And there's no doubt that it is absolutely wild to imagine that deep beneath your feet is a center of molten iron as hot as a star. But before you get too bowled over -- our Earth has a star inside! How is it that the sun's corona reaches such a high temperature, while its surface remains so much cooler? The answer is As Jay M. Pasachoff, an astronomer at Williams College, told Scientific American , the matter of why the sun's corona is so hot is "one of the important unsolved problems of astrophysics.
The moon is only about , miles away, so all your DNA would stretch to the moon and back alomst times. The sun is 93,, miles away, so your DNA would reach there and back about 4 times!
Interestingly, no more than 1. Read more. Naw that's foolishness. While a key doctrine of Christian and Muslim faith is that Jesus was conceived without help from Mary's husband, parthenogenesis has never been observed in mammals, and biblical accounts are widely disputed by religious scholars.
Nevertheless, there are at least eight other reported virgin births, and in June , it was revealed by the BBC that a British insurer, britishinsurance. The payout was to cover the costs of bringing up another Christ. On the other hand, the BBC announced yesterday that a Komodo dragon at the Chester, England zoo had laid fertilized eggs despite the absence of any male lizards. Parthenogenesis, you see, does occurs in some plants, invertebrates, vertebrates including reptiles, fish and, very rarely, birds.
Finally, we have the crust, which is the outer shell that we live on. The closer to the middle of the Earth, the higher the temperature; so the core is the hottest part, and it only gets colder as you move outward towards the crust. This heat is actually left over from when the Earth formed over 4 billion years ago!
It is leaving the Earth, but just taking a very long time to do so. The Sun is a bit more complicated.
It is still a mystery why the outside of the Sun can be hotter than the middle, but many scientists are working very hard to try to find the answer.
