Astronomers at "McGill University" in 'Canada' have created a fingerprint of the earth's atmosphere, which is intended to detect planets suited to humans living in outer space. This atmospheric fingerprint has been created using data collected after observation of the Earth's atmosphere by the 'SCISAT' satellite for more than a decade. Through the 'SCISAT' satellite, astronomers can estimate the gases present in the atmosphere by observing changes in the brightness of the sun's rays in the atmosphere. After this study, the presence of carbon dioxide, oxygen, and water vapor in the atmosphere of a planet can be explored through the telescope.
