More Electric Comet Evidence

[flyingcloud]

couldn't find the electric comet thread I was going to add to it...

anyway I wonder what this article would read like if they eliminated all that magnetic, electric, ions, and plasma mumbo jumbo that doesn't really convince anyone in the scientific community that comets are electrical entities by nature

they are not measuring the comet's size but the comet's charge differential... duh


Biggest Comet Measured to Date: Comet McNaught

http://www.sciencedaily.com/releases/20 ... 124424.htm

ScienceDaily (Apr. 14, 2010) — British scientists have identified a new candidate for the biggest comet measured to date. Dr Geraint Jones of UCL's Mullard Space Science Laboratory presented the results at the RAS National Astronomy Meeting in Glasgow on April 13. Instead of using the length of the tail to measure the scale of the comet, the group used data from the ESA/NASA Ulysses spacecraft to gauge the size of the region of space disturbed by the comet's presence.

Analysis of magnetometer data shows evidence of a shockwave surrounding the comet created when ionized gas emitted from the comet's nucleus interacts with fast-flowing particles in the solar wind, causing the wind to slow down abruptly.

In January and February 2007, Comet C/2006 P1 McNaught became the brightest comet visible from Earth for 40 years. Serendipitously, Ulysses made an unexpected crossing of Comet McNaught's tail during this time, one of three unplanned encounters with comet tails during the 19-year mission. The other encounters included Comet Hyakutake in 1996, the current record-holder for the comet with the longest tail.

Ulysses encountered McNaught's tail of ionized gas at a distance downstream of the comet's nucleus more than 1.5 times the distance between the Earth and the Sun. This is far beyond the spectacular dust tail that was visible from Earth in 2007.

Dr Jones said, "It's very difficult to observe Comet McNaught's plasma tail in comparison with the dust tail, so we can't really estimate how long it might be. What we can say is that Ulysses took just 2.5 days to traverse the shocked solar wind surrounding Comet Hyakutake, compared to an incredible 18 days in shocked wind surrounding Comet McNaught. This shows that the comet was not only spectacular from the ground; it was a truly immense obstacle to the solar wind."

A comparison with crossing times for other comet encounters demonstrates the huge scale of Comet McNaught. The Giotto spacecraft's encounter with Comet Grigg-Skjellerup in 1992 took less than half an hour from one shock crossing to another; to cross the shocked region at Comet Halley took a few hours.

"The scale of an active comet depends on the level of outgassing rather than the size of the nucleus," Dr Jones added. "Comet nuclei aren't necessarily active over their entire surfaces, and all we can say is that McNaught's level of gas production was higher than that of Hyakutake."

Candidate shock features had been found in Ulysses magnetometer data from the Hyakutake encounter in 1996 but their identification was tentative, especially so far downstream from the comet's head. The discovery of similar features at McNaught suggests that this interpretation is correct.

nothing sadder than when a solar wind is shocked...

"Dr jones, Dr jones.... calling Dr jones... Dr Jones, Dr Jones wake up now"

"please please cure me, please please cure me"

This is soo stoopid, it's time for a laugh... click on the above video and picture Dr Jones realizing the ELECTRIC COMET

once again everyone in the scientific community was surprised by the recent findings illustrating the electrical nature of cometary bodies that even the solar wind was shocked

I'm not sure if the article confirms so much and the scientists don't seem that surprised (as they're at least mentioning plasma tail and interactions). By coincidence I came over this older article (same website and subject), and it seems to have more technical data and surprisingly much confirmation of the electrical nature of comets.

http://www.sciencedaily.com/releases/20 ... 165932.htm

For the first time at a comet, researchers detected O3+ oxygen ions (atoms of oxygen with a positive charge because they have five electrons instead of eight). This suggests that the solar wind ions, originally missing most of their electrons, picked up some of their missing electrons when they passed through McNaught's atmosphere. The comet served as a source of electrons, said Michael Combi, a U-M space science professor who is an author of the paper.

As I mentioned in a previous comet post, the photoelectric effect causes the comet nucleus to emit electrons to an escalating degree as it approaches the Sun.

"This was very surprising to me," Combi said. "Way past the orbit of Mars, the solar wind felt the disturbance of this little comet. It will be a serious challenge for us theoreticians and computer modelers to figure out the physics."

We could grin, but there is some integrity in partly admitting that they're been wrong and the interpretation of data is sincerely mentioning electrical terms. (They are of course wondering off talking about the origin of the solar system and so forth as well...)

From the above article:

"The benefits of such an observation are important," he said. "They constrain the interactions of such comets with the sun, including how the comets lose mass. They also examine the question of how a sudden injection of neutral and cold material interacts with hot solar-like plasmas. That occurs in other places of the universe and we were able to study it right here."

Wow... I wonder if they recognize to which extent these interactions happen in the Universe. And if they withhold the electrical processes they've briefly mentioned in regards to this comet.

great article siggy, thanks
