Orion "Bullets"

Thanks to adaptive optics:

http://www.space.com/scienceastronomy/0703...ic_bullets.html

most detailed look yet at supersonic “bullets” of gas piercing through dense clouds of hydrogen gas in the Orion Nebula.

Each bullet is about ten times the size of Pluto’s orbit around the Sun and travels through the clouds at up to 250 miles (400 kilometers) per second —or about a thousand times faster than the speed of sound.

The bulk of both the bullets and the surrounding gas cloud consists of molecular hydrogen. The tip of each bullet is packed with iron atoms that are heated by friction and glow bright blue in the new image

As the bullets plow through the clouds, they leave behind tubular orange wakes, each about a fifth of a light-year long.

Astronomers think the enormous clumps of gas were ejected from deep within the nebula following some unknown violent event about a thousand years ago.

“This level of precision will allow the evolution of the system to be followed over the next few years, for small changes in the structures are expected from year to year as the bullets continue their outward motion...”

We'll keep watching.  8)

From March 19 partial solar eclipse [see caption in link below]:

Gorgeous photo; frameworthy.  smile

I think of these as "cookie bite eclipses."   tongue

Japan's "Hinode" (which means "sunrise") returning some surprising results, one of which concerns activity in the chromosphere.  Will download that movie later (can't spare the time/energy with work-related downloading).  Cool.  smile

A magnetic vortex almost as big as Earth races across your computer screen, twisting, turning, finally erupting in a powerful solar flare.

This particular movie is visually stunning, but the most amazing thing about it, notes Davis, is where the scene unfolded--in the sun's chromosphere. "We used to think the chromosphere was a fairly uneventful place, but Hinode is shattering those misconceptions."

Further into the article:

There is nothing gentle, however, about "spicules" shooting into the chromosphere from the underlying photosphere. "These are jets of gas as big as Texas," says Davis. "They rise and fall on time scales of 10 minutes."

I don't remember exactly when or why it started, but I haven't been able to access any of the Imaginova websites (imaginova.com, space.com, livescience.com) for over a year now.

My computer seems to refuse their existence. I've never had any trouble with others.

Anyone have an idea why?

Sorry, no.  I'm still able to pull up space.com and livescience.com with zero trouble and no hitches ever.

Hopefully someone can help you troubleshoot the problem.  Good luck.

Here's a rarity:

PLUTO OCCULTATION: On Sunday morning, March 18th, Pluto will pass directly in front of a star in the constellation Sagittarius. This occultation will be visible through large backyard telescopes in the western United States, offering a rare look into Pluto's surprising atmosphere. Experienced amateur astronomers are encouraged to observe.

From Io:

http://www.spaceref.com/news/viewsr.html?pid=23601

Oh gosh!  The "complicated wispy texture" of Tvashtar's plume is an ongoing mystery.  Can see a bright spark beneath, which is lava.  The shadow of Io's limb slices across the plume.  Mentions illumination by "Jupiter light."  The spew from two other volcanoes is also visible (one just barely) in this newly released photo.

Other info too.

Excellent.   B)

Huge seas on Titan:

http://www.space.com/scienceastronomy/0 … lakes.html

Unsure if they're fluid filled or not.

One of the seas [image] is larger than any of the Great Lakes in North America and possibly only slightly smaller than the Caspian Sea

located near Titan's north pole, and one of them measures at least 39,000 square miles

There is no proof yet that these seas contain liquid, but their shape and darkness indicate smoothness, and other properties point to the presence of liquid

The seas discovery has prompted Cassini mission engineers to repoint Cassini's radar instrument to pass directly over the dark areas during a May flyby of the moon.

