Why build a 4-meter diameter ground-based telescope? The Electromagnetic Spectrum and Absorption by the Earth’s Atmosphere: Wavelength of light
Why build a 4-meter diameter ground-based telescope? The Electromagnetic Spectrum and Absorption by the Earth’s Atmosphere: Wavelength of light Light from outer space cannot penetrate below this altitude.
Why build a 4-meter diameter ground-based telescope? The Electromagnetic Spectrum and Absorption by the Earth’s Atmosphere: Wavelength of light Light from outer space cannot penetrate below this altitude. • Telescopes must be in space to observe at x-ray, ultra-violet, or far-infrared wavelengths: • Chandra X-Ray satellite • Hubble Space Telescope • Spitzer Infrared satellite
