiting a star trillions of miles away. This space telescopes...

Questions: 20 | Attempts: 12 | Last updated: Feb 20, 2026

Sample Question 1
Why are space telescopes studying exoplanets more effective at atmospheric characterization than ground-based observatories?

They are closer to the target stars

They avoid the absorption and turbulence of Earth's atmosphere

They have larger mirrors than any ground telescope

They do not require electricity to function

They can travel to the exoplanets

Sample Question 2
The James Webb Space Telescope (JWST) primarily uses infrared wavelengths to perform exoplanet observations because planets are brighter in the infrared relative to their stars.

True

False

Sample Question 3
Which of the following molecules are commonly targeted during exoplanet atmosphere studies using transmission spectroscopy?

Water Vapor (H2O)

Methane (CH4)

Carbon Dioxide (CO2)

Liquid Iron

Nitrogen Gas (N2)
