A convection oven uses a powerful fan to circulate hot air, so any food -- roasts, bread and even delicate items like eggs -- cook about 15 percent faster. Classic baked eggs, or oeufs de cocotte, cook to an ethereal consistency in about 6 minutes in a convection, about 4 minutes faster than in a conventional oven.
We can't see a lot of features in Neptune's atmosphere, but the features that astronomers can detect appear to come and go in a hurry. When the Voyager 2 spacecraft flew past Neptune in August 1989, for example, it discovered the Great Dark Spot -- a dark, oval-shaped storm system as big as Earth.
Like Uranus, Neptune appears blue due to the methane in its atmosphere, but Neptune also has vivid blue clouds; it is not known what gives the clouds their color. Like all the other gas giants, Neptune has rings. Prior to images from Voyager 2, these rings were only visible from Earth as faint, dark arcs.
