In 2004, Schulze - Makuch and his colleagues announced their speculations that such microbes may survive in Venusian clouds with the help of molecular rings of sulphur to shelter from the Sun's ultraviolet (UV) radiation as Venus does not have a protective layer of ozone in its atmosphere.

Dr. Sakanoi specializes in determining the variations in planetary atmospheres, such as Jovian aurora and Venusian clouds by obtaining continuous monitoring data with the T60 and T40 telescopes at Haleakala summit.

While the exact mechanism for charging and for initiating lightning within the Venusian clouds is not currently known (Yair 2012) it is nonetheless likely that cosmic ray ionization has an important role in this process as it is believed to be the primary source of atmospheric ions at middle and low altitudes.

To see what lay beneath the Venusian clouds, astronomers at Arecibo sent radar signals to Venus.

The simulated image at left shows how the smaller particle size in Venusian cloud tops (compared to a typical 10 to 40 micrometers in terrestrial ones) causes the colored fringes to spread further apart than they would appear on Earth.

While the large atmospheric pressure at the surface and the high altitude of the Venusian cloud layer appears to exclude the possibility of cloud - to - ground lightning (Gurnett et al. 2001; Aplin 2006), several authors have suggested that lightning discharges above, between or within clouds may occur (Borucki 1982; Russell & Scarf 1990; Gurnett et al. 2001).

Regarding the search for extraterrestrial life, the one major habitable zone in the inner solar system that has not been sampled at all is the Venusian cloud layer, which in terms of temperature, pressure and gravity is the most Earthlike extraterrestrial environment in the solar system.

However, a new study of the atmosphere suggests that clouds may have kept the planet cool enough to preserve the Venusian sea for billions of years — far longer than previously thought.

In visible light Venus appears covered in a featureless white cloud layer, but a camera onboard Mariner 10 captured these cloud details in the ultraviolet range, which provided clues about the structure of the Venusian atmosphere.

Toward the end of that year, though, the Pioneer Venus probe entered Venusian orbit — and immediately recorded suspiciously high levels of sulfur dioxide above the clouds.

Dubbed the first planetary meteorological satellite by mission scientists, Akatsuki was supposed to orbit Venus for 2 years, using its five cameras operating at ultraviolet and infrared wavelengths to track clouds at different altitudes and watch for venusian lightning.

The oceans will boil away and the atmosphere will dry out as water vapor leaks into space, and temperatures will soar past 700 degrees Fahrenheit, all of which will transform our planet into a Venusian hell - scape choked with thick clouds of sulfur and carbon dioxide.
