= WASP @-@ 13b =
WASP @-@ 13b is an extrasolar planet that was discovered in 2008 in the orbit of the sunlike star WASP @-@ 13 . The planet has a mass of nearly half that of Jupiter , but a radius five @-@ fourths the size of Jupiter . This low relative mass might be caused by a core that is of low mass or that is not present at all ....
The planet orbits at approximately 5 % of the distance between the Sun and Earth every four days . The star was observed several times between 2006 and 2009 , at first through the SuperWASP program and later through focused follow @-@ up observations . Analysis of collected radial velocity measurements led to the disc...

Between November 27 , 2006 , and April 1 , 2007 , 3329 images of the star WASP @-@ 13 by the SuperWASP @-@ North program based at Roque de los Muchachos Observatory in the Canary Islands led to the identification of WASP @-@ 13 as host to a potentially transiting object . Photometric follow @-@ up observations were ta...
WASP @-@ 13 was observed between February 11 and 15 in 2008 by the SOPHIE échelle spectrograph at the Haute @-@ Provence Observatory in France , determining the radial velocity of the transiting body . Use of the FIES echelle spectrograph at the Nordic Optical Telescope in the Canary Islands gained other spectral meas...
The discovery of WASP @-@ 13b was reported in the journal Astronomy and Astrophysics by the European Southern Observatory on May 19 , 2009 . The discovery paper was received by the journal on April 7 , 2009 .
Later , between 2009 and 2011 , another team of astronomers observed WASP @-@ 13b and WASP @-@ 21b to find what caused some Hot Jupiters to have anomalously high radii . The RISE photometric camera on the Liverpool Telescope was used to detect further transits . Two partial transits and two full transits were observed...

= U2 concert in Sarajevo =
On 23 September 1997 , the Irish rock band U2 held a concert at Koševo Stadium in Sarajevo , Bosnia and Herzegovina , as part of the group 's PopMart Tour . They were the first major artist to hold a concert in the city after the end of the Bosnian War . Approximately 45 @,@ 000 fans attended the show .
The band first became involved with Sarajevo in 1993 on their Zoo TV Tour ; approached by aid worker Bill Carter about bringing attention to the Siege of Sarajevo , the band conducted nightly satellite transmissions with Bosnians during their shows . These link @-@ ups were the subject of criticism from journalists fo...
The band offered to hold a benefit concert or small show in Sarajevo , but it was requested that they stage a full PopMart concert . The performance consequently featured the tour 's extravagant stage , and the band played a set list typical of the tour . The show brought together people of different ethnicities who h...

In 1993 , U2 were in Europe for the " Zooropa " leg of their Zoo TV Tour . Before their 3 July show in Verona , Italy , the band received a fax from Radio Televizija Bosne I Hercegovina asking for an interview regarding the situation in Bosnia . The band agreed and met with an American aid worker named Bill Carter , w...
Bono agreed to Carter 's request without asking the rest of the band , and when informed of the idea , the other members gave only tacit approval . They briefly considered playing an impromptu concert in the city , with Bono suggesting that they perform in the bunker where Carter and his friends hid during the siege ....
Instead , the group agreed to use the tour 's satellite dish to conduct live video transmissions from their concerts to Carter in Sarajevo . Carter returned to the city and assembled a video unit . The band purchased a satellite dish to be sent to Sarajevo and paid a £ 100 @,@ 000 fee to join the European Broadcasting...
Reactions to the transmissions were mixed . Many fans felt the transmissions disrupted the flow of the concerts . Most of the British press was highly critical . One writer for NME wrote , " The Bosnian linkup was beyond bad taste . It was insulting . " Bono thought that they were bringing the public 's attention to a...
The band contributed to Bosnian relief efforts to enhance humanitarian and public awareness of the issue , and Bono and Carter subsequently collaborated on the documentary Miss Sarajevo , which showcased the war @-@ torn city during Carter 's six months living there . In 1995 , U2 and Eno wrote the song " Miss Sarajev...

As the Bosnian War ended in 1995 and the Siege of Sarajevo in 1996 , the stability of the region began to improve . Realizing this , U2 began to plan a concert for Sarajevo that would take place on their 1997 PopMart Tour . Although they were the first major musical artist to perform in the city following the war , Ch...
Scheduling the concert meant a financial loss of £ 500 @,@ 000 for the band , despite sponsorship from Coca @-@ Cola and GSM . Ticket prices were set at just DM 8 ( £ 8 , US $ 18 ) , because of the 50 percent unemployment rate in the city . Bono offered for the group to perform a benefit concert or small show in Saraj...
As late as July 1997 , U2 were pressured to accept an offer of approximately $ 4 million to perform in Basel , Switzerland on the date scheduled for the Sarajevo show . At the time , rumours about the region 's instability persisted . To ensure the Sarajevo show was not canceled , Sacirbey appeared at many of the band...
Several hundred members of the international " Stabilisation Force " ( SFOR ) were tasked with upholding the Dayton Agreement for the concert . The band were overwhelmed by the sights they saw when arriving . During the war , Koševo Stadium was used as a morgue , and graveyards were present on either sides . Although ...
On the day of the concert , trains ran into Sarajevo for the first time since the start of the war . Two lines were opened , one from Mostar to Sarajevo and the other from Maglaj to Sarajevo . Although the railways had been functional for the duration of the war , Muslim and Croat politicians could not decide who woul...

