Are we alone?

Look: 6 Earth-like planets JWST will study for clues to life

We might not find aliens, but these targets will bring us even closer to an encounter.



There’s no shortage of Earth-sized worlds in the universe.

But finding one that can host life is one of the greatest challenges astronomers face as we probe deeper into space.

The James Webb Space Telescope (JWST) will offer an unprecedented look at distant exoplanets.

We don’t know exactly what we’ll find out there, but astronomers already plan to investigate several rocky worlds similar to the one we live on.
