 Named After:

[Angela Gabriel] Named after the ancient Roman goddess of beauty, Venus is known for its exceptional brightness in the night sky. But behind this facade is a world of storms and infernos unlike anywhere else in the solar system.

Similarities with Earth

Venus, the second planet from the sun, is very similar to Earth from a distance. But up close, it's a very different world. Venus is about the same size as Earth, just slightly smaller.

Structure of Venus

Venus structure is also nearly identical, with an iron core, a hot mantle, and a rocky crust.

Crust of Venus

Venus's crust is dotted with thousands of volcanoes, including Maxwell Montes volcano almost as tall as Mount Everest. 

Atmosphere at Venus

Venus also has a thick layered atmosphere. It’s full of clouds that rain (thunder cracking) sulfuric acid, and whip around the planet at speeds up to 224 miles per hour. Faster than some category five hurricanes.

Atmospheric pressure

The atmosphere on Venus is so thick that it creates a surface pressure similar to what it would be about half a mile deep in the Earth's oceans. This pressure is heavy enough that a human standing on Venus' surface, would be crushed. The atmosphere is made of greenhouse gases, primarily carbon dioxide. That creates an extreme case of global warming. They trap the sun's heat, causing surface temperatures to rise over 880 degrees Fahrenheit. Makes Venus the hottest planet in the solar system.

Inhospitable

 Venus is so inhospitable, that neither humans nor spacecraft are able to survive the planet's surface. But some scientists speculate that Venus wasn't always so unwelcoming. 

From roughly 2.9 billion to 715 million years ago, global temperatures on Venus may have been just a few degrees cooler than Earth's are today.

Theories:

Scientists theorize that the surface may have contained shallow oceans that could have held enough water to support life. Today, life may still exist in Venus' atmosphere. About 30 miles up in Venus' clouds, where the temperature and surface pressure are similar to those on the surface of Earth, scientists have observed strange dark streaks that appear to be absorbing ultraviolet radiation.

Evidence of microbial life

A phenomenon that could be evidence of microbial life. Life may struggle to survive in the atmosphere of Venus, but it is this unforgiving environment that's made Venus an icon of beauty. It reflects 70% of all the sunlight that reaches the planet, which is why Venus shines more brightly than any other planet or star in the night sky. While more than 40 unmanned spacecraft have visited this infernal world, Venus, so illuminated in the darkness of space, still has much to reveal.
