The University of Chicago’s Joe and Rika Mansueto Library was shut down by a power outage for a short time on Saturday, preventing library personnel from providing full services to its patrons.

The US$81 million library, which opened May 16, includes a 180-seat reading room under a 691-panel glass dome. Five stories underground, a system of five cranes retrieves books sorted into bins, carrying a maximum of about 3.5 million volumes. As of 3:50 p.m. CDT, the automated storage and retrieval system, along with staff computers at the circulation desk, were shut down, preventing patrons from retrieving materials stored underground.

The glass ceiling normally allows enough natural light to pass, but rain clouds in the area darkened the room. Patrons began to flip light switches in front of their seats, but to no avail, and a circulation clerk announced that there had been a power outage. Some patrons then moved to the adjacent Regenstein Library, which still had power. Power was still running along the corridor linking Mansueto and Regenstein Libraries, along with the nearby restrooms and Special Collections Research Center.

An electrician arrived at the building at around 3:50 p.m., and power had been restored by 5:45 p.m.

On Wednesday, English football club Chelsea FC announced signing French forward Olivier Giroud from cross-town rivals Arsenal FC on a eighteen-month contract. The deal is reportedly worth about £18 million. Olivier Giroud is to wear jersey number 18, the club announced via their website.

31-year-old Giroud joined The Gunners in 2012. Since then, the Frenchman has played 253 games for Arsenal and scored 105 goals. During his tenure at the Emirates Stadium, Giroud has won three FA Cups. He has also won the Community Shield trophy with Arsenal.

Giroud remarked on joining The Blues, “Chelsea is one of the biggest teams in the Premier League. They have won maybe the most trophies in the last six or seven years. It’s a massive club and I am proud to sign for Chelsea, and I’m looking forward to playing.”

Chelsea loaned Belgian forward Michy Batshuayi to German club Borussia Dortmund. Giroud’s departure from Arsenal was announced shortly after Arsenal announced signing Gabonese striker Pierre-Emerick Aubameyang from Dortmund for about £56 million making him the costliest player in Arsenal’s history.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

Sweden’s first royal wedding since 1976 took place Saturday when Crown Princess Victoria, 32, married her long-time boyfriend and former personal trainer, Daniel Westling, 36. The ceremony took place at Stockholm Cathedral.

Over 1,200 guests, including many rulers, politicians, royals and other dignitaries from across the world, attended the wedding, which cost an estimated 20 million Swedish kronor. Victoria wore a wedding dress with five-metre long train designed by Pär Engsheden. She wore the same crown that her mother, Queen Silvia, wore on her wedding day 34 years previously, also on June 19. Victoria’s father, King Carl XVI Gustaf, walked Victoria down the aisle, which was deemed untraditional by many. In Sweden, the bride and groom usually walk down the aisle together, emphasising the country’s views on equality. Victoria met with Daniel half-way to the altar, where they exchanged brief kisses, and, to the sounds of the wedding march, made their way to the the silver altar. She was followed by ten bridesmaids. The couple both had tears in their eyes as they said their vows, and apart from fumbling when they exchanged rings, the ceremony went smoothly.

Following the ceremony, the couple headed a fast-paced procession through central Stockholm on a horse-drawn carriage, flanked by police and security. Up to 500,000 people are thought to have lined the streets. They then boarded the Vasaorden, the same royal barge Victoria’s parents used in their wedding, and traveled through Stockholm’s waters, accompanied by flyover of 18 fighter jets near the end of the procession. A wedding banquet followed in the in the Hall of State of the Royal Palace.

Controversy has surrounded the engagement and wedding between the Crown Princess and Westling, a “commoner”. Victoria met Westling as she was recovering from bulemia in 2002. He owned a chain of gymnasiums and was brought in to help bring Victoria back to full health. Westling was raised in a middle-class family in Ockelbo, in central Sweden. His father managed a social services centre, and his mother worked in a post office. When the relationship was made public, Westling was mocked as an outsider and the king was reportedly horrified at the thought of his daughter marrying a “commoner”, even though he did so when he married Silvia. Last year, Westling underwent transplant surgery for a congenital kidney disorder. The Swedish public have been assured that he will be able to have children and that his illness will not be passed on to his offspring.

Westling underwent years of training to prepare for his new role in the royal family, including lessons in etiquette, elocution, and multi-lingual small talk; and a makeover that saw his hair being cropped short, and his plain-looking glasses and clothes being replaced by designer-wear.

Upon marrying the Crown Princess, Westling took his wife’s ducal title and is granted the style “His Royal Highness”. He is now known as HRH Prince Daniel, Duke of Västergötland. He also has his own coat-of-arms and monogram. When Victoria assumes the throne and becomes Queen, Daniel will not become King, but assume a supportive role, similar to that of Prince Phillip, the husband of the United Kingdom’s Queen Elizabeth II.
