![]() Also, larger telescope mirrors produce less scattering of light due to diffraction, which makes faint objects bright enough to detect. Astrometry deals with locating the central position of a known unresolved source, primarily a star. Also, larger telescope mirrors produce more scattering of light due to diffraction, which contributes to better angular resolution.ĭ) Larger telescope mirrors have a larger surface area and can therefore collect more light, which contributes to better angular resolution. ![]() Also, larger telescope mirrors produce less scattering of light due to diffraction, which contributes to better angular resolution.Ĭ) Larger telescope mirrors have a larger surface area and can therefore collect more light, which makes faint objects bright enough to detect.

If an astronomer observes under such conditions at visible wavelengths using a 2.4-meter telescope, the angular resolution is limited by O O O O turbulence in the Earth's atmosphere. Explain two reasons why astronomers are continually building larger and larger telescopesĪ) Larger telescope mirrors have a larger surface area and can therefore collect more light, which contributes to better angular resolution. Transcribed image text: The very best atmospheric conditions on Earth result in an angular resolution limit of about 0.4 arcseconds.
