Venus' Once Molten Surface

If you had radar eyes, you might see Venus like this. This computer reconstruction uses data from the Magellan spacecraft, which mapped Venus's surface with radar from 1990 to 1994. Magellan found many intriguing features, including large circular domes, typically 25 kilometers across, shown here. These domes are thought to be volcanic in origin, though the exact formation mechanism is still being studied.
