Hubble Trivia: 13) What does Hubble’s infrared vision help astronomers see?

The video explains how infrared light allows us to see through dust clouds and observe cooler objects like planets. It highlights the ability of longer wavelengths to bend around obstacles, enabling us to view inside opaque clouds such as the Orion and Eagle Nebulae. Additionally, the video discusses the importance of infrared in observing distant galaxies, which appear to be moving away due to the universe's expansion. The light from these galaxies is stretched, shifting from visible to infrared wavelengths, necessitating the use of infrared telescopes to study them.

How do longer wavelengths of light interact with dust clouds?

What is the significance of the Orion Nebula and the Eagle Nebula in infrared observations?

What role does infrared light play in observing distant galaxies?

Explain how the expansion of the universe affects the light we receive from distant galaxies.

Why is an infrared telescope necessary to observe the first galaxies?
