    • 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.
  1. Venus is similar in structure and size to Earth, and is sometimes called Earth's evil twin. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. Below the dense, persistent clouds, the surface has volcanoes and deformed mountains.

    • Contrary to its name, Venus is a hellish place. Venus is named after the Roman goddess of love and fertility, and before the space age, the perception of the planet was driven by science fiction.
    • Venus is still geologically active. The low number of craters on Venus indicates that geologic processes may be recycling aged landscapes into pockets of fresh ground.
    • Nasty clouds populate its crushing atmosphere. Venus has a dense atmosphere. When the Venera 4 probe descended through that gassy sheath in the mid-1960s, it measured the composition to be primarily carbon dioxide.
    • Venus twirls in a different direction. Almost all planets in our solar system, Earth included, spin counterclockwise on their axes. Venus is the only oddball that pirouettes clockwise.
