The weather on Earth can be pretty destructive, but aside from the occasional fire tornado, it’s mostly just water falling out of the sky. If you want really crazy weather, you need to get off this planet. The stuff going on around other planets and stars makes hurricanes seem like a soft summer breeze.
The surface temperature is 980 degrees Celsius (1,800 °F), and it has winds of 6,400 kilometers (4,000 mi) per hour. The extreme temperatures mean that its atmosphere is evaporating, causing the planet to lose up to 600 million kilograms (1.3 billion lb) every second.
Though the planet is relatively close in galactic terms, we needed a clever trick to figure out its hellish weather. Scientists used the Hubble to pick up light while the planet was beside the star, then again when it had moved behind.
