skychart

Will's pick this week is skychart by Emmanuel Farhi.

This submission leverages object-oriented programming to plot celestial objects visible to a ground-based observer. Create an object, define your longitude and latitude, define your time of observation, and plot away. This is what I got for Washington, DC midday. I cross-referenced the output with an app on my phone and found that skychart is quite accurate.



What I find especially novel is that this tool doesn't just show you celestial bodies visible to the naked eye. Instead, you get over 50,000 objects, which you can begin to appreciate if you zoom the figure:



This is the second pick in a row that I've selected that was created by someone named Emmanuel. Are there any more of you out there with ingenious contributions? Can we go for the hat trick?
