What kind of 'snow' falls on the highest peaks of the planet Venus?

The short version
  • Snowflakes of lead and bismuth drift down on Venus. Seriously!
  • From a distance, these mountains look just like the snow-capped Alps.
  • If you stood on the summit, the air would be a thick, soupy carbon dioxide haze, and the ground would be a shimmering, toxic sheet of industrial-gr…

Snow on Venus would melt your face off before it hit the ground. On the highest mountain peaks of our sister planet, the mountains are frosted with metal.

Venus is hot enough to melt lead at its surface. This heat vaporizes metals like galena and bismuthinite, turning them into a metallic mist that rises into the atmosphere.

As this mist reaches the cooler mountain tops-which are still over 800 degrees Fahrenheit-the metal condenses. Vaporized lead and bismuth condense directly onto the cold mountain surfaces. It settles onto the rocks as a shiny, reflective frost.

From a distance, these mountains look just like the snow-capped Alps. But instead of frozen water, the peaks of Maxwell Montes are plated in lead and sulfur.

This metallic coating is why Venusian mountains are so incredibly bright on radar maps. Spacecraft signal bounces off the metal like a mirror.

If you stood on the summit, the air would be a thick, soupy carbon dioxide haze, and the ground would be a shimmering, toxic sheet of industrial-grade ore.

How did this hit you?

Or say it in words - one line is enough.
