Astrophile: A scorched world with snow black and smoky

Astrophile is our weekly column on curious cosmic objects, from the solar system to the far reaches of the multiverse

Object: Titanium oxide snow
Location: The hot-Jupiter planet HD 209458b

There is something magical about waking up to discover it has snowed during the night. But there's no powdery white blanket when it snows on exoplanet HD 209458b. Snow there is black, smoky and hot as hell – resembling a forest fire more than a winter wonderland. Put it this way: you won't be needing mittens.

HD 209458b belongs to a family called hot Jupiters, gas-giant planets that are constantly being roasted due to their closeness to their sun. By contrast, the gas giants in our immediate neighbourhood, including Jupiter, are frigid, lying at the solar system's far reaches.

HD 209458b is also noteworthy because it is tidally locked, so one side is permanently facing towards its star while the other is in perpetual night. On the face of it, these conditions wouldn't seem to invite snow: temperatures on the day side come close to 2000° C, while the night side is comparatively chilly at around 500° C.

Snow made of water is, of course, impossible on this scorched world, but the drastic temperature differential sets up atmospheric currents that swirl material from the day side to night and vice versa. That means that any substances with the right combination of properties might be gaseous on the day side and then condense into a solid on the night side, and fall as precipitation. Say hello to titanium oxide snow.

Stuck on the surface

Although oxides of titanium make up only a small component of a hot Jupiter's atmosphere, these compounds have the right properties to fall as snow. But there was a snag that could have put a stop to any blizzards. Older computer models of hot Jupiters suggested that titanium oxides condensing in the air on the night side would snow – and remain on the relatively cool surface forever. "Imagine on Earth if you had no mechanism to evaporate water, it would never rain," says Vivien Parmentier of the Côte d'Azur Observatory in Nice, France.

Now he and colleagues have created a more detailed 3D computer model that shows that the snow can become a gas again as it falls and the temperature and pressure increase. Strong updraughts can then blow the titanium oxides back to the upper atmosphere. "The gas can come back on the top layers and snow again and again," says Parmentier.

Snowfall on HD 209458b would be like none you've ever seen. Though titanium dioxide is white and shiny, for example, the snowflakes would also contain silica oxides from the atmosphere, making them black. Since the atmosphere is also dark, snowstorms on the planet would be a smoky affair, the opposite of the white-outs we get on Earth. "It would be like being in the middle of a forest fire," says Parmentier.

Although the team studied a particular hot Jupiter, their model should apply equally to other planets of this type, suggesting hot snow is a common occurrence. Parmentier says we may have already spotted snow clouds on another hot Jupiter, HD 189733b, as spectral analysis of the planet suggests the presence of microscopic particles in its atmosphere.

David Sing of the University of Exeter, UK, who helped identify such particles on HD 189733b, says the team's new model goes a long way to explaining how titanium oxides behave on hot Jupiters. "We're pretty used to water condensing on Earth; there it is titanium because the temperatures are so much hotter."

Hot, black snow – now that would be something to wake up to.

Cambodians bid farewell to ex-king ahead of cremation

PHNOM PENH: Thousands of Cambodians paid their last respects to their beloved former king Norodom Sihanouk as his body lay in state Saturday ahead of his cremation next week.

The mourners were able to glimpse the late monarch's gilded casket through doorways to the purpose-built crematorium where it was carried Friday in a lavish procession that brought Phnom Penh to a standstill.

His body will be kept at the crematorium until Monday when his wife and his son, current King Norodom Sihamoni, will start the cremation ceremony.

"I had the chance to pay my last respects to the King-Father," 65-year-old Sun Sopho, told AFP, with tears in her eyes, reflecting the sorrow of many who see Sihanouk as a force of stability over six turbulent decades.

"I asked his soul to bless us and to keep peace for the country forever."

The mercurial ex-monarch died of a heart attack aged 89 in Beijing on October 15 last year.

Sihanouk was just 18 when placed on the throne in 1941 by French colonial authorities, but quickly defied his patron's expectations of a pliant king.

A father of 14 children over six marriages, Sihanouk abdicated in 2004 after steering Cambodia through six decades marked by independence from France, civil war, the murderous Khmer Rouge regime, his own exile and finally peace.

Sihanouk -- a self-confessed "naughty boy" who loved to direct films, write poetry and compose songs -- remained hugely popular among Cambodians. But his record is not without controversy.

