Hubble telescope spots azure blue planet where it rains glass

This illustration shows a deep azure planet that astronomers found orbiting a star 63 light years away. STORY HIGHLIGHTS It is the first time astronomers have determined the color of an exoplanet The planet is 63 light years away Temperatures reach as high as 2,000 degrees Fahrenheit It possibly rains glass sideways in 4,500-mph winds Astronomers have found a deep azure blue planet orbiting a star 63 light years away -- the first time they've been able to determine the actual color of a planet outside our solar system, NASA and the European Space Agency said Thursday. The planet, known as HD 189733b, is a gas giant with a daytime temperature of 2,000 degrees Fahrenheit where it possibly rains liquid glass sideways amid 4,500 mph winds, NASA says. The blue color comes not from the reflection of an ocean, as on Earth, "but rather a hazy, blow-torched atmosphere containing high clouds laced with silicate particles," NASA says. "Silicates conde...

Physics behind the Arc Reactor

It started with me ranting about how I should understand the physics of arc reactor more and then Sera needs some babel speak ideas for her Tony. I know this has been discussed deeply by most iron man fanatics before, but this is the simplified version for people who can’t be bothered to understand the big science-y words. I’m not saying that this is accurate because I’m not a nuclear engineer either, and I hope I can get some feedbacks from people who actually understand this. Since vibranium is not actually a real element, I’m focusing on the old arc reactor tech that runs on palladium. Let’s do a bit revision on fusion, yes? During nuclear fusion, light atoms combine to form heavier elements; in the process, a small fraction of mass is converted into lots of energy. Fusion reactions are called thermonuclear reactions because high temperatures are required to overcome the coloumbic repulsion between the nuclei being fused, i.e., “thermo” for the heat required...
