Deep Impact Comet Temple 1 Update
Happy St. Patrick's Day.
Happy Birthday Dennis :P
It is coincidence or quantum synchronicity that there are a multitude of green holidays during this month? Methinks not. :D
I watched "Fiddler on the Roof" last night. Hadn't seen the film for years and years. Released 1971. That's 35 years ago. I was 21. I cried through the whole movie. It brought to light situations and emotions that have since been forgotten. That's why we have to be constantly reminded not to forget, and even when constantly reminded we still forget. It was a film that depicted the history of my Tradition, and where it was that my people came from. I forgot. Fascinating and moving. I had forgotten the real plot of the movie and just remembered the songs, because after that film the songs became traditional Jewish Wedding songs. Fascinating. Actually, the film is about the change. the changing of the traditions. It really moved me. To tears. Weeping tears. Weeping is different than crying. Weeping. When the tears come out of the outer corner of your eyes and roll down your cheeks and drip off your chin. Weeping.

Deep Impact Comet Temple 1 Update

Ice layers record comet creation
By Paul Rincon BBC News science reporter, in Houston, Texas
Comets hold materials unchanged since the Solar System's formation
The Deep Impact mission is casting new light on how comets formed and how they shed their ice in space.
The US space agency probe sent a 370kg projectile crashing into Comet Tempel 1 and then studied the plume of debris with its suite of instruments.
Nasa's mission scientists say images from last July's encounter reveal as many as seven different layers on the comet's surface.
Their results were presented at a major science conference in Houston, US.
Team member Mike Belton told the meeting he thought the layering was a sign of how comets like Tempel 1 were built up from lesser objects.
Growing 'snowball'
In the outer part of the early Solar System, smaller bodies called cometesimals collided and merged, gradually piling up to form the larger objects we know as comets.
Similar collisions in the inner Solar System led to a loose accumulation of fragments that largely retained their internal structure.
But primordial material in the outer regions was travelling at relatively lower speeds and contained less solid material.
As the cometesimals hit the surface of a growing comet nucleus, they "flowed" on to the surface, researchers believe.
Deep Impact's scientists think the interior structure of Tempel 1 resembles layers of material piled up on one another - a signature of the process that formed the icy body.
Model conflict
Data from the mission is also helping scientists understand how comets shed water-ice through sublimation, the phenomenon which sees a solid become a gas without first melting.
When comets are heated by the Sun, ice sublimes and is lost to space in a process known as outgassing. Some scientists have proposed that this material is coming from deep below the surface crust of the comet.
But temperature data from Tempel 1's nucleus suggests the material must be lost from only a few centimetres below the surface.
"The normal outgassing of the comet has been modelled by different people as coming from bare ice on the surface to subsurface ice that migrates through pores to escape, or from 40-50m below the surface," Deep Impact's chief scientist Mike A'Hearn told the BBC News website.
"I think it is clear from what we have here that the ice that is subliming is within the upper metre. Whether it's 5cm or 20cm below, I wouldn't want to say; but it's not below the top metre. That rules out a lot of the models."
The new results from the mission were presented here at the Lunar and Planetary Science Conference in Houston, Texas.

7 layers, huh. hmmmm. everybody knows that sevens are dear. hmmmm.
.....
At least there is scientific data that should prove useful to science, and understanding ourselves as humans. Hopefully they won't find a way to use comets as weapons. Hopefully that wasn't their intention. hmmmmm

I keep on getting messages that THEY are performing maintenance on this particular blog. And the blog is down to viewers. Here's the message.

The filer that we have been having trouble with in the last few days failed again. Those blogs that are stored on the bad filer are temporarily not available for publishing and viewing. We are working on replacing the filer and restoring access to the blogs affected.
When the message appeared, I went to other blogs, and none of them had the message. I surfed through a LOT of OTHER BLOGS. Guess I'm in the superputer now. Good. Hi superputer. :D

Green Holidays where everybody gets drunk in the month of greenness. Let us not forget the Carnivales and Mardi Gras, Purim and St. Patricks Day, and there was a Hindu holiday
http://news.bbc.co.uk/2/hi/in_pictures/4441471.stm
Celebrated in India and Thailand the same day as Purim in which they celebrate by drinking and covering each other with coloured powder.
http://news.bbc.co.uk/1/shared/spl/hi/pop_ups/06/south_asia_holi0_hindu_festival_of_colours/html/1.stm
"The Hindu festival of Holi marks the start of spring. The colours signify the blossoms of the season. Here children in the Indian city of Amritsar dress as the Hindu god Krishna and his consort Radha."
"The story of Holi: An evil king tried to kill his son, Prahalada, and asks his sister, Holika who he believes is immune to fire, to sit with his son in the fire. But Prahalada survived. Holika died."
'Tis I do believe the same parable as Purim, with evil king and everything.
Somebody I was speaking to recently said I was really stretching it, trying to point out the connections between everything. And that if we just go on our instinct, then we've got nothing to worry about. Then I realized how really really, we don't accept each other for what we are. Really what I'm doing is presenting information. Yes, the information is coloured with my own perception. But also, there is a very viable connection here which is not really acknowledged by humanity as a whole. Everybody just sees their own ways, and ignores the others. Can you imagine my telling Rabbi G that the Hindu Holiday celebrating Spring is the same as Purim? I'd be excommunicated from Judaism, wouldn't I.
As far as Adar goes, I'm seeing the paradox more than the joy. The joy is there, but fleeting.
And religion is really getting to me these days. sighs. Everybody insists that they are right. sighs. So I blog this stuff. I'm a teacher and a seeker. And a researcher. I'm a good researcher.

You are an excellent researcher.. i love this blog so much.. I am so glad its back up...
you and me and a comet makes three, lets go for a ride, sit side by side on our comet and fly off to the universes we know live inside...
:-) I too am obsesed with comets and stardust..
I think its a mystics thing..
