The second planet from the sun, Venus, with its toxic overheated surface, has long been neglected by planetary mission planners. Lately, Earth's sister planet has taken center stage in one of the greatest quests in science today: the search for life-bearing worlds beyond the solar system. Scientists want to know: Why did Earth live, and why did Venus die?

Scientists puzzling out secrets of Venus' 30-year-old 'Giant Dark Cloud'

There are many strange things happening on Venus. Among them is a recognizable weather pattern that scientists now realize has persisted in the planet's atmosphere for at least 30 years.

Nicknamed the "Giant Dark Cloud," scientists first noticed that feature in data gathered by an infrared camera aboard the Japanese spacecraft Akatsuki, which has been orbiting Venus since 2015. The cloud is huge, spanning a third of the planet's latitude around its equator. After identifying the feature, scientists went looking for it in archives of similar infrared observations of the planet and found its signature across the full three decades' worth of relevant data..............

The Giant Dark Cloud feature has two aspects to it, McGouldrick noted. "Initially, this was called a 'disruption.' It was recognized as a sharp transition from light to dark that was fairly repeatable," he said. That transition unfolded over only a couple of degrees of longitude, although it stretches from the equator about 30 degrees latitude north and south. "But then there also was this massive structure behind it, almost hemisphere-size scale" — hence the name.

The whole thing also seemed to orbit differently from the rest of Venus' weather, lopping the planet once every five days, a few days more rapidly than what McGouldrick called "background clouds."..........
