How Far can the Hubble Space Telescope See?
We mentioned earlier about Galileo Galilei’s discovery of the Galilean moons of Jupiter thanks to his written works about his observations with his telescope. His discovery became a strong proof for the Heliocentric Universe model, and it paved the way for science that is based on careful calculations and observations.
Nowadays, our technology has gone a long way. Many different types of telescopes have given us opportunities to study the Universe in its earlier stages. Most astronomers call this as “looking back in time”. But how do telescopes look back in time?
We want you to watch the video below explaining how does the Hubble Space Telescope (HST) look back in time. Other telescopes observe the early universe using the same concept explained in the video.
This is an additional video, hosted on YouTube.
