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.
Neptune's atmosphere is made up of hydrogen, helium and methane. The methane in Neptune's upper atmosphere absorbs the red light from the sun but reflects the blue light from the sun back into space. This is why Neptune appear blue. Neptune's blue color is largely the result of absorption of red light by methane in the atmosphere but there are some additional as yet unidentified chromospheres which gives the clouds their rich blue tint.
