Step 2
Step 4
Explain why some telescopes are located outside the Earth's atmosphere
Answer
Telescopes in space, such as Hubble and Compton, are above the atmosphere, avoiding issues like air pollution, weather, and light pollution. This allows them to capture clearer images and view wavelengths (gamma, X-rays, etc.) that cannot penetrate the Earth's atmosphere.
Step 5
Describe how modern telescopes have contributed to our understanding of the Universe
Answer
Modern telescopes, including space-based telescopes like Hubble, have revolutionized our understanding of the Universe by:
- Capturing clearer images: They avoid atmospheric distortion, allowing for more detailed observations.
- Exploring various wavelengths: They enable observation in gamma rays, ultraviolet, and infrared, expanding our knowledge beyond visible light.
- Long-term observations: They can monitor celestial phenomena over extended periods, aiding in studying cosmic events and the structure of the Universe.
- Mapping the Universe: They contribute to mapping galaxies, understanding dark matter and dark energy, and exploring the formation and evolution of cosmic structures.
