Eye Of Sauron Homework Assignments

The Russian Orthodox Church has warned of dire consequences for Moscow if plans proceed for a skyscraper light installation modeled on the all-seeing evil eye at the centre of JRR Tolkien’s fantasy novels.

A property company plans to raise what resembles a giant glowing eye on the 21st floor of a skyscraper this week to celebrate the release of the final part of Peter Jackson’s movie adaptation of The Hobbit.

In The Hobbit and also in Tolkien’s subsequent trilogy, Lord of the Rings, the Eye of Sauron is a giant flaming eye controlled by the “dark lord” Sauron, which allows him to watch anyone who puts on the fateful, power-giving ring at the novels’ center.

The installation is planned as a 1 metre (3.3 foot) sphere on top of a 21 storey building, with a light show projected from behind to create a 3-D effect, said Polina Murova, a spokeswoman for the property company behind the stunt.

But for the Russian Orthodox Church, the evil eye is no fiction.

“This is a demonic symbol,” the Russian Orthodox Church’s head of public affairs, Vsevolod Chaplin, told Govorit Moskva radio station.

“Such a symbol of the triumph of evil is rising up over the city, becoming practically the highest object in the city. Is that good or bad? I’m afraid it’s more likely bad. Just don’t be surprised later if something goes wrong with the city.”

The eye is due to be switched on Thursday evening and to remain lit for seven hours, the property company that owns the tower, Hals Development, announced, saying it was designed by a group of designers called Svecheniye, or Radiance.

Murova insisted the project was “not a promotion” for the film and that the designers were simply fans who had approached the company with the idea.

Whether divine intervention was involved was unclear, but forecasts of heavy snowfall were threatening to scupper the project, Murova said.

Jackson’s The Hobbit: The Battle of the Five Armies, the final installment of his three-part version of Tolkien’s book, stars Martin Freeman as Bilbo Baggins.

Hobbits and orcs may exist only in fiction, but a real-life supermassive black hole has spawned a structure that looks strikingly like the evil "Eye of Sauron" from J.R.R. Tolkien's "Lord of the Rings" fantasy novels and the films inspired by them.

The black hole sits at the heart of a spiral galaxy called NGC 4151, which is 43 million light-years from Earth. This composite image stitches together data from several different telescopes, revealing a gigantic structure that astronomers say resembles the all-seeing eye of Tolkien's malevolent wizard Sauron.

In the eye's "pupil," X-rays (blue) from NASA's Chandra X-ray Observatory mix with visible-light data (yellow) from the Jacobus Kapteyn Telescope in the Canary Islands, which show emissions of positively charged hydrogen. The red around the pupil shows neutral hydrogen, detected by radio observations from the Very Large Array in New Mexico, researchers said.

A black hole outburst

The X-ray emission near the galaxy's heart was likely caused by an outburst powered by the supermassive black hole, researchers said. Scientists have proposed two different scenarios to explain the X-ray emission.

One possibility is that the central black hole was growing much more rapidly about 25,000 years ago (in Earth's time frame), researchers said. The radiation produced by material falling into the black hole was so bright back then, according to this theory, that it stripped electrons away from atoms in the gas in its path. X-rays were then emitted when electrons recombined with these ionized atoms.

The second scenario posits that material spiraling into the black hole from an accretion disk spawned a vigorous outflow of gas from the surface of this disk. This outbound flow then heated the gas in its path to X-ray-emitting temperatures, researchers said. 

Both of these scenarios predict that an outburst has happened in the relatively recent past. They imply that periods of high activity are common, making up at least 1 percent of the black hole's lifetime, researchers said.

Learning from the Eye of Sauron

NGC 4151 is one of the nearest galaxies that contains an actively growing black hole. Because of this proximity, it offers one of the best chances to study the interaction between an active supermassive black hole and the surrounding gas of its host galaxy, researchers said.

Such interaction, or "feedback," is known to play a key role in the growth of supermassive black holes and their host galaxies. If the X-ray emission in NGC 4151 originates from hot gas heated by the outflow from the central black hole, it would be strong evidence for feedback from active black holes to the surrounding gas on galactic scales, researchers said.

With the Eye of Sauron providing so much potentially useful information, perhaps astronomers will now scan the heavens for Gandalf's Staff, or the Mirror of Galadriel.
