Volcanoes may have killed Venus with a runaway greenhouse: Implications for Earth-bound volcanism

What turned Venus into hell? It could have simply been a steadily warming sun, but new research suggests that volcanoes may have played a role in creating a runaway greenhouse effect. And the same history of active Volcanism ...

Why Venus rotates, slowly, despite sun's powerful grip: Planet's atmosphere explains the gravity of the situation

If not for the soupy, fast-moving atmosphere on Venus, Earth's sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon always faces Earth.
