What did radio astronomy show us about venus? Venus’ clouds are no obstacle to radio waves — the long wavelengths of light pass through them. Radio astronomers announced that Venus had surface temperatures well above the boiling point of water! No jungle could survive in such a planet-sized oven, and descriptions of a harsh, desert planet soon arose.
Why do we need radio waves to study the surface of Venus? Venus’s surface is covered by toxic acid rain clouds, making it hard to study. Additionally, its surface temperature is more than 860 degrees Fahrenheit, making landing spacecraft an impossibility. A low-frequency radio signal may offer clues. Theoretically, Venus shouldn’t be too dissimilar to Earth.
What can we learn from radio astronomy? Radio telescopes look toward the heavens to view planets, comets, giant clouds of gas and dust, stars, and galaxies. By studying the radio waves originating from these sources, astronomers can learn about their composition, structure, and motion.
Are there any important discoveries on Venus? It found volcanoes, long lava channels, pancake-shaped domes, and evidence of hot mantle plumes at depth (like the one responsible for creating the Hawaiian islands). More recently, ESA’s Venus Express orbited from 2006 to 2014. Japan’s Akatsuki Venus Climate Orbiter has been orbiting Venus since 2016.
