Barcelona, España — El ayuntamiento de Barcelona ha abierto unas nuevas dependencias tras los cambios de criterio por parte del gobierno para tramitar “los papeles” de inmigrantes en La Casa del Mig en el Parque de la España Industrial. Estas oficinas estarán abiertas desde hoy 20 de abril hasta el próximo 7 de mayo. En la fotografía, realizada a las cinco de la tarde, todavía podía observarse la cola de inmigrantes a la espera de poder obtener papeles. Hasta el parque se habían desplazado varios coches patrulla. Además de la presencia de las fuerzas de seguridad se han habilitado varios servicios portátiles en previsión de la avalancha de inmigrantes que finalmente han acudido.

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.

It has emerged that the 33 Chilean miners trapped underground after the mine they were working in collapsed could be brought to the surface in a shorter time than was initially feared. While officials publicly announced that the men would not be brought to the surface until Christmas, sources inside technical meetings have revealed that they could in fact be on the surface by early November. The news comes as families were allowed to speak by radio-telephone to their trapped loved ones on Sunday. Over the weekend, video images filmed by the miners emerged showing the miners playing dominoes at a table and singing the Chilean national anthem. The miners also used the camera to send video messages to their families on the surface, saying that they regularly broke into tears, but were feeling better having received food and water.

The grainy nightvision images, filmed on a high definition camcorder that was sent down a small shaft to the mine, show the men in good spirits, chanting “long live Chile, and long live the miners.” They are unshaven and stripped to the waist because of the heat underground, and are seen wearing white clinical trousers that have been designed to keep them dry. Giving a guided tour of the area they are occupying, Mario Sepúlveda, one of the miners, explains they have a “little cup to brush our teeth”, and a place where they pray each day. “We have everything organized,” he tells the camera. Gesturing to the table in the center of the room, he says that “we meet here every day. We plan, we have assemblies here every day so that all the decisions we make are based on the thoughts of all 33.” Another unidentified miner asks to rescuers, “get us out of here soon, please.” A thermometer is shown in the video, reading 29.5C (85F).

As the film continues, it becomes evident that the miners have stuck a poster of a topless woman on the wall. The miners appear shy, and one man puts his hand to his face, presumably dazzled by the light mounted on the cameraman’s helmet. One miner sent a message to his family. “Be calm”, he says. “We’re going to get out of here. And we thank you from the bottom of our hearts for your efforts.” Another said that the miners are “sure that there are people here in Chile that are big people, that are powerful people, that are intelligent people, and they have the technology and they will all work together to get us out of here.” Speaking to the camera, one says: “we have had the great fortune that trapped in this mine there are good, professional people. We have electricians, we have mechanics, we have machine operators and we will let you know that while you are working to rescue us on the surface, we are down here ready to help you too.” It has been reported that Mario Gómez, 63, has become the group’s “spiritual leader”, having worked in the mines for over fifty years. He has requested that materials to build a shrine be sent down to the cavern.

Upon seeing the video in a private screening, family members, who are living in a small village of tents at the entrance to the San José copper-gold mine—which they have named Camp Hope—were elated. “He’s skinny, bearded and it was painful to see him with his head hanging down, but I am so happy to see him alive”, said Ruth Contreras, the mother of Carlos Bravo, who is trapped in the mine. The video, of which only a small portion has been released to the public, shows the miners, many of them wearing helmets, cracking jokes and thanking the rescuers for their continued efforts. The supplies are being sent to the men through a small shaft only twelve centimeters wide, and a laboratory has been set up with the purpose of designing collapsible cots and miniature sandwiches, which can be sent down such a narrow space.

CNN reported on Friday that “officials are splitting the men into two shifts so one group sleeps while the other works or has leisure time .. On average, each man has lost 22 pounds (10 kilograms) since they became trapped three weeks ago, and dehydration remains a threat. But a survey of the men indicates that at least nine miners are still too overweight to fit through the proposed rescue shaft. Initially, the miners survived by draining water from a water-cooled piece of equipment. To stay hydrated in the 90-degree mine, each miner must drink eight or nine pints of water per day.”

