KnowraPlanck satelliteLinked fromLinked fromThe 24 pages that link to Planck satellite, each with the reason it gives.All 24Broader topic 10Related 10Compared with 4Dark matterRelated: Its precision measurements helped determine the cosmic dark matter abundance.Recombination (cosmology)Related: Its precise background measurements constrain the timing and duration of recombination.Primordial gravitational wavesRelated: Planck's measurements of polarized dust helped reassess claims of an inflationary B-mode detection.Herschel Space ObservatoryRelated: It shared Herschel’s launch and orbit, but studied much shorter wavelengths and the early universe.John C. MatherRelated: Planck refined the measurements COBE first established at far greater angular resolution.CMB cold spotRelated: Its higher-resolution maps enabled detailed checks of the spot’s properties.Primordial fluctuationsRelated: Its measurements tightly constrained the amplitude and scale dependence of primordial fluctuations.Dark flowRelated: Planck data enabled later tests of the proposed signal.Inflationary epochRelated: Its precise measurements constrain the spectral shape and amplitude of inflationary perturbations.Shape of the universeRelated: Its measurements place strong constraints on curvature and primordial patterns.
