Oxygen represents about 21% of Earth's air, with the rest of our air consisting mainly of nitrogen. What's more, most living things - including people, as we certainly understand them - need oxygen.
Earth's neighbor Venus offers a seriously unique story. Its dense and noxious atmosphere is dominated by carbon dioxide – 96.5 percent – with a low measure of nitrogen and gases to follow. Oxygen is almost absent. Indeed, with Venus standing out from other planets, for example, Mars, the immediate location of its oxygen remains problematic.

Using an instrument on board the Sofia airborne observatory – a Boeing 747SP aircraft modified to carry an infrared telescope in a joint venture between NASA and the German Aviation Space – researchers have now identified atomic oxygen in a tiny layer sandwiched between two different layers of Venus. air
They noted that this atomic oxygen, which consists of a solitary oxygen iota, contrasts with subatomic oxygen, which consists of two oxygen particles and is respirable.
The scientists made the striking distinction in favor of Venus by pointing the oxygen directly toward the Sun—where it really formed in the atmosphere—as well as identifying it as an afterthought away from the Sun, where it was recently seen by a ground-based telescope. Hawaii Venus pivots more leisurely than Earth.
"The atmosphere of Venus is very thick. The creation is likewise completely different from Earth," said German aviation place physicist Heinz-Wilhelm Hubers, lead author of the review distributed in the diary Nature Correspondence.
The thick atmosphere of the second planet from the Sun traps heat in an out-of-control nursery effect.
"Venus is inhospitable, basically to the creatures we know from Earth," Hübers added.
Oxygen is created by the sun's radiant radiation, which dissociates barometric carbon dioxide and carbon monoxide into oxygen molecules and various synthetic substances, the scientists said. A portion of the oxygen is transported through the atmosphere to the Venusian night.
"This position of atomic oxygen on Venus is immediate verification for the activity of photochemistry - set by the sun's ultraviolet radiation - and for the carriage of its material in the Venusian atmosphere," said astrophysicist and study co-author Helmut Wiesemeyer of the Maximum Planck Foundation for Radio Stargazing in Germany.
"On the planet, our life-sustaining stratospheric ozone layer addresses a significant picture of such photochemistry," Wiesemeyer added.
