Big Data in Space Science

<p>It seems like “big data” is everywhere these days. In planetary science and astronomy, we’ve been dealing with large datasets for a long time. So how “big” is our data? How does it compare to the big data that a bank or an airline might have? What new tools do we need to analyze big datasets, and how can we make better use of existing tools? What kinds of science problems can we address with these? I’ll address these questions with examples including ESA’s Gaia mission, NASA’s WISE mission, and NASA’s Planetary Data System, as well as some of my group’s work on multiwavelength studies of nearby galaxies. </p>
