# How Can a Space Telescope Study an Exoplanet Without Seeing Its Surface?

When astronomers discuss the atmosphere or climate of a planet orbiting another star, what observations are they actually working from? At those distances, I assume a telescope usually cannot resolve the planet as a visible disk, let alone pick out clouds or terrain.

How do researchers distinguish information about the planet from the much brighter light of its star? I’d like to understand what measurements support claims about an **[exoplanet atmosphere](https://answers.mindstick.com/qa/114912/which-space-telescope-mission-aims-to-study-exoplanet-atmospheres-after-hubble)**, and where the limits of those measurements are.
