Our eyes in the sky. Test your knowledge on the revolutionary instruments peering into the deep universe.
The Hubble Space Telescope, launched in 1990, revolutionized astronomy by orbiting above Earth's atmospheric distortion. For over three decades, Hubble delivered unparalleled views in visible and ultraviolet light, allowing scientists to precisely measure the universe's expansion, observe distant galaxies, and capture breathtaking images of nebulae and star nurseries. Its iconic contributions fundamentally reshaped our understanding of the cosmos and inspired millions with its stunning visuals.
Building on Hubble's legacy, the James Webb Space Telescope (JWST) launched in 2021, opening a new window onto the universe primarily through infrared light. Positioned millions of miles from Earth, Webb's colossal, gold-coated mirror is optimized to peer through cosmic dust, reveal the very first galaxies formed after the Big Bang, and analyze exoplanet atmospheres for biosignatures. These two magnificent observatories, each a triumph of engineering, offer complementary perspectives, continuously pushing the boundaries of our cosmic knowledge from the dawn of time to the potential for life beyond our solar system.

Correct Answer: To avoid the blurring and distortion caused by Earth's atmosphere
💡 Did you know Earth's atmosphere not only blurs visible light but also completely absorbs certain wavelengths like X-rays and gamma rays, making space telescopes essential for observing the full electromagnetic spectrum?
