While some scientists do believe that Venus might have had oceans in the past, a new study disagrees. A team of scientists announced on October 13, 2021, that their computer models show that Venus lacked oceans from the beginning.
The peer-reviewed journal Nature published this study on October 13. The scientists, from the University of Geneva and French National Centre for Scientific Research, used a state-of-the-art climate model to reach their conclusions.
These scientists’ work indicates that conditions were never right for rain to fall on Venus, and so for oceans to form.
Venus itself formed 4.5 billion years ago along with the sun, Earth and the rest of our solar system. Like the young Earth, the young Venus was likely covered with magma, or molten rock.
