Astronomers have found a huge new ring around the planet Saturn. The faint dust ring extends up to 7.4 million miles (12 million km) from the planet and could fit over a billion Earths inside it, making it the largest in the Solar System. It could also solve a mystery about one of Saturn’s moons that has puzzled scientists for centuries.

The ring was found with the help of NASA‘s Spitzer Space Telescope, with details published today in the journal Nature. It is thought to consist of ice and dust from Saturn’s moon Phoebe, which is kicked up by collisions with comets and then drifts in towards the planet. The ring and moon both orbit in a plane inclined at 27 degrees to the other rings.

“This is one supersized ring,” said Dr Anne Verbiscer of the University of Virginia, one of the authors of the paper. Of Saturn’s other rings, the largest is the E-ring, a mere 150,000 miles (240,000 km) in diameter. Jupiter also has “gossamer rings” of a similar diameter to the E-ring. If the Phoebe ring was visible from Earth, it would appear twice as large in the sky as the full Moon.

However the newly found ring is extremely faint. It is made up of dust particles around 10 microns (thousandths of a millimetre) in size, and according to Verbiscer, “In a cubic km of space, there are all of 10-20 particles.” This explains why it has evaded discovery until now. “If you were standing in the ring itself, you wouldn’t even know it.”

The Phoebe ring does not reflect much visible light, but the Spitzer telescope was able to pick up the dust’s faint infra-red glow. The telescope, launched in 2003, orbits the Sun and is roughly 66 million miles (107 million km) from Earth. It is one of NASA’s four Great Observatories.

The discovery could also finally account for the unusual appearance of Iapetus, another of the planet’s moons. When Iapetus was first observed in 1671 by astronomer Giovanni Cassini, its leading side was seen to be much darker than the other. Until now scientists had been unsure why this was. Now it is thought that the moon orbits in the opposite direction to the ring, and as Iapetus moves through the ring, dust builds up on its front surface. Verbiscer likens it to “bugs on a windshield.”

“Astronomers have long suspected that there is a connection between Saturn’s outer moon Phoebe and the dark material on Iapetus,” said Douglas Hamilton, another author of the paper. The material has been found to have a similar composition to Phoebe’s surface. “This new ring provided convincing evidence of that relationship.”

This is the second major discovery for astronomers studying Saturn in the past month. In September, evidence from the Cassini orbiter showed that Saturn’s other rings were far less flat than expected.

The first thing to catch my eye when I approached what used to be a Texeco gas station, was a guy up in a man-lift beside the pump price sign. Seeing heavy equipment being used to change what I thought were the gas prices, I thought, “Gawds, these prices are getting out of hand!”

After stopping in later and talking with the owner, I was impressed by how elated he was on the subject of bank processing fees. This was news to me. So I reported it.

The man-lift I saw earlier is absent from the photograph I took. They had used the lift to change the pump price sign from Texaco to Shell.

The Internet-based group “Anonymous” released a new video on YouTube Monday, announcing international protests outside Church of Scientology centers set for February 10. The video “Call to Action” uses the same computer synthesized voice as a previous video titled “Message to Scientology”, which was posted to YouTube last Monday. The “Message to Scientology” video has been viewed over 1,400,000 times, and the “Call to Action” video has already been viewed over 237,000 times.

Anonymous is taking action against the Church of Scientology in response to what it sees as suppression of freedom of speech on the Internet. The group was first motivated after the Church of Scientology issued a copyright infringement claim to YouTube regarding a promotional video of Scientologist Tom Cruise speaking about his beliefs and using Scientology jargon. The Church of Scientology also issued a legal complaint to the website Gawker.com which is also hosting the video, but Gawker has stated it will not take the video down because it is newsworthy.

Anonymous set up a movement called “Project Chanology” to coordinate their efforts, and took down several Church of Scientology websites through denial-of-service attacks. Members of Anonymous have also participated in prank calls to Church of Scientology centers, as well as protests or “raids” outside Scientology buildings, and have posted some of their exploits to YouTube.

In the “Call to Action” video, Anonymous denies that they are composed solely of “super hackers”, stating “Anonymous is a collective of individuals united by an awareness that someone must do the right thing, that someone must bring light to the darkness, that someone must open the eyes of a public that has slumbered for far too long.” The video goes on to state “We want you to be aware of the very real dangers of Scientology,” citing what they term “gross human rights violations”.

Specific controversial events in Scientology history are cited in the video, including Operation Freakout and Paulette Cooper, and Operation Snow White. Operation Freakout was the name of a Church of Scientology operation whose goal was to “get P.C. [Paulette Cooper] incarcerated in a mental institution or jail or at least to hit her so hard that she drops her attacks.” Paulette Cooper had written a book critical of Scientology called The Scandal of Scientology. Operation Snow White was the name of a Church of Scientology operation where members of the Church’s secretive Guardian’s Office infiltrated United States government agencies in Washington, D.C. including the I.R.S. The F.B.I.’s investigation into Operation Snow White led them to discover the planning of actions taken against Paulette Cooper.

