Sentences with phrase «venusian lightning»

Positive detections of radio wave emissions due to Venusian lightning have been reported (Ksanfomaliti et al. 1979; Taylor et al. 1979; Russell et al. 2007).

However, the lack of radio observations by the Cassini spacecraft during two close flybys and the lack of optical detections by Venus Express as well as ground - based observers leave the question of Venusian lightning somewhat unresolved (Yair et al. 2008; Yair 2012).

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.

Not exact matches

Venus Express has also detected water molecules escaping into space, found concrete evidence for lightning in the venusian atmosphere, and provided infrared glimpses of the hot surface.

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).

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.
