Among the primary goals of the James Webb Space Telescope (JWST) is the identification of planets with the building blocks of life. The powerful infrared observation of the JWST allows it not only to find many planets outside of our own solar system, but to examine the atmospheric characteristics of those planets.
We have a thick atmosphere here on Earth that traps heat and water on our surface. Heat and water provide the only known conditions that allow for life to develop.
The James Webb can detect the signature of gases on a planet by how starlight waves appear when they pass through that planet's atmosphere. If the telescope finds evidence of double oxygen molecules called dimers, this will suggest both a thick atmosphere and the presence of liquid water. Wherever on Earth we have found liquid water, we have also found life. Therefore, the presence of liquid water on a planet is a strong indication that there will be life present on that planet.
It is truly an amazing consideration that in 2018 we will theoretically be able to detect habitable conditions on a planet considering that it was just 1992 when we discovered the very first known planet outside of our own solar system.
-Excerpted from "Looking Into the Infinite" by S. P. Ace Cadet
