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 Earth, Neptune has a rocky core made up of iron and other metals, with a mass just greater than our planet. Temperatures in the core could reach 9,260 F (5,127 C). Strange rings. Like the other gas giants, Neptune boasts a series of rings. But the blue planet's six rings are not as solid as its neighbors. Instead, the clumpy rings contain prominent arcs, likely due to the influence of one of Neptune's moons. Made up of ice particles and silicates, the rings are reddish. Neptune's rings were first discovered when it passed between a star while astronomers were attempting to study the planet. The star faded out, then returned to view.
