An ice cube, for example, pours out a larger fraction of its light at longer infrared wavelengths than a cup of hot tea emits. No data is shared with Facebook unless you engage with this feature. I hope that in the not to distant future, we will have technology in place to destroy or at least change the orbit of dangerous comet or asteroids so that it does not strike the Earth. It's a goose-bump moment when you watch a little seed grow into a plant, then think of all the vast universe full of life. Outer space is fascinating, especially when you consider its age and size.
