Why looking at the universe with only our eyes is not enough
For most of history, humanity relied solely on visible light to study the cosmos. This video explains how modern multiwavelength astronomy unlocks hidden secrets by observing radiation across the entire electromagnetic spectrum, revealing objects that remain invisible to the naked eye.
Until the 20th century, our understanding of space was limited to the narrow sliver of electromagnetic radiation visible to human sight. By developing technology to collect radiation outside this range, astronomers have gained a far more comprehensive view of the universe.
Dr. Padi Boyd discusses the future of this field and the critical role of the Hubble Space Telescope in uncovering cosmic mysteries. Different wavelengths reveal unique aspects of an object's composition and behavior, meaning that what appears dark or empty in one part of the spectrum may be vibrant and active in another.
