Query: Astronomical imaging: The theory of everything   We are developing automated systems to provide homogeneous calibration
meta-data for heterogeneous imaging data, using the pixel content of the image
alone where necessary. Standardized and complete calibration meta-data permit
generative modeling: A good model of the sky through wavelength and time--that
is, a model of the positions, motions, spectra, and variability of all stellar
sources, plus an intensity map of all cosmological sources--could synthesize or
generate any astronomical image ever taken at any time with any equipment in
any configuration. We argue that the best-fit or highest likelihood model of
the data is also the best possible astronomical catalog constructed from those
data. A generative model or catalog of this form is the best possible platform
for automated discovery, because it is capable of identifying informative
failures of the model in new data at the pixel level, or as statistical
anomalies in the joint distribution of residuals from many images. It is also,
in some sense, an astronomer's "theory of everything".
