[00:00:00]Imagine a telescope, not just peering at distant skies, but reading the very rocks of an alien world.

[00:00:07]The James Webb Space Telescope did exactly that with LHS 3844b, a rocky super-Earth orbiting a nearby red dwarf.

[00:00:19]Instead of gases, Webb detected signs of a dry basaltic surface, silicate minerals heated to thousands of degrees, and reflecting infrared fingerprints.

[00:00:30]This revealed a world scorched by its star, likely lacking an atmosphere, and resembling volcanic landscapes on Earth.

[00:00:39]By analyzing the light reflected from its surface, Webb transformed exoplanet study from atmosphere to geology, opening a new era in understanding alien worlds.