Enceladus heat from radioactive decay?

http://www.space.com/scienceastronomy/0703...ladus_heat.html

Scientists believe heat from radioactive decay...shortly after it formed billions of years ago may explain why geysers are erupting from the surface today.

raising the possibility that the moon, which has an overall surface temperature of about minus-330 degrees, may have an internal environment suitable for primitive life.

a new model suggests ancient radioactive decay played a key role in shaping the moon's warm south pole region...According to the theory, Enceladus formed some 4.5 billion years ago by the mixing of ice and rock containing radioactive isotopes of aluminum and iron. Over a period of several million years, the rapid decay of the isotopes produced a burst of heat that resulted in a rocky core enclosed by an ice sheet. Over time, the remaining decomposition in the core further warmed and melted the moon's interior.

“It tells us that conditions inside Enceladus either were or still are conducive to biochemical reactions"...Cassini scientists plan to measure the composition of the gas rising from the plume during an Enceladus flyby in 2008.

Yep, Tvashtar stole the spotlight.  wink

http://science.nasa.gov/headlines/y2007 … olcano.htm

Now they estimate the Tvashtar plume in the pic is 180 miles tall -- 30 miles higher than previously estimated.  They point out "grand old Prometheus" at 9 o'clock; they were hoping to get a photo of it erupting -- sure enough.  But Tvashtar far "outshines" Prometheus and scientists are absolutely delighted with the image.

They're wondering if the material spewed from Tvashtar becomes sulfurous snow in the venting process (altitude)...

Got lucky on that flyby.  smile

p.s.: cIclops, that is a great image of the Little Red Spot.

Well we used to have a HUGE surplus (which could have kept 3 generations of Americans comfortably retired/Social Security healthy)...now we're zillions of dollars in debt.

But what do Bush and his cronies care?  They're gazillionaires with utmost financial security.  Guess the rest of us can eat cake or whatever.

Ann Coulter slams (again) liberals and global warming:

http://news.yahoo.com/s/ucac/20070301/c … hemeattofu

Forget the lunacy of people claiming to tell us the precise temperature of planet Earth in 1918 based on tree rings. Or the fact that in the '70s liberals were issuing similarly dire warnings about "global cooling."

They want us to starve the productive sector of fossil fuel and allow the world's factories to grind to a halt.

There are more reputable scientists defending astrology than defending "global warming"

  lol

They think they can live in a world of only Malibu and East Hampton -- with no Trentons or Detroits. It does not occur to them that someone has to manufacture the tiles and steel and glass and solar panels that go into those "eco-friendly" mansions, and someone has to truck it all to their beachfront properties, and someone else has to transport all the workers there to build it.

Because of the industrialization of agriculture -- using massive amounts of fossil fuel -- only 2 percent of Americans work in farming. And yet they produce enough food to feed all 300 million Americans, with plenty left over for export. When are liberals going to break the news to their friends in Darfur that they all have to starve to death to save the planet?

It seems not to have occurred to the jet set that when California is as poor as Mexico, they might have trouble finding a maid. Without trucking, packaging, manufacturing, shipping and refrigeration in their Bel-Air fantasy world, they'll be chasing the rear-end of an animal every time their stomachs growl

lol

-*-

And a friend posted elswhere:

It's taken ten years, apparently, but finally a group of elite dissident scientists from some of the world's most prestigious seats of learning have managed to persuade Britain's Channel 4 to air a documentary challenging humanity's contribution to global warming.

See THIS SITE.

RESEARCH said to prove that greenhouse gases cause climate change has been condemned as a sham by UK scientists.

A recent United Nations report said humans were very likely to blame for global warming and there was "virtually no doubt" it was linked to man's use of fossil fuels.

But sceptical climate experts say there is little scientific evidence to support the theory.

In fact, they claim global warming could be caused by increased solar activity.

In all things scientific, it's important to differentiate between cause-and-effect and simple associations.
If two things happen, one after the other, does that mean the first event caused the second? No. The two events may be unconnected, and may both have been caused by a preceding event as yet unrecognized.

Ice core samples from Antarctica have been used as proof of how warming over the centuries has been accompanied by raised carbon dioxide levels.

But University of Ottawa professor of paleoclimatology Ian Clark claims that warmer periods of the Earth's history came around 800 years before rises in carbon dioxide levels.