The video concludes by inviting the viewer to “take up the banner of free speech” and protest with Anonymous world wide. In an email to CNET News, Anonymous stated that cities where unknown activities are planned on February 10 include New York City, Montreal, Houston, London, Melbourne, and Los Angeles.

On Friday, two spokespersons for the Church of Scientology commented on the recent actions of Anonymous. A spokesman told News.com.au “These types of people have got some wrong information about us,” and Church spokeswoman Yvette Shank told Sun Media that she regarded members of Anonymous as a “pathetic” group of “computer geeks”. On Monday, Radar reported that the Church of Scientology has asked the U.S. Attorney General‘s office in Los Angeles, the F.B.I., and the LAPD to start a criminal investigation of possible criminal activity related to the Internet attacks. A source told Radar that the Church of Scientology is arguing that the Internet attacks are a form of “illegal interference with business.” Radar also reports that the Church of Scientology is emphasizing its status as a religious organization in the United States, in order to assert that the Internet attacks can be classed as hate crimes.

On Saturday, Mark Bunker of the website XenuTV.com posted a video to YouTube criticizing the illegal actions of Anonymous and suggested legal methods for them to retaliate against the Church of Scientology, including peaceful protesting, writing letters to their government representatives, and persuading the United States government to take away the Church of Scientology’s tax exempt status. In the video, Bunker states “I’m mainly concerned because you shouldn’t be doing things that are illegal, you just shouldn’t. It’s not morally right, and it’s not right when Scientology does it, it’s not right when we do it.” Bunker’s video post has been viewed over 156,000 times. On Sunday, Bunker posted a follow-up video to YouTube where he gives advice to Anonymous on how to peacefully picket. He also provides viewers with resources and weblinks to more information on how to hold a peaceful protest. He concludes this video by imitating Obi-Wan Kenobi‘s Jedi mind trick technique and voice from Star Wars, stating “And if I may, as Obi-Wan, tell you: You will do nothing illegal “.

Violent protests over the burning of a Qur’an by a US church spread on Saturday to the southern Afghanistan city of Kandahar, a day after an angry mob attacked a United Nations compound at Mazar-e-Sharif in northern Afghanistan, killing seven UN workers and four Afghan protesters.

According to Kandahar officials, the protests over the desecration of the Qur’an in Florida a month ago started peacefully but became violent when mobs began roaming the streets, vandalizing buildings and burning cars. Afghan police and US soldiers tried to protect a complex of government buildings when a mob attempted to storm them.

Nine people were killed, and 73 injured. Some witnesses said that people who refused to join the violence were beaten and stoned. Others said Afghan police shot demonstrators. The police have denied shooting anyone. “There [was] gunfire into the air in order to bring the people under control, and luckily not one has been killed as a result of the gunfire,” said Zemarai Bashari, Interior Ministry spokesperson as reported by CNN.

Zalmai Ayoubi, spokesperson for the governor of Kandahar province, said that Afghan police arrested 17 people, seven of whom were armed and are suspects in the shooting of protesters. He blamed Taliban insurgents and their supporters for infiltrating the demonstration.

A Taliban spokesperson, Zabiullah Mojahed, denied that the Taliban was responsible for any deaths during Saturday’s violence: “It was the Afghan police that killed the innocent people of Kandahar while they were expressing their feeling against the burning of holy Quran in Florida.”

Kandahar is seen as a stronghold of the Taliban insurgency and in the last two months the province has seen several assassinations and suicide bombings.

NASA’s Deep Impact probe collided with the comet Tempel 1 on Monday, as intended by scientists. The collision took place at 5:45 UTC and NASA held a press briefing shortly after at the Jet Propulsion Laboratory (JPL) in Pasadena, California, NASA’s non-manned space flight control center. A full-fledged press conference by NASA is scheduled to be at JPL on Monday afternoon at 2 p.m. PDT (9:00 UTC).

The experiment, intending to provide more information about the make up of comets, consisted of a 370 kg projectile being fired at the comet in order to observe and analyse the resultant impact. With information gleaned from the impact, the comet’s general make-up can be established and more accurate hypotheses regarding how the Solar system and the universe came to be.

Ian Narev, the CEO of the Commonwealth Bank of Australia, this morning “unreservedly” apologised to clients who lost money in a scandal involving the bank’s financial planning services arm.

