One way of observing distant planets is by blocking out the light of their stars, similar to how we’d block out the Sun with our hands to see something nearby in the sky. Space telescopes like Hubble and Webb use precise devices inside the observatory to block the star’s light, called coronagraphs, allowing them to see dimmer exoplanets—as shown in this animation. Three of Webb’s instruments have their own coronagraphs, along with a host of other neat observing tools: https://webbtelescope.pub/3
