From the Daily Galaxy
by one of my personal fave researcher Rebecca Sato........ Scientists Baffled by Bizarre “Cosmic Powerhouses”
[i][url "http//www.dailygalaxy.com/photos/uncategorized/2007/12/20/suzaku_spacecraft_2.jpg"][img]http//www.dailygalaxy.com/my_weblog/images/2007/12/20/suzaku_spacecraft_2.jpg[/img][/url] “The age of cosmic-ray astronomy has arrived. In the next few years, our data will permit us to identify the exact sources of these cosmic rays and how they accelerate these particles.”

[/i]~ Nobel laureate James Cronin, University Professor Emeritus in Physics at the University of Chicago.
Cosmic powerhouses pour out vast amounts of energy, and they accelerate particles to almost the speed of light. They are the most energetic objects in our galaxy, but scientists are still trying to figure out what they are, and what they’re doing. But so far, these recently discovered objects remain shrouded in mystery. [/url]
Up until this point, the history of astronomical discovery has been dominated by the detection of light. “We are doing astronomy with protons—charged particles,” said Joao de Mello Neto, of the University of Rio de Janeiro in Brazil. “We are opening a new window in astronomy.”
Cosmic rays—consisting mostly of protons—fly through the universe at nearly the speed of light. These rays contain more than one hundred million times more energy than the particles produced in the world’s most powerful particle accelerator. Fortunately, Earth’s atmosphere protects us from their potentially harmful effects. Astrophycicists are eager to unravel the mystery of what is producing these powerful rays.
"Understanding these objects [cosmic powerhouses] is one of the most intriguing problems in astrophysics," explains Takayasu Anada of the Institute for Space and Astronautical Science in Kanagawa, Japan.
However, working in synergy with a ground-based telescope array, the joint Japanese Aerospace Exploration Agency (JAXA)/NASA Suzaku X-ray observatory is beginning to shed some light on the strange celestial objects. They were first discovered in just the last few years by an array of four European-built telescopes named the High Energy Stereoscopic System (H.E.S.S.), located in the African nation of Namibia. H.E.S.S. indirectly detects very-high-energy gamma rays from outer space. These gamma rays are the highest-energy form of light ever detected from beyond Earth, so H.E.S.S. and other similar arrays have opened up a new branch of astronomy.
The image above from Japan's Suzaku X-ray observatory shows RXJ1713.7-3946, a supernova remnant -the gaseous remnant of a massive star that exploded. The remnant is about 1,600 years old. The contour lines show where gamma-ray intensity is highest, as measured by the High Energy Stereoscopic System (HESS) in Namibia.
When Anada and his colleagues pointed Suzaku at a source known as HESS J1837-069 (the name reflects it’s coordinates), the X-ray spectrum closely pulsar wind nebulae, which are gaseous clouds that are sculpted by winds blown off by collapsed stars known as pulsars. Pulsar wind nebulae emit hard X-rays, and their X-ray output remains relatively constant over long timescales. "The origin of the gamma-ray emission from HESS J1837-069 remains unclear, but we suspect that this source is a pulsar wind nebula from the Suzaku observation," says Anada.
A team of researchers led by Hironori Matsumoto of the University of Kyoto in Japan, targeted Suzaku on HESS J1614-518. This source belongs to a class of objects known as "dark particle accelerators" because their ultrahigh energies suggest they are accelerating particles to near-light speed, turning them into cosmic rays.
Although the nature of these objects still remains a mystery, Suzaku’s observations did reveal some secrets, particularly what some powerhouses are producing. When electrons are accelerated to high speeds, they spiral around magnetic field lines that permeate space, generating copious X-rays. Since protons are much more massive than electrons, they emit few X-rays. Matsumoto and his colleagues reported that HESS J1614-518 emits very weak X-rays. "This result strongly suggests that high-energy protons are being produced in this object," says Matsumoto.
Suzaku also observed two other H.E.S.S. dark particle accelerators, but found no obvious X-ray counterparts at the H.E.S.S. positions. These sources must also be weak X-ray emitters, indicating they are also accelerating mostly protons. Using the high sensitivity of the Suzaku satellite, the scientists are planning on finding the strong candidates for the origin of cosmic rays.

There may be evidence here of deeper forces and far more basic function....The possibilities are exciting...However one wonders what science has been thinking all these years with this excellent media (as it were)right under their noses.............
We are all familiar with xrays and such devices....we are sadly lacking in basic inspiration at times....Or perhaps the technology must be sufficient to enable......then we think of this stuff......
At any rate, it looks like well be seeing Gamma ray views of the universe(like the first hubble pics it will be a sensation)
Maybe there is even more of this type of advances in the offing......

(((does anybody EVER READ the Daily Galaxy available in our news section?
It will also send you an refreshing email update every day!
I have not perused one issue that has failed to present me a fascinating insight of some kind!
This news letter is the best ive ever subscribed to.........and its FREE!
If you dont check it out regularly yer missing some great info!))))

First off, thanks Bergle that is amazing.

But, it is not energy which is pouring out, because energy only goes in and does not come out.

It is unfortunate that these scientists are not up to speed on the basic dynamics of universe.

What pours out is a negative..........resistance, increasing resistance with distance.

The universe is a dynamic system and space itself is dynamic which precludes particles traveling vast distances at very close to the speed of light.

This is presented in terms of a linear reference to space and does not allow for a simultaneous view of universe.

The event itself is amazing, but something is lost in the translation............which is unfortunate, but could explain why the scientists are baffled.

Thank you dave,as usual you have "risen to my bait,and given some semblane of a laymans translation into new science terms and termiology.
I keep finding this stuff here and there and presenting it for your and others new slant on it....
Of course anyones interpretATION OF NEW DATA IS VALID,AND I HOPE THERE ARE A FEW MORE OPINIONS....IT ONLY SERVES TO EDIFY US ALL WHEN WE HAVE THESE DISCUSSIONS....
BUT YOU, DAVID, HAVE BEEN A TRUE GENTLEMAN, AND A PATIENT TEACHER ALL THE TIME IVE KNOWN YER POSTS OLD BEAN....FOR THAT WE ALL THANK YOU.....
BERGLE
