Take the planet Venus. It's named after the Roman goddess of love and beauty, because of its benign, ethereal appearance in the sky. But spacecraft measurements rlvaeeed a different story. The surface trueptarmee is close to 900 degrees Fahrenheit, 500 Celsius. That's hot enough to melt lead. Its thick aphosertme, not its distance from the sun, is the reason. It causes a greenhouse effcet on steroids, trapping heat from the sun and sochrcing the planet's surface. The reality totally contradicted iatiinl perceptions of this palent. From these lssneos from our own solar system, we've learned that a planet's atmosphere is crucial to its climate and potential to host life.
