  This is a summary of the `Astronomy Perspective' of the 4th meeting on
'Statistical Challenges in Modern Astronomy' held at Penn State University in
June 2006. We comment on trends in the Astronomy community towards Bayesian
methods and model selection criteria. We describe two examples where Bayesian
methods have improved our inference: (i) photometric redshift estimation (ii)
orbital parameters of extra-solar planets. We also comment on the pros and cons
of Globalization of scientific research. Communities like Astronomy, High
Energy Physics and Statistics develop ideas separately, but also have frequent
interaction. This illustrates the benefits of 'comparing notes'.
