Researchers from Astrobiology report that signs of life could be possible using a tool that measures atmospheric pressure when viewing two oxygen molecules or dimers. By doing so, using a telescope such as the James Webb Space Telescope, scientist will be able locate detectable signs of oxygenated atmospheres that are sufficient enough to sustain life. According to Science Mag, “When a planet passes in front of its star, starlight shines through the planet’s atmosphere and continues through space until it reaches us. Dimers in the atmosphere absorb light like a color filter on a camera lens..”. The James Webb Telescope is said to launch 2018.
