Venus: Earth's Not-So-Twin Planet

SHAH

Venus, our closest planetary neighbor, has often been called Earth's twin due to its similar size and mass. But beneath the thick veil of clouds that shroud the planet lies a world far stranger and more hostile than anything found on Earth.

Venus is the hottest planet in our solar system, with surface temperatures hot enough to melt lead. This scorching heat is caused by a runaway greenhouse effect. The atmosphere of Venus is crushing, 96% carbon dioxide, trapping heat from the sun much like a blanket.

Despite the scorching temperatures, Venus was once thought to be a potentially habitable world.  The thick atmosphere hinted at a warm, wet planet.  However, missions sent to explore Venus revealed a different story. The surface is a desolate landscape of volcanoes and plains, ravaged by the extreme heat and pressure.

Here are some of the weird and wonderful features of Venus:

Rotates Backwards: Unlike most planets, Venus spins in the opposite direction of its orbit around the Sun. This means the sun would rise in the west and set in the east on Venus!

Volcanic Activity: Venus is rife with volcanic activity. The thick atmosphere is choked with volcanic gases and dust, sculpting the Venusian landscape.

Supercritical Carbon Dioxide: The pressure at the surface of Venus is so immense that carbon dioxide doesn't behave like a gas, but rather a supercritical fluid, similar to water at high temperatures and pressures.

Despite the harsh conditions, Venus continues to be a target for exploration.  Scientists are particularly interested in the possibility of past oceans or even microbial life existing in the cooler upper atmosphere.

So next time you gaze up at the night sky and see the brilliant light of Venus, remember, it's a world of mystery, a scorching testament to the diversity of our solar system.
