The Cosmic Microwave Background (CMB) is remnant electromagnetic radiation from the epoch of recombination. It is the most ancient important source of data about the early universe and the key to unlocking the mysteries of the Big Bang and the structure of time and space. Spurred on by a wealth of satellite data, intensive investigations in the past few years have resulted in many physical and mathematical results to characterise CMB radiation. It can be modelled as a realisation of a homogeneous Gaussian random field on the sphere. But, what does any of this matter for statisticians if they cannot play with the CMB data in their favourite programming language?A new R package, rcosmo, provides easy access to the CMB data and various tools for exploring geometric and statistical properties of the CMB. This talk will be a quick introduction to rcosmo by one of its developers, followed by an invitation for discussions and suggestions.This research was supported under the Australian Research Council's Discovery Project DP160101366.