But while there are jubilant celebrations on the surface that the miners are alive, officials are now nervous that the miners could become depressed, trapped in a dark room the size of a small apartment. Chilean health minister Jaime Mañalich said that, on the video, he saw the telltale signs of depression. “They are more isolated, they don’t want to be on the screen, they are not eating well”, he said. “I would say depression is the correct word.” He said that doctors who had watched the video had observed the men suffering from “severe dermatological problems.” Dr. Rodrigo Figueroa, head of the trauma, stress and disaster unit at the Catholic University in Santiago, Chile, explained that “following the euphoria of being discovered, the normal psychological reaction would be for the men to collapse in a combination of fatigue and stress … People who are trained for emergencies – like these miners – tend to minimize their own needs or to ignore them. When it is time to ask for help, they don’t.” NASA has advised emergency workers that entertaining the miners would be a good idea. They are to be sent a television system complete with taped football matches. Another dilemma facing Mañalich is whether the miners should be permitted to smoke underground. While nicotine gum has been delivered to the miners, sending down cigarettes is a plan that has not been ruled out.

With the news that drilling of the main rescue tunnel was expected to begin on Monday, officials have informed the media that they hope to have the miners out of the mine by Christmas—but sources with access to technical meetings have suggested that the miners could actually be rescued by the first week of November. A news report described the rescue plan—”the main focus is a machine that bores straight down to 688m and creates a chimney-type duct that could be used to haul the miners out one by one in a rescue basket. A second drilling operation will attempt to intercept a mining tunnel at a depth of roughly 350m. The miners would then have to make their way through several miles of dark, muddy tunnels and meet the rescue drill at roughly the halfway point of their current depth of 688m.” Iván Viveros Aranas, a Chilean policeman working at Camp Hope, told reporters that Chile “has shown a unity regardless of religion or social class. You see people arriving here just to volunteer, they have no relation at all to these families.”

But over the weekend, The New York Times reported that the “miners who have astonished the world with their discipline a half-mile underground will have to aid their own escape — clearing 3,000 to 4,000 tons of rock that will fall as the rescue hole is drilled, the engineer in charge of drilling said Sunday … The work will require about a half-dozen men working in shifts 24 hours a day.” Andrés Sougarret, a senior engineer involved in operating the drill said that “the miners are going to have to take out all that material as it falls.”

The families of those trapped were allowed to speak to them by radio-telephone on Sunday—a possibility that brought reassurance both the miners and those on the surface. The Intendant of the Atacama Region, Ximena Matas, said that there had been “moments of great emotion.” She continued to say that the families “listened with great interest and they both felt and realized that the men are well. This has been a very important moment, which no doubt strengthens their [the miners’] morale.” The phone line is thought to be quite temperamental, but it is hoped that soon, those in the mine and those in Camp Hope will be able to talk every day. “To hear his voice was a balm to my heart … He is aware that the rescue is not going to happen today, that it will take some time. He asked us to stay calm as everything is going to be OK … He sounded relaxed and since it was so short I didn’t manage to ask anything. Twenty seconds was nothing”, said said Jessica Cortés, who spoke to her husband Víctor Zamora, who was not even a miner, but a vehicle mechanic. “He went in that day because a vehicle had broken down inside the mine … At first they told us he had been crushed [to death].”

Esteban Rojas sent up a letter from inside the mine, proposing to his long-time partner Jessica Yáñez, 43. While they have officially been married for 25 years, their wedding was a civil service—but Rojas has now promised to have a church ceremony which is customary in Chile. “Please keep praying that we get out of this alive. And when I do get out, we will buy a dress and get married,” the letter read. Yáñez told a newspaper that she thought he was never going to ask her. “We have talked about it before, but he never asked me … He knows that however long it takes, I’ll wait for him, because with him I’ve been through good and bad.”

Brazilian astronomers have proposed a new model to explain the structure of our galaxy, the Milky Way. The new model suggests that our galaxy may have one more arm than previously thought and that these arms are more straight than curved.

The astronomers, led by Jacques Lepine at the University of Sao Paulo, used data from clouds of gas to develop their new proposed model.

In order to study the structure of the Milky Way, the astronomers studied spectra created by Carbon monosulphide clouds, contrary to the common method of analyzing spectra from clouds of ionized hydrogen. This method was used in hopes of producing an accurate ‘face-on’ map of our galaxy.

The postulated extra arm, if indeed actual, will increase the number of known arms from two to three. Previously, in 2008, the number was changed from four to two. This new arm is estimated to be about 30,000 light-years from the center of the Milky Way and is thought to have a “strong inward curvature”.

The new model also suggests that our Solar System is in one of the straightest parts of an outer arm of our galaxy.
