Explanations: answer key for all 10 questions

Q1: Why are telescopes placed in space?
Answer: To avoid the atmosphere's blurring and blocking
Some light cannot pass through air.
Q2: When was the Hubble Space Telescope launched?
Answer: 1990
It orbits about 540 km up.
Q3: What problem did Hubble's first images reveal?
Answer: A flawed mirror
Astronauts fixed it in 1993.
Q4: Where does the James Webb Space Telescope orbit?
Answer: Around the L2 point, 1.5 million km away
It stays cold behind a sunshield.
Q5: How many gold-coated segments make up Webb's main mirror?
Answer: 18
It is 6.5 meters across.
Q6: Which NASA telescope observes X-rays?
Answer: Chandra
It studies black holes and supernova remnants.
Q7: Which NASA telescope studied the infrared universe from 2003 to 2020?
Answer: Spitzer
It saw through dust.
Q8: What is ESA's Gaia mission mapping?
Answer: Positions and motions of over a billion stars
It builds a 3D map of the Milky Way.
Q9: Who is the Hubble telescope named after?
Answer: Edwin Hubble
He showed the universe is expanding.
Q10: Which NASA wide-field telescope is named after the agency's first chief of astronomy?
Answer: Nancy Grace Roman Space Telescope
It is designed to survey dark energy and find exoplanets across huge areas of sky.

Space Telescopes Quiz – Eyes Above the Atmosphere

Earth's atmosphere blurs starlight and blocks X-rays, ultraviolet and much infrared light. Placing telescopes in space lets astronomers see the universe clearly across many wavelengths.

Hubble, launched in 1990, became one of the most productive scientific instruments ever after its mirror was repaired. NASA's Great Observatories also included Compton for gamma rays, Chandra for X-rays and Spitzer for infrared.

The James Webb Space Telescope, launched in 2021, sees deeper into the infrared than any before, revealing early galaxies and exoplanet atmospheres. Missions like Gaia, Kepler and TESS map stars and find planets.
