   • Did Venus ever host life? Big questions are often asked when thinking about other planets: Is there life? WAS there ever life? If so, what sort of life?
   • How did Venus and Earth come to be so different? Venus and Earth are similar in size and density, so hypothetically, these planets could be very similar.
   • How did Venus form? Even this seemingly basic question about the origin of Venus is still a mystery. “It’s amazing to me that we don’t know whether Venus formed from the same early solar system materials as did Earth and Mars,” says Getty.
   • What is the atmospheric composition at Venus? The atmospheric composition of Venus is an important piece of the context we are seeking as we aim to better evaluate Venus’ potential habitability over time.

   What really happened to Venus?

   • Venus’s overabundance of heavy water is thought to be the dregs from an ocean’s worth of normal water that graced the planet eons ago. To learn what really happened to Venus, we need to find out what happened to all that water. The planet, Garvin says, should not be thought of as a hellish pandemonium but “as an ocean world that lost its oceans.”

   Is Venus a mystery?

   • That was NASA’s most recent mission to Earth’s sister planet, and while we have gained significant knowledge of Venus since then, there are still numerous mysteries about the planet that remain unsolved. NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission hopes to change that.

   Why is Venus so inhospitable?

   • Venus is particularly inhospitable: It is 100 times hotter than Earth with an atmosphere so thick that the longest any spacecraft has survived on its surface before being crushed is a little over two hours. Perhaps such vulnerabilities to the sun’s storms contributed to this environment.