After being ousted by the US-backed General Lon Nol in 1970, he aligned himself with the Khmer Rouge, only to be placed under house arrest as the communist regime terrorised the nation.

Before the Vietnamese toppled the Khmer Rouge in 1979, Sihanouk took exile in China. He regained his throne in 1993, although his influence was greatly diminished and he abdicated in 2004 to be succeeded by Sihamoni.

Clinton's final day in job marred by bombing

STORY HIGHLIGHTS

• NEW: Kerry sworn in, first trip likely to include stops in Egypt and Israel


• Clinton cites Turkey attack as example of challenges in the world


• Clinton visited 112 countries and flew almost 1 million miles in four years


• At 65, Clinton faces questions about whether she'll run for president in 2016

Washington (CNN) -- A final meeting with the president. A farewell address to the State Department staff. A terrorist attack at the U.S. Embassy in Turkey.

Hillary Clinton's last day as secretary of state on Friday seemed to be a microcosm of her four globe-trotting years as America's top diplomat.

The former first lady had a full schedule, as usual, meeting in private with President Barack Obama at the White House and then attending the send-off ceremony with clapping, cheering workers at the agency she led.

Those events were clouded by a suicide bombing earlier in the day in Ankara that killed the attacker and a Turkish security guard at the embassy. No Americans were killed or injured.

Clinton traveled nearly 1 million miles and visited 112 countries in her quest as secretary to promote better understanding of the United States and its role in the world.

On the road with Hillary Clinton

However, her tenure will also be remembered for last September's attack on a diplomatic compound in Benghazi, Libya, that killed Ambassador Christopher Stevens and three other Americans.

Amid the good wishes and emotions of Clinton's farewell, Friday's bombing in Turkey was a grim reminder of the continuing threats and challenges to U.S. diplomatic efforts.

"Of course we live in very complex and dangerous times as we saw again just today at our embassy in Ankara," Clinton told the State Department ceremony.

"I know the world we are trying to help bring into being in the 21st century will have many difficult days," she added. "But I am more optimistic today than I was when I stood here four years ago."

Standing in front of a sign that said "Thank You," Clinton told the staffers jamming the area that she would miss them and the important work they do around the world.

"I will probably be dialing ops just to talk," she said to laughter.

Clinton sent her resignation letter to Obama a few hours before her successor, John Kerry, was sworn in on Friday afternoon.

Opinion: Clinton, secretary of empowerment

"It has been an honor to serve in your administration and to represent our country around the world," the letter said.

"I am proud of what we have accomplished together on behalf of the American people and in pursuit of our interests and values. And I am more convinced than ever in the strength and staying power of America's global leadership and our capacity to be a force for good around the world," she said.

In what was billed as Clinton's farewell speech on Thursday at the Council on Foreign Relations, she said the United States needs to build "smart power" in a world where the levers of influence are changing rapidly.

American diplomats have to work with entrepreneurs and activists, use new technological tools such as social media and update the global and regional institutions that have dominated international affairs since World War II, Clinton said.

"We need a new architecture for a new world -- more Frank Gehry than formal Greek," she said. "Now some of his work at first might appear haphazard, but in fact, it's highly intentional and sophisticated. Where once a few strong columns could hold up the weight of the world, today we need a dynamic mix of materials and structures."

Clinton defends her diplomatic legacy

Clinton called the United States "uniquely well-positioned" to help construct that metaphorical global edifice.

"Those things that make us who we are as a nation --- our openness and innovation, our diversity, our devotion to human rights and democracy --- are beautifully matched to the demands of this era and this interdependent world," she said.

Kerry, who served nearly 30 years in the Senate, stepped down Friday ahead of his swearing-in as the nation's 68th secretary of state.

He was chairman of the Senate Foreign Relations Committee and the Democratic nominee for president in 2004, when he lost to incumbent President George W. Bush.

Kerry expects to take his first official overseas trip in coming weeks, according to a U.S. official who said stops would likely include Israel and Egypt.

Exiting State, Clinton looks to writing, speaking

Clinton, 65, now faces persistent questions about whether she will mount a second White House run in 2016 to break perhaps the highest remaining glass ceiling.

"Well I'm not thinking about anything like that right now. I'm looking forward to finishing my tenure as secretary of state and catching up on 20 years of sleep deprivation," Clinton said Tuesday at a global "town hall" forum in Washington.

