CMB Sky Sphere
Interactive 3D-style canvas simulation: CMB Sky Sphere.
Monopole T₀2.725 K
Dipole±3.362 mK
Fine anisotropyδT/T ≈ 10⁻⁵
A mock Planck-style sky: a ±3.36 mK kinematic dipole dominates the raw map; removing it reveals δT/T ≈ 10⁻⁵ Sachs–Wolfe blobs, and the fine mode shows the acoustic-scale speckle. Drag to rotate.
