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.
Many of these can't be seen from the Earth with the Hubble Space Telescope, but large changes in the atmosphere of Neptune are visible. As with Uranus, the color of Neptune is due to methane in its atmosphere, even though the main components of the atmosphere are hydrogen and helium. As mentioned previously, it appears that the internal structure is much like that of Uranus, and the magnetic field is also like that of Uranus (tilted 47 degrees from the rotation axis and off center).