Three opening acts played before U2 , beginning with the Gazi Huzrev @-@ Beg choir , an Islamic choir from a local high school . Their performance was followed by two local bands , Protest and Sikter , one of which was chosen personally by Sacirbey , and the other which was selected through a radio contest . Following...
The band 's set list was similar to that of most shows on the PopMart Tour , but with " Sunday Bloody Sunday " in place of The Edge 's karaoke segment and the addition of " Miss Sarajevo " in the second encore . The night was a celebration of the end of the war , with Bono setting the tone by shouting out " Viva Saraj...
At various points during " Until the End of the World " and " New Year 's Day " , Bono gestured for the audience to help him with the vocals , and by the eighth song of the night , " Pride ( In the Name of Love ) " , he was reduced to speaking the lyrics instead of singing them . The band continued with their standard...
In the interlude before the first encore , U2 had a worried discussion over the introduction to " Miss Sarajevo " . The song had only been played once prior — at a benefit concert in 1995 with Bono , The Edge , Eno , and Pavarotti . They returned to the stage and played " Discothèque " , " If You Wear That Velvet Dres...
After the band had walked offstage , in a move described by NME as the most meaningful of the concert , the audience faced the troops in the stadium and broke into a spontaneous round of applause , which quickly turned into an ovation — an act which the soldiers mimicked in turn .

The peaceful nature of the U2 concert was fleeting , as violence flared up in the region the following year with the Kosovo War . NATO troops remained in Sarajevo until 2004 , while European Union peace @-@ keeping troops remain in the city .
Following the Sarajevo concert , The Edge 's solo performance of " Sunday Bloody Sunday " was performed at the majority of shows for the remainder of the tour , and a recording of the song from the Sarajevo concert was released on the CD single for " If God Will Send His Angels " on 8 December 1997 ; The Edge later st...
After U2 first performed " Miss Sarajevo " at the Sarajevo concert , it was not performed again until the second leg of the Vertigo Tour in 2005 . U2 did not return to perform in any country in the former Yugoslavia until August 2009 , when they performed two shows in Zagreb during the U2 360 ° Tour . During the Zagre...
= Frank Slide =
The Frank Slide was a rockslide that buried part of the mining town of Frank , Alberta , Canada . The province of Alberta was not created until September 1905 , more than two years after the slide . The community was still part of the Northwest Territories when the incident occurred at 4 : 10 am on April 29 , 1903 . O...
The railway was repaired within three weeks and the mine was quickly reopened . The section of town closest to the mountain was relocated in 1911 amid fears that another slide was possible . The town 's population nearly doubled its pre @-@ slide population by 1906 , but dwindled after the mine closed permanently in 1...

The town of Frank was founded in the southwestern corner of the District of Alberta , a subdivision of the Northwest Territories in 1901 . A location was chosen near the base of Turtle Mountain in the Crowsnest Pass , where coal had been discovered one year earlier . It was named after Henry Frank who , along with Sam...
Turtle Mountain stands immediately south of Frank . It consists of an older limestone layer folded over on top of softer materials such as shale and sandstone . Erosion had left the mountain with a steep overhang of its limestone layer . It has long been unstable ; the Blackfoot and Kutenai peoples called it " the mou...

In the early morning hours of April 29 , 1903 , a freight train pulled out of the mine and was slowly making its way towards the townsite when the crew heard a deafening rumble behind them . The engineer instinctively set the throttle to full speed ahead and sped his train to safety across the bridge over the Crowsnes...
Initial reports on the disaster indicated that Frank had been " nearly wiped out " by the mountain 's collapse . It was thought the rockslide was triggered by an earthquake , volcanic eruption or explosion within the mine . The majority of the town survived , but the slide buried buildings on the eastern outskirts of ...
Approximately 100 people lived in the path of destruction , located between the CPR tracks and the river . The death toll is uncertain ; estimates range between 70 and 90 . It is the deadliest landslide in Canadian history and was the largest until the Hope Slide in 1965 . It is possible that the toll may have been hi...
Initial news reports stated that between 50 and 60 men were within the mountain and had been buried with no hope of survival . In reality , there were 20 miners working the night shift at the time of the disaster . Three had been outside the mine and were killed by the slide . The remaining 17 were underground . They ...
The miners found that the row of cottages that served as their homes had been devastated and some of their families killed , seemingly at random .

Early on April 30 a special train from Fort Macleod arrived with police officers and doctors . Premier Frederick Haultain arrived at the disaster site on May 1 , where he met with engineers who had investigated the top of Turtle Mountain .

Clearing the Canadian Pacific Railway line was of paramount importance . Approximately 2 kilometres ( 1 @.@ 2 mi ) of the main line had been buried under the slide , along with part of an auxiliary line . The CPR had the line cleared and rebuilt within three weeks . Intent on reopening the mine , workers opened passag...
The town 's population not only recovered but grew ; the 1906 census of the Canadian Prairies listed the population at 1 @,@ 178 . A new study commissioned by the Dominion government determined that the cracks in the mountain continued to grow and that the risk of another slide remained . Consequently , parts of Frank...
