Step 4
Explain why some telescopes are located outside the Earth’s atmosphere.
Answer
Telescopes in space avoid atmospheric interference, such as air and light pollution, allowing for clearer images and a wider field of view. They can also observe wavelengths that are blocked by the atmosphere on Earth, such as gamma rays and infrared.
Step 5
Describe how modern telescopes have contributed to our understanding of the Universe.
Answer
Modern telescopes have significantly enhanced our understanding of the Universe through various advancements. Firstly, space telescopes, like the Hubble, provide clear images free from atmospheric distortion, enabling detailed observations of galaxies, stars, and celestial phenomena.
Moreover, telescopes that capture a range of electromagnetic waves—from radio to gamma rays—offer insights into different aspects of cosmic events, such as the life cycles of stars and the formation of black holes.
Advanced technology allows these telescopes to track distant objects and phenomena over time, contributing to discoveries such as the expansion of the Universe and the existence of exoplanets. Thus, modern telescopes have become essential tools for astrophysics, leading to a deeper comprehension of the cosmos.