Observers note her answer was a less emphatic denial than previous responses that seemed to rule out any possibility of reentering the political fray.

According to a CNN/ORC International poll conducted last month, 85% of Democrats and independents who lean toward the Democratic Party said they would be very or somewhat likely to support Clinton if she sought the Democratic nomination.

Clinton was considered a favorite in 2008, but Obama, who served with her in the Senate, got an early jump in the primaries. Clinton was unable to capture the momentum in a fierce political battle.

Despite the rugged campaign, Obama chose Clinton for his Cabinet and she embraced the role.

In a joint interview with CBS that aired on Sunday, Obama said that he believes Clinton's legacy will rank among the best.

"It has been a great collaboration over the last four years," Obama said. "I'm going to miss her."

Twitter: 250,000 users' data compromised in hacking attacks

#1157946: Twitter bird logo, social networking and microblogging service, graphic element on white / AP Graphics

Twitter said today that it recently detected a series of attempts to hack into user data, and that the attackers may have successfully absconded with some users' information.

In a blog post Friday afternoon, Twitter explained the situation, and the steps it has taken to fight off the hackers.

This week, we detected unusual access patterns that led to us identifying unauthorized access attempts to Twitter user data. We discovered one live attack and were able to shut it down in process moments later. However, our investigation has thus far indicated that the attackers may have had access to limited user information - usernames, email addresses, session tokens and encrypted/salted versions of passwords - for approximately 250,000 users. As a precautionary security measure, we have reset passwords and revoked session tokens for these accounts. If your account was one of them, you will have recently received (or will shortly) an email from us at the address associated with your Twitter account notifying you that you will need to create a new password. Your old password will not work when you try to log in to Twitter.

Twitter said in the post that a very small number of users were affected by the hacking, but it encouraged everyone who uses the service to ensure that they are practicing "good password hygiene, on Twitter and elsewhere on the Internet." Among its suggestions: using unique passwords of at least ten characters, including a mix of upper and lower case letters, numbers, and symbols. Based on attacks on other high-profile tech and media companies, Twitter also said it is recommending the U.S. Department of Homeland Security's recent advisory on disabling Java, among other precautions.

This attack was not the work of amateurs, and we do not believe it was an isolated incident. The attackers were extremely sophisticated, and we believe other companies and organizations have also been recently similarly attacked. For that reason we felt that it was important to publicize this attack while we still gather information, and we are helping government and federal law enforcement in their effort to find and prosecute these attackers to make the Internet safer for all users.

Gov's Handling of Sandusky Case Under Investigation

The newly-elected attorney general of Pennsylvania is going after the state's governor, Tom Corbett, who was attorney general when child sex allegations against Penn State coach Jerry Sandusky were first brought forward.

Kathleen Kane, a Democrat who was sworn in as attorney general on Jan. 15, said that she will name a special prosecutor in the coming days to investigate Corbett's handling of the Sandusky case. Corbett is a Republican.

The investigation will look specifically at why it took the attorney general's office three years to bring criminal charges against Sandusky while he continued to have access to children.

"Attorney General Kane will appoint a special prosecutor to lead the office's internal investigation into how the Sandusky child abuse investigation was handled by the Office of the Attorney General," Kane's office said in a statement released today.

Corbett's attorney general's office was first notified of the allegations against Sandusky in 2008 when a high school student told his mother and school that Sandusky had molested him. The local district attorney passed the allegation on to the attorney general, then Corbett. Corbett convened a grand jury.

It wasn't until 2011 that sex abuse charges were filed against Sandusky while Corbett had since become governor. Sandusky was convicted on 45 counts of sex abuse in June 2012.

The charges sent shockwaves throughout Pennsylvania, as Penn State's president, two top officials, and legendary coach Joe Paterno all lost their jobs over the scandal.

"Why did it take 33 months to get Sandusky off the streets? Was the use of a grand jury the right decision? Why were there so few resources dedicated to the investigation? Were the best practices implemented?" the statement from Kane's office read.

"At the end of this investigation, we will know the answers to these questions and be able to tell the people of Pennsylvania the facts and give them answers that they deserve," the statement said.

Describing an interview Kane gave the New York Times, the Times said Kane suggested that Corbett did not want to upset voters or donors in the Penn State community before his gubernatorial run in 2009.

