I can confirm the EXACT SAME THING................ IT IS NOT WORKING - appears that portion of the server code has NOT been activated or possibly not installed.

If you try to visit a website and see a “500 Internal Server Error” message, it means something has gone wrong with the website. This isn’t a problem with your browser, your computer, or your internet connection. It’s a problem with the site you’re trying to visit.

...... If you’re a website owner and you’re experiencing this error on your server, there’s no single easy fix. There’s a problem with something, and it could be many things. Common problems include an error in your website’s .htaccess file, incorrect permissions on files and folders on your server, a software package that your website depends on not being installed, or a timeout when connecting to an external resource.

You’ll need to examine your web server’s log files and do more troubleshooting to determine the specific cause of the problem and its solution.

Wild Milky Way Map Reveals Hidden Loops of Multicolored Microwaves
Currents of bold color swirling in the image above look like an impressionist's painting, but are actually a map of microwaves emanating from the Milky Way galaxy.

This vivid snapshot captures light radiating outward as charged particles zip through in the galaxy's magnetic fields. The low-energy light waves also reveal the presence of a ring of dust that cordons off a third of the sky.

Dr. Newberg was mentioned in RPI's on-line newsletter on 2015-03-09: The Corrugated Galaxy—Milky Way May Be Much Larger Than Previously Estimated
Findings Led by Rensselaer Polytechnic Institute Researchers Published in the Astrophysical Journal

The Milky Way galaxy is at least 50 percent larger than is commonly estimated, according to new findings that reveal that the galactic disk is contoured into several concentric ripples. The research, conducted by an international team led by Rensselaer Polytechnic Institute Professor Heidi Jo Newberg, revisits astronomical data from the Sloan Digital Sky Survey which, in 2002, established the presence of a bulging ring of stars beyond the known plane of the Milky Way.

PLEASE READ POST# 62152 "Message boards : Number crunching : Malware Concerns over Bitcoin Utopia"
Both Adaware and Spybot tell me that the BitCoin Utopia download contains a Trojan,so much as I'd love to contribute, I think I'll pass

keputnam Bitcoin Utopia does not contain a Trojan. It is a false flag. Just exclude the Boinc directories and it'll stop.

Posted 22 Mar 2014 by Dr Who Fan
NASA has launched an interactive map of the Milky Way galaxy, constructed over the course of 10 years from more than 2 million infrared images from the Spitzer Space Telescope.

Most of us will never leave the Earth -- but that doesn't stop us dreaming of the stars. There are a few tools that let you explore, though -- and NASA has just launched a killer.

Created from the Galactic Legacy Mid-Plane Survey Extraordinaire (Glimpse) project, it's the most comprehensive visual map of the Milky Way Galaxy released to date -- and yet it only shows just over half of the galaxy's stars. Stitched together from more than 2 million images taken by the Spitzer Space Telescope over the course of a decade, the zoomable, 360-degree image comes in at 20 gigapixels. Since its launch in 2003, Spitzer has spent a total of 4,142 hours taking pictures of the Milky Way in infrared light.

"If we actually printed this out, we'd need a billboard as big as the Rose Bowl Stadium to display it," Spitzer Space Science Center imaging specialist Robert Hurt said in a statement. "Instead we've created a digital viewer that anyone, even astronomers, can use."

Posted 12 Feb 2014 by Dr Who Fan
Four years ago, Anna Frebel, a young astronomer at the Massachusetts Institute of Technology, found an ancient star in a neighboring galaxy whose chemical composition proved nearly identical to some unusual stars on the outskirts of our own galaxy, which are older than the Milky Way itself

It was a striking discovery, suggesting that the relatively young Milky Way is growing by conquest — “cannibalizing” nearby older dwarf galaxies. And it underscored the importance of a new way of learning how the universe evolved from the Big Bang to the modern cosmos.

Posted 21 Dec 2013 by Dr Who Fan
The European Space Agency successfully put its Gaia satellite into orbit, with the hopes of unrolling a stunning map of the Milky Way in 3D.

The Milky Way is about to be seen in a whole new way.
The European Space Agency has successfully launched its Gaia satellite into orbit, bringing a 1 billion-pixel camera detector to map our galaxy in 3D.
The stargazer lifted off on Thursday aboard a Soyuz-Fregat rocket from a launch pad at Sinnamary in French Guiana. Its mission is to map the precise location of over a billion stars.
Its instruments are expected to help discover planets, asteroids, and supernovas, as well as reveal a better understanding of the origin and structure of the Milky Way.

Posted 15 Dec 2013 by Dr Who Fan
Astronomers have pieced together a detailed picture of how our Milky Way galaxy came together, using Hubble Space Telescope photos of 400 similar galaxies at various stages of evolution.

"For the first time we have direct images of what the Milky Way looked like in the past," study co-leader Pieter van Dokkum, of Yale University in New Haven, Conn., said in a statement.

"Of course, we can't see the Milky Way itself in the past. We selected galaxies billions of light-years away that will evolve into galaxies like the Milky Way," van Dokkum added. "By tracing the Milky Way's siblings, we find that our galaxy built up 90 percent of its stars between 11 billion and 7 billion years ago, which is something that has not been measured directly before."
