- 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.
NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission will study Venus from above its clouds down to its surface, investigating how the planet and its massive atmosphere formed and evolved over the past 4.5 billion years.
Oct 26, 2023 · Simulations produced by a Brown-led research team offer evidence that Venus once had plate tectonics — a finding that opens the door for the possibility of early life on the planet and insights into its history. Photo by NASA/JPL.
evolution of Venus is the dense and near-random distribution of 912 impact craters, and the small fraction of them that are modified, implying either a global resurfacing around 500 Ma, or an extremely localized tectonics.

Nov 9, 2017 · How did Venus become a sulfurous inferno, while Earth evolved to become the only known world with life? Although not currently habitable, Venus lies within the Sun’s "Goldilocks zone," and may have been habitable before Earth. Exploring the surface of Venus is difficult because of the intense heat and crushing air pressure. Read More
VERITAS, and another mission called DAVINCI, will be the first NASA spacecraft to explore Venus since the 1990s. Veritas will discover the secrets of a lost habitable world, gathering data to reveal how the paths of Venus and Earth diverged.
Jul 8, 2020 · To determine if Venus’ tessera plateaus formed in a similar way to Earth’s continents, VERITAS would construct the first global multispectral maps of Venus’ surface composition. If their composition resembles that of continental crust, we’d also gain information about Venus’ wetter past.
