About 21% of Earth's atmosphere is made up of oxygen, with the rest primarily nitrogen. As we know, most living organisms, including humans, need oxygen to survive. However, the planet Venus, Earth's neighbor, has a completely different story. The dense and toxic atmosphere of Venus consists of 96.5% carbon dioxide and smaller amounts of nitrogen and trace gases. There is almost no oxygen on this planet. In fact, since Venus has received less scientific attention compared to other planets like Mars, the direct detection of oxygen in its atmosphere has remained challenging. According to Reuters, in a new study, scientists have used an instrument from the Stratospheric Observatory for Infrared Astronomy, known as SOFIA, to identify atomic oxygen in a thin layer located between two other layers of Venus's atmosphere. The Stratospheric Observatory for Infrared Astronomy is an airborne observatory mounted on a Boeing 747SP aircraft, belonging to the German Aerospace Center and the National Aeronautics and Space Administration (NASA). Researchers in this study noted that this atomic oxygen, which consists of a single oxygen atom, differs from molecular oxygen, which is made up of two oxygen atoms and is breathable. They identified the presence of oxygen directly for the first time on the sunlit side of Venus, as well as on the side facing away from the sun, which had previously been observed by a ground-based telescope in Hawaii. Venus rotates much slower than Earth. Heintz-Wilhelm Hubers, a physicist at the German Aerospace Center and the lead author of the study, stated, "The atmosphere of Venus is very dense, and its composition is very different from that of Earth." The thick atmosphere of Venus, the second planet closest to the sun, traps heat in a process known as the "greenhouse effect." This condition, according to Mr. Hubers, is not habitable; "at least for the organisms we know on Earth." The results of this study were published this week in Nature Communications, an online peer-reviewed open-access scientific journal.
New Research: Scientists Discover Oxygen in the Atmosphere of Venus
Scientists have discovered atomic oxygen in the atmosphere of Venus using the SOFIA observatory, marking the first direct detection of oxygen on the planet. This finding is significant as it contrasts with Venus's toxic atmosphere, which is primarily composed of carbon dioxide. The research contributes to our understanding of planetary atmospheres and the potential for life beyond Earth.
