Searching for exoplanets

In this section, we'll begin the search for exoplanets by analyzing the Exoplanets dataset. We'll provide historical context for the discovery of exoplanets before attempting to detect them via plotting and observing light graphs. Plotting time series is a valuable machine learning skill that may be used to gain insights into any time series datasets. Finally, we'll make initial predictions using machine learning before revealing a glaring shortcoming.

Historical background

Astronomers have been gathering information from light since antiquity. With the advent of the telescope, astronomical knowledge surged in the 17th century. The combination of telescopes and mathematical models empowered 18th-century astronomers to predict planetary locations and eclipses within our own solar system with great precision.

In the 20th century, astronomical research continued with more advanced technology and more complex mathematics. Planets revolving...
