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.
The atmosphere of Neptune is 74 percent hydrogen, 25 percent helium and one percent methane. Its atmosphere is full of fearsome storms. Other than the Great Dark Spot, Neptune has other named areas of storms like the Scooter and the Small Dark Spot.