Corbett has denied those suggestions. His office did not immediately return calls for comment.

Kane's office preemptively fought back against the idea that the investigation is politically motivated. Kane, a Democrat, defeated the incumbent attorney general, Linda Kelly, a Republican in November 2011. Corbett is a Republican.

"The speculation that this is about politics is insane," a staff member in Kane's office told ABC News today. "You go anywhere in Pennsylvania and anywhere across the country and you'll find individuals asking, 'why did it take three years? Why was there a grand jury? Why make these kids talk to 30 different people about what happened?"

Swarm-mongering: Brainless blobs flock together

Birds of a feather flock together and now so do brainless, inanimate blobs. Made of microscopic particles, the artificial swarms could shed light on the mysterious mechanisms behind the natural swarming seen in fish and birds. They might also lead to materials with novel properties like self-healing.

Animals such as birds, fish and even humans that move together in swarms have individual intelligence, but Jérémie Palacci of New York University and colleagues wondered whether inanimate objects could also swarm. "From a physicist's point of view, if many different systems behave in the same way there must be an underlying physical rule," he says.

To explore this idea, the team created microscopic plastic spheres, each one with a cubic patch of haematite, an iron oxide, on its surface. When submerged in hydrogen peroxide, the spheres spread out in a disordered fashion. The team then shone blue light on the particles, causing the haematite cubes to catalyse the breakdown of any nearby hydrogen peroxide into water and oxygen. As hydrogen peroxide concentration dropped temporarily in these regions due to the reaction, osmotic forces cause more hydrogen peroxide to flow into them, and that in turn buffets the spheres. The whole process then repeats.

Self-healing swarm

When two spheres come close enough to each other, the balance of chemical forces shifts so that the two spheres are attracted. If there are enough spheres in the same place they will cluster together to form shapes of symmetrically arranged particles, which the team call crystals (see video, above). These crystals continue to be buffeted by the movement caused by the breakdown of hydrogen peroxide – but now they move together as one object, replicating a life-like swarm. Switch off the light, however, and the reaction stops, causing the crystal to lose the forces that hold it together, and the particle distribution becomes disordered once again.

"This system shows that even though the particles have no social interaction or intelligence, you can exhibit collective behaviour with no biology involved," says Palacci. Since the haematite is magnetic, it is even possible to steer the crystals in one direction by applying a magnetic field. Such control might be useful if the artificial swarms are to be harnessed for applications.

As the particles automatically fill any gaps that form in the crystal, again thanks to the chemical dynamics of the system, they could be used to create a self-assembling, self-healing material. The work is published in the journal Science today.

Schooled by fish

Iain Couzin of Princeton University says these kinds of systems are very useful for studying biological collective behaviour because researchers have complete control over their interactions – unlike natural systems.

His team has its own swarming experiment published in the same issue of Science, based on schools of fish that prefer to stay in shade. Their paper shows that shining a light on some of the fish in the school causes them to speed up, to get away from the light. But as a result, non-illuminated fish also speed up, even though, if acting purely as individuals, they would have had no reason to do so. "We show just by using simple interactions that schools can have a sense of responsiveness to the environment that individuals do not have," he says.

Couzin sees no reason why such behaviour should be limited to natural systems. "In future it may be possible to create systems of particles that can make collective decisions – something we often think of as only possible in biological systems," he says.

"The sooner, the better" for COC on South China Sea: Shanmugam

SINGAPORE: Foreign Affairs Minister K Shanmugam has reiterated the need for a Code of Conduct (COC) on the South China Sea, saying the sooner it is started the better.

He said this in a live interview with the BBC on Friday morning, covering issues such as the South China Sea claims, US-China relations and ASEAN.

He was asked whether it is possible to have some kind of resolution via ASEAN.

Mr Shanmugam replied that ASEAN has been trying to make it clear that territorial disputes can only be solved by the claimant states themselves.

But the regional grouping can put in place a structure that shows and tells people how they have to structure their conduct with each other. And this is why ASEAN has been pushing for the COC.

Mr Shanmugam said the COC should apply to all countries in the way they interact with each other in the region.

Asked how concerned Asia should be over what's perceived as an increasingly assertive China, Mr Shanmugam said this has to be looked at in context.

He said no leader of China, as well as leaders of many countries, can afford to be seen to be soft on sovereignty.

