1. How do space observatories work?

Space observatories are equipped with advanced telescopes and instruments that are specially designed to capture various forms of light from outer space. They are launched into space to avoid the distortion caused by Earth’s atmosphere, allowing for clearer and more detailed observations.

2. What is the difference between a ground-based telescope and a space observatory?

Ground-based telescopes are located on Earth’s surface and are impacted by atmospheric conditions, such as air turbulence and light pollution. Space observatories, on the other hand, are positioned above the Earth’s atmosphere, providing unimpeded views of the universe and clearer observations.

3. How do space observatories contribute to scientific research?

Space observatories provide scientists with invaluable data about the universe, allowing them to study celestial objects, measure distances between galaxies, explore planetary systems, and investigate various astrophysical phenomena. They help us to understand the origins of our universe and shed light on fundamental questions about its structure and evolution.

4. Can space observatories discover new planets?

Yes, space observatories have played a key role in the discovery of numerous exoplanets (planets outside our solar system). By detecting tiny variations in the light emitted by stars, they can identify the presence of orbiting planets and analyze their characteristics.

5. Are there plans for future space observatories?

Absolutely! Scientists and space agencies are continually working on developing new and more advanced space observatories. The upcoming James Webb Space Telescope, slated to launch in 2021, promises to revolutionize our understanding of the universe with its enhanced capabilities and cutting-edge technology.
