Why Infrared Light Reveals the Invisible Universe

Most of the universe is invisible to our eyes — not because it isn’t there, but because we can’t see the kind of light it emits.

In this video, we explore how infrared light allows astronomers to reveal hidden stars, planets, and galaxies that remain unseen in visible light. From dusty star-forming regions to the earliest galaxies in the universe, infrared helps scientists look deeper into space and further back in time.

You’ll learn:

Why human vision is limited to visible light

What infrared light really is

How infrared passes through cosmic dust

Why modern space telescopes rely on infrared observations
