As exoplanets pass in front of their star, they block some of the starlight. While it's not enough of a difference in brightness to see with our eyes, computers are great at noticing these small differences.

Resources to get you started in Exoplanet Watch

  1. Build Your Own Transit Lightcurve Activity

    • Get a quick introduction to explanets, how we observe transits, and what a transit lightcurve tells you in this hands-on activity from Sonoma State's Astronomy from Home (AfH) Project
    • AfH also provides a more detailed background on exoplanets
  2. MicroObservatory DIY Planet Search

    • ​Observe a transiting exoplanet using a robotic telescope
    • DIY Planet Search teaches you how astronomers perform multi-object photometry to extract the time-varying brightness of a transit from raw astronomical images
    • DIY Planet Search demonstrates the data reduction steps conducted with EXOTIC
  3. Try the Beginner Tutorial to learn how to use EXOTIC to make a light curve

    • Use Exoplanet Watch's official data reduction tool EXOTIC to analyze a sample dataset of the transiting exoplanet, HAT-P-32b, to produce your own transit lightcurve and measure this planet's transit depth and mid-transit time. Use the Beginner Tutorial to learn how EXOTIC works, then use the Standard version of EXOTIC to produce light curves with your own data sets.