[My emphasis added]

We've been presented by the Global-Warmists with a superficially convincing case that elevated CO2 levels are causing Earth's atmospheric temperatures to rise.
But Professor Ian Clark's claims cast doubt on the cause-and-effect connection between CO2 and temperatures.
If what he says is true, a different trigger may in fact cause both CO2 levels and global temperatures to rise, and his claim that temperatures rise before CO2 levels makes the situation even less certain than we've been led to believe!   

[I'd like to throw in a possible explanation for the temperatures going up before the CO2 levels.
Earth's oceans have a great deal of CO2 dissolved in them. But they can hold more CO2 when they're cold than when they're warm.
What if a presently unknown factor periodically causes the oceans to warm up, in turn causing them to release CO2 they can no longer contain because of the extra warmth?
Just a thought.]

The article goes on to say:

The program also highlights how, after World War II, there was a huge surge in carbon dioxide emissions, yet global temperatures fell.

This alone indicates to me that a direct cause-and-effect relationship between rising CO2 levels and rising temperatures is not as simple and clear-cut as they say it is.

"THE GREAT GLOBAL WARMING SWINDLE"

In a polemical and thought-provoking documentary, film-maker Martin Durkin argues that the theory of man-made global warming has become such a powerful political force that other explanations for climate change are not being properly aired.

I'm inclined to agree with that.

The film features an impressive roll-call of experts, including nine professors – experts in climatology, oceanography, meteorology, environmental science, biogeography and paleoclimatology – from such reputable institutions as MIT, NASA, the International Arctic Research Centre, the Institut Pasteur, the Danish National Space Center and the Universities of London, Ottawa, Jerusalem, Winnipeg, Alabama and Virginia.

Another bunch of scientists who'd better be of independent financial means.  :evil: 
They're gonna need to be!

'I've often heard it said that there is a consensus of thousands of scientists on the global warming issue, that humans are causing a catastrophic change to the climate system,' says an emminent earth science expert. 'Well I am one scientist, and there are many, that simply think that is not true.'




At yet ANOTHER SITE reporting on this program, they comment:

Controversial director Martin Durkin said: "You can see the problems with the science of global warming, but people just don't believe you - it's taken 10 years to get this commissioned.

"I think it will go down in history as the first chapter in a new era of the relationship between scientists and society. Legitimate scientists - people with qualifications - are the bad guys.
"It is a big story that is going to cause controversy.

"It's very rare that a film changes history, but I think this is a turning point and in five years the idea that the greenhouse effect is the main reason behind global warming will be seen as total bollocks.

I think this reference to legitimate scientists being "bad guys" means that scientists who heretically cast doubt on man's role in global warming will be seen as evil (i.e. in the employ of Big Oil) and persecuted by the congregation of the true political faith of 'green globalism'.

Professor Paul Reiter's comments:

He said the influential United Nations report on Climate change, that claimed humans were responsible, was a sham.

It claimed to be the opinion of 2,500 leading scientists, but Prof Reiter said it included names of scientists who disagreed with the findings and resigned from the UN's Intergovernmental Panel on Climate Change, and said the report was finalised by Government appointees.

The CO2 theory is further undermined by claims that billions of pounds is being provided by governments to fund greenhouse effect research, so thousands of scientists know their job depends on the theory continuing to be seen as fact.

They also mention the religious aspects of global warming:

"At the moment, there is almost a McCarthyism movement in science where the greenhouse effect is like a puritanical religion and this is dangerous."

In the programme Mr Calder said: "The greenhouse effect is seen as a religion and if you don't agree, you are a heretic."

He added: "However, I think this programme will help further debate and scientists not directly involved in global warming studies may begin to study what is being said, become more open-minded and more questioning, but this will happen slowly."

I would love to see this program but I doubt it will be aired here in Australia. Our media are almost exclusively controlled by left-wing trendies and man-made global warming is the accepted faith here.
What are the chances of this documentary getting past the censors in America?  :shock:

#43 Re: Not So Free Chat » Canada / U.S. relations » 2007-03-07 13:12:46

I agree with Robert.

