Growing Cosmic Snowflakes

3) Do snowflakes form in Earth orbit from the solar wind (hydrogen) and upper atmospheric oxygen (O+ ions). The very upper atmosphere is atomic oxygen, not ionic oxygen, but, no, ice isn't going to form there. The pressure is far too low and the temperature far too high. The highest point in the atmosphere where ice could be stable is in the mesosphere (see: noctilucent clouds). Paul |

True, but I was wonder about a little further out, and where in the magnetosphere would be a likely place for Snowflakes to form. Earth, has all the making for a Cosmic Snowflakes, O2, O, O+, H or protons. The list of unique properties of water is getting quite long http://www.lsbu.ac.uk/water/explan.html One of these unique properties is that water can form ions, H2O+, H2O-, and neutral H2O. Ionic bonding of atoms are some of the strongest bonds that can form. So, water should be able to self nucleate. H2O+ + H2O- = bonded 2H2O http://massey.dur.ac.uk/drf/protoste...mistry_species -- Craig Fink Courtesy E-Mail Welcome @ |

Any snowflake in space near the Earth will be heated by sunlight, and will have a vapor pressure far higher than the ambient pressure, and will disappear in short order. (Liquid water released into space will partially boil and partially freeze, and the 'snow' from the latter will persist for a while, but will evaporate before too long.) Paul |

Hummm, I would have really tried hard to leave out the nonsensical
deragatory comments. And, added that in the shadow of the Earth might be the best, coolest, least vapor pressures... And, tried to supply some url for everyone who... http://www.lsbu.ac.uk/water/explan.html Items 1,2,...there are some others that are applicable. http://www.lsbu.ac.uk/water/phase.html Below 200K would be a nice place. http://massey.dur.ac.uk/drf/protoste...mistry_species Items 12, 41 and 61 Wow, this is an interesting question. Where within Earth's Magnetosphere would Snowflakes form? Would it possibly look like a big fountain? -- Craig Fink Courtesy E-Mail Welcome @ |

Here is a good read on the Magnetosphere, aurora, ... http://meted.ucar.edu/hao/aurora/txt/x_menu.php Since it's been a long time since I've read anything on the subject, I've been trying to relieve my own ignorance on the it. It's really interesting how computers and animated diagrams can improve one's understanding of a fairly difficult subject. The neutral sheet in the magnetosphere http://en.wikipedia.org/wiki/Image:M..._schematic.jpg and Earth's shadow looks like the most likely place for Snow formation. Second animation down is interesting. http://meted.ucar.edu/hao/aurora/txt/x_a_2_0.php The fountain part, neutral sheet, earth's shadow, magnetotail 20-25 Earth radii extending past 200 radii with the moon orbiting past at 60 radii. Maybe a big sputtering fountain of Cosmic Snowflakes? -- Craig Fink Courtesy E-Mail Welcome @ |
