Ep. 118: Sky Surveys

December 8th, 2008

Episode 131 of 464 episodes

In the old days, astronomers had to beg for telescope time. They'd put together a proposal, convince observatories to gather data for them, crunch that data and release the results.

Anyone who wants can access the information through the Internet, download what they need to do real science. No telescope necessary. Let's look at the development of sky surveys, and how they're changing how astronomy gets done.
