; but the dayside detection means we have new insight into the dynamics of the Venusian atmosphere, and the circulation patterns therein, say a team led by physicist Heinz-Wilhelm Hübers of the German Aerospace Center .
Venus is a world that scientists are itching to study in greater detail. It's similar to Earth in many ways; but utterly, hellishly different in others. Its mass and composition are like Earth's, but where Earth is lush, verdant, wet, and crawling with life, Venus is a death pit.
Those clouds drop acid rain on Venus, and the entire atmosphere rotates around the planet at a tremendous rate. Winds far below Venus's cloud tops can scream per hour. On Earth, the highest wind speed ever recorded was a hurricane gust of 407 kilometers flying high in Earth's own atmosphere, in the terahertz wavelength range that straddles microwave and far-infrared.
At all 17 locations, the team detected atomic oxygen, peaking in concentration at an altitude of about 100 kilometers . This corresponds to an altitude that sits directly between two dominant atmospheric circulation patterns on Venus: theThis means, the researchers say, that atomic oxygen represents a heretofore untapped resource to probe this atmospheric transitional zone on Venus.
"Future observations, especially near the antisolar and subsolar points but also at all solar zenith angles, will provide a more detailed picture of this peculiar region and support future space missions to Venus,"
