37:29Now PlayingIs Earth going to evaporate? Neil deGrasse Tyson and comedian Chuck Nice learn about exoplanet discovery, planetary evaporation, biosignatures and technosignatures with astrophysicist Anjali Tripathi.
What is our most studied planet? Learn about Anjali’s time as a White House Fellow and her work with the US Department of Agriculture and climate change. How does NASA give insights on Earth? What can satellites do for you? Plus, we answer audience questions: are exoplanets evaporating?
What is the likelihood of other intelligent life? We discuss intelligent life on Earth and the likelihood of finding life elsewhere in general. Discover spectroscopy, how we learn about the composition of distant exoplanets, and what JWST is discovering about exoplanets. Would we be able to eat and digest life from other planets? Would you want to eat an alien?
Is there a minimum and maximum size for rocky planets to be habitable? We explore planet density, gravity on Mars, and what defines a “Super-Earth.” We break down the different types of biosignature gasses, technosignature gasses, and how pollution could help us find aliens. Are there some gasses that only life can make?
