Step 2
Step 4
Explain why some telescopes are located outside the Earth’s atmosphere.
Answer
Telescopes in space, like Hubble and Compton, are positioned above the Earth's atmosphere, allowing them to avoid issues such as air pollution, clouds, and weather. This ensures clearer images and reduces distortion, enabling scientists to observe celestial phenomena more effectively than telescopes on the ground.
Step 5
Describe how modern telescopes have contributed to our understanding of the Universe.
Answer
Modern telescopes have vastly improved our understanding of the Universe through enhanced imaging capabilities and the ability to observe a wide range of electromagnetic spectrum wavelengths. They have enabled astronomers to study distant galaxies, identify exoplanets, and detect cosmic phenomena that were previously undetectable. Furthermore, space telescopes help eliminate atmospheric interference, providing clearer and more detailed views of celestial bodies, thus contributing to significant discoveries and advancements in astrophysics.
