Cuando usar Cosmic Microwave Background 3D Explorer

Use this explorer when you want to separate the monopole, dipole, and anisotropies of the CMB - and skip it when you want cosmic expansion or the blackbody spectrum instead.

• Classroom demos of the near-uniform 2.7255 K background and its tiny ripples
• Showing why one side of the sky looks warmer (our motion, the dipole)
• Connecting 18 microkelvin anisotropies to the seeds of galaxies

This is an educational visualization with an illustrative colour map and exaggerated anisotropies, not the actual Planck sky data.

Walk the controls in the step-by-step guide, or compare options in vs alternatives. Open the Cosmic Microwave Background 3D Explorer.
