Most people think of the empty space between the stars as being, well, empty. But it is not. It is actually filled with gas. Admittedly, at an average density of 100-1,000 molecules per cubic centimetre (compared with 100 billion billion in air at sea level), it is a pretty thin gas. But space is big, so altogether there is quite a lot of it. Most of it, about 92%, is hydrogen. A further 8% is helium, which is chemically inert. But a tiny fraction--less than one-tenth of a percent--consists of molecules with other elements, such as oxygen, carbon and nitrogen, in them. Though these other elements are a mere soupcon of the interstellar soup, they do give it real flavour. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
