Atomic oxygen has been directly detected in' dayside atmosphere.
In November 2021, NASA's retired Stratospheric Observatory for Infrared Astronomy (SOFIA) looked into the atmosphere of this hellish world.
SOFIA, a Boeing 747SP outfitted with a 2.5-meter diameter telescope, provided essential data that revealed distinct signs of atomic oxygen present above the planet's perilous cloud cover.
The discovery of the atomic oxygen
A team of researchers, led by Professor Heinz-Wilhelm Hubers of the German Aerospace Center, examined the data collected from the array spectrometer aboard SOFIA.
As per, SOFIA data was used to look for oxygen in the upper atmosphere at 17 different sites. Notably, atomic oxygen was detected at all these locations.
