We explored the recesses of our solar system, our telescopes scan the galaxy in search of earth-like planets but we still know so little about our closest neighbor, Venus. Maybe because is easier to gather informations about inert planets rather than active ones. And Venus is still more than active. It will not be easy to penetrate its scorching atmosphere but I'm confident that one day all the misteries will be unvealed.
Sulfur behavior in Venus atmosphere explained
The beautiful dark stripes on ultraviolet images of Venus's disc are in no way connected with the crystalline sulfur particles in its atmosphere -- the ultraviolet is absorbed by another substance. This has been proven by data obtained from the first ever model of the distribution of sulfur in Venus's gaseous envelope. Ref. Source 7w.
Venus may have been habitable, NASA climate modeling suggests
Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to two billion years of its early history, according to NASA computer modeling of the planet's ancient climate. Ref. Source 8n.
