Oxygen was found to be concentrated at an altitude of about 60 miles (100 km) between those two crustal layers. Oxygen temperatures on the planet ranged from minus 184 degrees Fahrenheit (minus 120 degrees Celsius) during the day to minus 256 degrees Fahrenheit (minus 160 degrees Celsius) at night.
Methods previously used to detect daytime Venusian oxygen were indirect, based on measurements of other molecules in combination with photochemical models.
Venus, about 7,500 miles (12,000 km) in diameter, is slightly smaller than Earth. In our Solar System, Earth lies comfortably within the “habitable zone” around the Sun – a distance considered neither too close nor too far from a star capable of hosting life, with Venus near the inner boundary. And Mars is close to the outer limit. Edge.
“We are still at the beginning of understanding the evolution of Venus and why it is so different from Earth,” Hubers said.
