These two photographs of the M82 Galaxy give an idea of the observable detail using (a) a ground-based telescope and (b) the Hubble Space Telescope. Visitor programs Canberra Deep Space Communication Complex 0.25 * wavelength (microns) / telescope diameter = angular resolution (arcsec) (m). | MRO Peter Erwin: well I think that given how the word is commonly used, its not a surprise that the OP found the use of higher in this context confusing. This instrument was used by the astronomer Asaph Hall to discover the two moons of Mars, Phobos and Deimos, in 1877. An expression for resolving power is obtained from the Rayleigh criterion. This renders the document in high contrast mode. By simply entering the Wavelength of the light and the Aperture diameter of the lens, the angular resolution calculator will display the corresponding Resolution. | VLBI, Astrophysics overview AIPS The image on the right has a fainter limiting magnitude. endstream endobj 75 0 obj<>/Metadata 7 0 R/PieceInfo<>>>/Pages 6 0 R/PageLayout/OneColumn/OCProperties<>/StructTreeRoot 9 0 R/Type/Catalog/Lang(EN-US)/LastModified(D:20090720085529)/PageLabels 4 0 R>> endobj 76 0 obj<>/PageElement<>>>/Name(HeaderFooter)/Type/OCG>> endobj 77 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/Properties<>/ExtGState<>>>/Type/Page>> endobj 78 0 obj<> endobj 79 0 obj<> endobj 80 0 obj[/ICCBased 95 0 R] endobj 81 0 obj[/Indexed 80 0 R 255 97 0 R] endobj 82 0 obj[/Indexed 80 0 R 255 99 0 R] endobj 83 0 obj[/Indexed 80 0 R 255 101 0 R] endobj 84 0 obj<> endobj 85 0 obj<> endobj 86 0 obj<> endobj 87 0 obj<> endobj 88 0 obj<>stream The right hand image from the more sensitive telescope reveals more and fainter stars and galaxies.