Last week, a Senate enquiry found financial advisers from the Commonwealth Bank had made high-risk investments of clients’ money without the clients’ permission, resulting in hundreds of millions of dollars lost. The Senate enquiry called for a Royal Commission into the bank, and the Australian Securities and Investments Commission (ASIC).

Mr Narev stated the bank’s performance in providing financial advice was “unacceptable”, and the bank was launching a scheme to compensate clients who lost money due to the planners’ actions.

In a statement Mr Narev said, “Poor advice provided by some of our advisers between 2003 and 2012 caused financial loss and distress and I am truly sorry for that. […] There have been changes in management, structure and culture. We have also invested in new systems, implemented new processes, enhanced adviser supervision and improved training.”

An investigation by Fairfax Media instigated the Senate inquiry into the Commonwealth Bank’s financial planning division and ASIC.

Whistleblower Jeff Morris, who reported the misconduct of the bank to ASIC six years ago, said in an article for The Sydney Morning Herald that neither the bank nor ASIC should be in control of the compensation program.

New York –”Buy cheap Viagra through us – no prescription required!” Anyone with an active email account will recognize lines like this one. According to some reports, unsolicited advertisements (spam) for Viagra and similar drugs account for one in four spam messages.

Ever since pharmaceutical giant Pfizer promised to cure erectile dysfunction once and for all with its blue pills containing the drug sildenafil citrate, spammers have tried to tap into male anxiety by offering prescription-free sales of unapproved “generic” Viagra and clones such as Cialis soft tabs. Legislation like the U.S. CAN-SPAM act has done little to stem the tide of email advertising the products.

Now Pfizer has entered a pledge with Microsoft Corporation, the world’s largest software company, to address the problem. The joint effort will focus on lawsuits against spammers as well as the companies they advertise. “Pfizer is joining with Microsoft on these actions as part of our shared pledge to reduce the sale of these products and to fight the senders of unsolicited e-mail that overwhelms people’s inboxes,” said Jeff Kindler, executive vice president at Pfizer.

Microsoft has filed civil actions against spammers advertising the websites CanadianPharmacy and E-Pharmacy Direct. Pfizer has filed lawsuits against the two companies, and has taken actions against websites which use the word “Viagra” in their domain names. Sales of controlled drugs from Canadian pharmacies to the United States are illegal, but most drugs sold in Canada have nevertheless undergone testing by the U.S. Food and Drug Administration. This is not the case for many of the Viagra clones sold by Internet companies and manufactured in countries like China and India. While it was not clear that CanadianPharmacy was actually shipping drugs from Canada, Pfizer’s general counsel, Beth Levine, claimed that the company filled orders using a call center in Montreal, reported the Toronto Star.

For Microsoft’s part, they allege that the joint effort with Pfizer is part of their “multi-pronged attack on the barrage of spam.” As the creator of the popular email program Outlook, Microsoft has been criticized in the past for the product’s spam filtering process. Recently, Microsoft added anti-spam measures to its popular Exchange server. Exchange 2003 now includes support for accessing so-called real-time block lists, or RTBLs. An RTBL is a list of the IP addresses maintained by a third party; the addresses on the list are those of mailservers thought to have sent spam recently. Exchange 2003 can query the list for each message it receives.

Kansas has been denied permission to use two key documents commonly used in the writing of science education standards for states, the National Science Education Standards (published by the National Research Council) and Pathways to Science Standards (published by the National Science Teacher Association). The respective organizations argued that they could not grant the state of Kansas permission to use these documents in the current form of the Kansas Science Educational Standards, as these overemphasize controversy between the scientific theory of Evolution and the argument of Intelligent Design. Moreover, the organizations criticize that the standards in their current form distort the definition of science. The American Association for the Advancement of Science has expressed its support for the decision to deny Kansas the use of copyrighted material, as “the proposed standards misrepresent both the content and the standing of evolution as a scientific organizing principle”.

Proponents of Intelligent Design have characterized the refusal as “an effort to censor the discussion of scientific criticism of Darwinian theory by intimidation and threat”.

This is likely to further delay the ratification of the final vote on the Kansas Science Educational Standards as they will have to be rewritten either to not violate any copyright restrictions or modify their account of evolution and outlook on science. According to University of Kansas professor Steve Case, rewriting the standards will be very difficult, as “there is copyrighted material on every page” of the current document.

This is the second time that Kansas was denied the right to use copyrighted materials in their state standards, following the case in 1999, when Kansas included Creationism, a precursor of Intelligent Design, into the school curriculum. A later school board overturned that directive.

The dispute in Kansas has brought nationwide responses, ranging from a rebuke by the American Association for the Advancement of Science to the creation of internet-sensation Flying Spaghetti Monster mythology (which is lobbying the Kansas School Board to give equal time teaching their creationism theory as well.)
