This animation by @CSInst fellow Dmitry Savransky shows the history of the discovery of currently known #exoplanets. Different symbols represent different detection methods, and concentric, nested symbols represent multi-planet systems. [1/6]https://www.youtube.com/watch?v=GzNNg-MBVes&ab_channel=DmitrySavransky …
The detection methods are described here: https://en.wikipedia.org/wiki/Methods_of_detecting_exoplanets …. Each point is plotted at the location of the host star in the sky in equatorial coordinates. The audio assigns different notes to different detection methods. [2/6]
Turn up the volume when watching the video! C for transits, E for RV, G for microlensing, B flat for Imaging, and D for other, with octave inversely proportional to planet mass (lower notes indicate larger planets, higher notes indicate smaller ones) https://www.youtube.com/watch?v=GzNNg-MBVes&ab_channel=DmitrySavransky … [3/6]
Data were drawn from the NASA Exoplanet Archive https://exoplanetarchive.ipac.caltech.edu/index.html [4/6]
