Guest Speaker: Junellie Gonzalez Quiles, PhD Candidate, Johns Hopkins University.
Summary:
In this video, Junellie explains how astronomers use different techniques, such as the transit technique, for detecting and confirming the existence of exoplanets. Exoplanets can be categorized into Terrestrial-like, Neptune-like, Gas giants, etc. There is also a Super-Earth category for bigger and more massive Earth-like exoplanets. Astronomers use spectroscopy to study the chemical composition of the atmosphere of exoplanets as they transit in front of their stars. Using these techniques, astronomers are trying to identify planets in the habitable zone, i.e., planets at the right distance from their stars to have liquid water. Junellie uses the geological processes of the planets/moons of the solar system to understand similar processes in exoplanets.
This video will help you understand how astronomers use different techniques to study exoplanets and try to identify those in the habitable zone. We hope you enjoy it!
