If you were given a spacecraft that could travel at light speed and get you to any other planet, where would you go? Well, astronomers picked the best 45 exoplanets out of the 6,000 that we identified. It made me wonder what these planets are like and how you measure what’s a good “fit?” Let’s take a look and learn more about how you identify a habitable world! How did we select these 45 Exoplanets? Lucky for us, we have some great telescopes orbiting Earth. One of them is a European Space Agency (ESA) telescope called Gaia. Data to select these exoplanets came from this telescope, as well as a catalog of all the other previous exoplanets discovered. For this, we use the NASA Exoplanet Archive (NEA). We have our data sources. Next, what exactly are we looking for? Exoplanets that orbit in the habitable zone (HZ) Exoplanets that have similar radiation levels to...
