I have no idea. I have never noticed anything like this myself, nor have I ever heard of it until now.
Lol, of course. I have no doubt that at least SOME water was around in the nebula that we were formed from.I think water was around long before the Earth, at least according to http://news.yahoo.com/black-hole-sucks-140-trillion-times-worlds-oceans-163503124.html" [Broken]
It seems the Universe is predisposed to create water whenever H2 and O2 meet, at least if they meet with the relatively slight amount of energy required for combustion.
Oh, I see now what you were getting at.Do you mean that the atoms that eventually formed all the water was in the nebula already, or that the actual water molecules were already formed? I'm guessing the former.
The technique, called laser-assisted water condensation, sees laser beams create water droplets in the air allowing mankind to, for the first time, determine where and when rain falls. This could solve drought, famine and all sorts of climate change catastrophes. Except storms.
“We have not yet generated raindrops – they are too small and too light to fall as rain. To get rain, we will need particles a hundred times the size, so they are heavy enough to fall,” said Jérôme Kasparian, a physicist at the University of Geneva, writing in the journal Nature Communications.

High speed photometer measurements show that the duration of sprites is only a few ms. Current evidence strongly suggests that sprites preferentially occur in decaying portions of thunderstorms and are correlated with large positive cloud-to-ground lightning strokes. The optical intensity of sprite clusters, estimated by comparison with tabulated stellar intensities, is comparable to a moderately bright auroral arc. The optical energy is roughly 10-50 kJ per event, with a corresponding optical power of 5-25 MW. Assuming that optical energy constitutes 1/1000 of the total for the event, the energy and power are on the order of 10-100 MJ and 5-50 GW, respectively.
The team, led by Jerome Kasparian, first tested the method in a lab setting. By shooting a 220-millijoule laser beam into a below-freezing, water-saturated chamber, scientists were able create clouds. To understand just how powerful that laser beam is, 220 millijoules is about as much energy as the intensity of 1,000 power plants!
Saturn’s moon, Titan, is unique in that it is the only moon in our solar system that has an atmosphere. That, in turn, has led scientists to ponder whether there could also be lightning on Titan. To date, no such phenomena has been detected in data collected by various space missions.
Alas, no such high-intensity electrical discharges have been directly observed by the electromagnetic sensors on board various spacecraft, including Europe’s Huygens spacecraft, the Voyager missions launched in the 1970s, and NASA’s Cassini spacecraft.
Venus is a hellish place of high temperatures and crushing air pressure. The European Space Agency's Venus Express mission adds into this mix the first confirmation that the Venusian atmosphere generates its own lightning. The discovery is part of the Venus Express science findings that appear in a special section of the Nov. 29 issue of the journal Nature.
the ratio of deuterium - or "heavy hydrogen" because it contains a neutron in addition to a proton - to hydrogen in our sea water matches the value found in water-rich asteroids, suggesting a common origin.
But Genda and his colleague Masahiro Ikoma suggest another possibility. They say the Earth could have had a thick atmosphere of hydrogen, which reacted with oxides in the Earth's mantle to produce copious water.
Also, chemical reactions favour the gradual exchange of hydrogen in water molecules for deuterium. Genda and Ikoma conclude from their calculations that that the oceans might well have been chemically manufactured right here on Earth.
"We saw the lightning," said Christopher Ruf of the University of Michigan in Ann Arbor, who first developed the new detector for use on Earth-orbiting weather satellites.
I mean it's probably nothing comparable to the Earth, however that's interesting...A strong electric field near the surface was discovered by the Kayuga (Selene) lunar orbiter, managed by the Japan Aerospace Exploration Agency (JAXA).
JAXA launched the Kaguya probe in 2007. The craft orbited at a mere 62 miles (100 kilometers) above the moon's surface for 20 months, returning the first high-definition movies of the lunar landscape.
Article says "first measurements" and is published in 2012 September, so perhaps this is new information to the science community?Atomic oxygen and atomic hydrogen have been inferred from the hydroxyl airglow measurements on Solar Mesosphere Explorer (SME) spacecraft between 0.01 and 0.0013 mbar (80–93 km). This constitutes the first measurements of the seasonal and latitudinal variations of these atomic species, in the mesopause region.
Night clouds or noctilucent clouds are tenuous cloud-like phenomena that are the "ragged-edge" of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in the upper atmosphere, visible in a deep twilight.
The last figures I saw on an estimation of the composition of Jupiter's atmosphere put the water content at 0.0004% but considering Jupiter's Mass that figure comes out to approximately 50% of Earths total mass.Earth may have the most visible water of all the planets, but there's no telling how much might be in the gas giants under their outer atmosphere. Even if Jupiter has a small fraction of a percent of water composing it, it could be MORE than all the water on the earth. However I really don't know, so don't take that as a fact..
