Where Has All The (Venus) Water Gone? Long Time Passing...

The water in Venus' atmosphere is gone with the wind, new detections suggest.
This absence is strange, because astronomers think Venus and Earth likely began with similar amounts of water since they are about the same size and formed at the same time (some 4.5 billion years ago). Yet today, Earth's atmosphere and oceans contain 100,000 times the total amount of water on Venus.
Due to a greenhouse effect on Venus, temperatures at the surface can soar to about 870 degrees Fahrenheit (465 degrees Celsius). And so the water from the planet's surface immediately boils off. But its atmosphere is also relatively dry, and the question has been: where did that initial atmospheric water go?
