Whenever I read about what astronomers do, I feel puzzled. My puzzlement is caused by the stories told about methods used in the quest to measure the size of the Universe and the rate at which billions of galaxies in the Universe are moving away from each other and from our galaxy and therefore our planetary system.

The latest article by Dennis Overbye, a talented science writer, in the NY Times this morning tells the story of the latest happenings in this seemingly never ending quest for better precision. The notion of exact science doesn’t seem to fit this quest, which boils down to reducing the % of error in results.

There are several links below that offer more information about the Universe and efforts to understand it better. If you want to investigate weird click on the last link to the master explainer of cosmological things, Sean Carroll, the cosmologist.

IMHO one of the very neat things about astronomy is the dazzling photography connected with it.
