Space Telescopes
Space telescopes are advanced astronomical instruments placed in orbit around Earth or other celestial bodies to observe the universe beyond the interference of our planet’s atmosphere. By operating in space, these telescopes can capture clearer and more detailed images across various wavelengths, such as visible light, infrared, and X-rays. This allows scientists to study distant stars, galaxies, and cosmic phenomena, greatly expanding our understanding of the cosmos.

- Identify famous space telescopes and the discoveries they've enabled.
❓ Frequently Asked Questions
What is a space telescope?
A telescope placed in orbit around Earth or another body to observe the universe beyond Earth's atmosphere, providing clearer images by avoiding atmospheric distortion.
Why are space telescopes important for astronomy?
They offer sharper images, access to wavelengths blocked by the atmosphere, and long, uninterrupted observation times.
Which wavelengths can space telescopes observe, and why?
They can observe visible, infrared, and ultraviolet light, and some missions also target X-ray or radio wavelengths. Space avoids atmospheric absorption and scattering, enabling these observations.
Name a famous space telescope and its primary focus.
Hubble Space Telescope — optical and near-ultraviolet observations; James Webb Space Telescope — infrared observations.