The real issue is whether they can put in place a modus vivendi to deal with territorial and sovereignty issues.

Mr Shanmugam pointed out that the actual disputes will take a very long time to settle and stressed that the issue is how countries behave so that the disputes do not escalate into clashes, which could be terrible for the region.

A photo of Caleb Moore's performance in the Snowmobile Freestyle Final during X Games Aspen 2013.

STORY HIGHLIGHTS

• NEW: Caleb Moore's brother also suffered an accident in the X Games


• Caleb Moore died a week after a snowmobile crash in the X Games


• The crash has raised new safety concerns about the games


• ESPN, which operates the X Games, says it will conduct a thorough review

(CNN) -- Snowmobiler Caleb Moore died Thursday, a week after a crash that has raised new safety concerns about the X Games. He was 25 years old.

"He will be truly missed and never forgotten," his family said in a statement.

"The family wishes to express their deep gratitude for all the prayers and support they have received from all the fans, friends and family around the world that Caleb has inspired. ... Arrangements for a celebration of life are being made and an announcement will be made in the coming days."

Moore, a freestyle snowmobiler, was attempting a backflip at the Winter X Games in Aspen, Colorado, when he couldn't rotate his machine enough to land properly. The skis dug into the lip of the slope, bringing the 450-pound snowmobile crashing down on him. The vehicle slammed into Moore's head and chest.

"We are deeply saddened by Caleb Moore's passing and our thoughts and prayers go out to his parents, Wade and Michelle, his brother, Colten, and the entire Moore family," ESPN, which organizes and televises the X Games, said in a statement. "He will be remembered for his natural passion for life and his deep love for his family and friends, and he will always be an inspiration to everyone he touched in the action sports community.

"As a result of this accident we will conduct a thorough review of this discipline and adopt any appropriate changes to future X Games."

The statement added that the X Games have long worked on safety issues and that nevertheless, "when the world's best compete at the highest level in any sport, risks remain. Caleb was a four-time X Games medalist attempting a move he has landed several times previously."

Colten Moore, 23, was also involved in an accident during Thursday's event. He was released from the hospital Saturday, according to his Facebook fan page.

Caleb Moore's Facebook page is carrying messages from fans. "R.I.P. Caleb," wrote Candi Clark-Hibbs, adding, "prayers to your family."

Alaska Airlines plane lands safely after pilot passes out

Updated 3 a.m. EST

PORTLAND, Ore. An Alaska Airlines jetliner bound for Seattle made an emergency landing in Portland, Ore., Thursday night after the pilot lost consciousness, an airline spokesman said.

The co-pilot landed Flight 473 safely after declaring an emergency to get priority care for the pilot, spokesman Paul McElroy said. All of the airlines' pilots are trained to fly single-handedly.

The pilot lost consciousness "somewhere over Oregon," McElroy said, then later regained consciousness and left the cockpit. A doctor on board the flight tended to him in the cabin until the plane landed and was met by medical personnel on the runway.

The pilot, who was not identified, was taken to a hospital but there was no immediate word on his condition, McElroy said.

The Boeing 737-700, with 116 passengers and five crew members on board, left Los Angeles about 6:30 p.m. and was diverted to Portland, touching down there at about 9 p.m., reports CBS Portland affiliate KOIN-TV. It had been due to arrive in Seattle at 9:30 p.m.

McElroy says the pilot has been flying for Alaska for 28 years and was current on his six-month medical evaluation. The co-pilot is an 11-year Alaska Air veteran.

On Jan. 22, the co-pilot on an Alaska Airlines flight from Seattle to Las Vegas fainted briefly, and the pilot requested emergency landing priority to get prompt medical assistance for him.

"At this point, we do not believe there was a connection between the two incidents," McElvoy said.

Twenty passengers with a tight schedule for connecting flights were put on a Horizon Air shuttle flight to Seattle on Thursday night, the spokesman said.

A new pilot was dispatched to Portland to fly the remaining passengers to Seattle on board the same plane.

Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos

Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.

The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."

Arias' attorneys introduced as evidence photos that Alexander took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.

Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.

Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.

"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.

"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.

Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.

Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."

"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.

Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.

In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.

"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"

"She would not be ready to be baptized in that case," Freeman said.

"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.

"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."

Freeman said that Alexander never confessed to having a sexual relationship with Arias.

Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.

The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.