Canada is so far advanced beyond Mexico it should be apparent to most everyone.  I live 50 miles north of the Mexican border; that's close enough.

The main issue is culture.  The Canadian culture is one of cooperation.  The Mexican culture is "macho one-upmanship King of the Hill"; they work against each other.  I've seen this culture personally; it's no wonder they cannot get ahead.

Frankly I still think the Canadian border is being scrutinized and "treated equally" to that of Mexico's in order to avoid charges of racism.  roll  Of course those folks would like to see reverse-racism in full swing:  Whitey must submit.

Why is it that every disgruntled minority "gets their own race" so they can make charges of racism? A Mexican is one of three possible races or combinations thereof, either he or she is white, black, or of asian descent, Native Americans came over from Asia during the last ice age, so they count as Asians.

So a white Mexican smuggles himself across the border, he is caught and deported, so he complains bitterly of racism against the "Mexican Race".

I wonder if there is a "Canadian Race" also, or do you have to be poor to qualify as a seperate race?

Oh, I quite agree with this.  Besides, "Mexican" is a term of nationality...not race. 

But to answer your question:  Everyone with blue eyes of European extraction is inherently evil, didn't you know?  All other peoples on Earth are absolute angels by comparison.  Yep, there's a Nazi lurking somewhere deep inside ALL of our heads (never mind that I myself would have been deported and kicked into a Nazi crematory oven)...or so anti-white racists would have others believe.  roll

An illegal immigrant should be deported for breaking the law, regardless of where they are from.  Otherwise they're being given preferential treatment over folks standing in line...folks like my paternal grandfather who had to pass through Ellis Island.

Is there ANYTHING federally supported that has produced positive results, since the Bush Administration came into power? I can't think of ONE. And now, we learn of the scandalous conditions at Walter Reed hospital (and others?) that wounded and tramatized veterans of the "war on terror" and their families are encountering. Incompetence personified at the top: two more years to endure, without hope of any lessons learned....

I totally agree, dicktice.

What a great total Lunar eclipse, we had here in Nova Scotia! Seen from Main Street in front of the theatre, it began to creep up from the lower limb at 5:30 AST just as the full Moon cleared the eastern horizon, went on to full (nothing but a faint dull brownish disk), so I went to the show (a world premier of "The Conclave") and was was just leaving the upper limb as I came out about 8:30.  Sorry, Cindy, that it was over by Moonrise out west, but see that film when it comes to a theatre near you, or on DVD, by all means!

Hi dicktice:  Glad you enjoyed the eclipse.  You're right of course; the eclipse wasn't viewable from here.  The Conclave??  Hmmmm...will check out its description.  I'm picky about movies.  wink  Thanks for the recommendation though.  smile

"Comet Galaxy" being ripped to shreds.  Insights into galaxy de-volution.

The gas and stars of the Comet Galaxy—moving through the cluster at speeds of more than 2 million mph—are being stripped away by the tidal forces of the cluster. Also, the pressure of the cluster’s scorching gas plasma—known as ram pressure stripping—is adding to the damage.  "...situated 3.2 billion light-years from Earth..."

Elliptical galaxies generally have little gas and dust, and mainly consist of old stars. Unlike spiral galaxies, which are generally found in isolation, elliptical galaxies are spotted in the center of crowded galaxy clusters.

Up until now, it’s been a mystery as to how a gas-rich spiral galaxy evolves into a gas- poor irregular galaxy or a gas-poor elliptical galaxy.  Also, when the Universe was half its present age, only one in five galaxies was a gas-poor elliptical galaxy. This has left astronomers wondering where all of the present day elliptical galaxies came from.

Elliptical galaxies, scientists suspect, are transformation products of other types of galaxies, something no one has seen because the process takes billions of years. What they are observing now is some 200 million years into such a process.

The Comet Galaxy—with a little more mass than the Milky Way—will eventually lose its battle against the tidal forces and pressures of the hot plasma acting on it and end up a gas-poor galaxy with a collection of old stars.
