Launched in 1956, Eurovision is a Europe-wide music competition held every May under the auspices of the European Broadcasting Union (EBU). Participating countries select their representative songs over the course of the preceding winter and spring. Some countries – like Sweden – make their selections via televised heats held over several consecutive weeks. Others – like the U.K. (this year, at least) – make their selections by internal committee.

Eurovision is a major event in Europe, with a remarkable 125 million viewers.

Nowadays, Eurovision lasts for almost an entire week. With the end of the Cold War and the dissolution of the Soviet Union, there are now so many participating countries – 39 this year; even more in recent years – that two semi-finals are required to winnow down contestants to a manageable tally for the grand final. After semifinals on Tuesday and Thursday, this year's final will be held later today in Malmö, Sweden. (Sweden won Eurovision last year, and with its win came the right to host this year's contest.)

Budget traveling night owl alert: if you're in Europe right now you don't want to miss out on the ninth annual European Night of Museums this Saturday, May 18.

The idea is simple: open up museums way past their general closing hours, cut the entrance fee and make museum going a little more like nightlife instead of a rainy Sunday afternoon activity.

Coinciding with International Museum Day, European Night of Museums is organized by the French Ministry of Culture and Communication, and this year almost 3,000 museums around Europe are participating not just by opening their doors for the late-night crowd, but hosting special events and beyond. Track them down here.

In Paris for example you have access to 150 museums and cultural centers - most of them for free - and while the waived entrance fee might attract a larger crowd to some of the more well known spots, it also means the chance to explore a few new places that you might have been meaning to check off the list.

In the U.K., you'll also find Museums at Night, tied in with the European Night of Museums campaign, but open for a couple of extra days, this year held May 16-18, 2013.

Latvia, Romania, Norway ... wherever you are in Europe, find a museum and book your Saturday night.

It has been a long and wild climbing season on the world's tallest mountain. Over the past few years, Mt. Everest has been widely criticized for being an over crowded stage for publicity seekers and tourist climbers who have no business being on the mountain. That hasn't changed much this spring, but when you add in the recent brawl between three European climbers and a mob of angry Sherpas, not to mention the death of a very well known Russian mountaineer earlier this week, the 2013 season has been a strange and difficult one indeed. But for most of the climbers, the end is now in sight. After nearly two months away from home and weeks of acclimatizing at altitude, all of their preparation is about to pay off. Summit Day has arrived at last.

The summit of Everest has remained an elusive place thus far this spring. A week ago two teams of Sherpas completed the job of fixing the ropes to the top of the mountain from both the North Side in Tibet and the South Side in Nepal. A couple of daring and experienced climbers followed closely behind and were able to top out just before a system of bad weather moved in. Since then, high winds have kept the summit out of reach and challenged the patience of the other teams waiting to make their ascents. Over the past few days, a number of those teams attempted to reach the top, but most of them were turned back by persistent bad weather. Today the skies cleared, the winds have calmed and temperatures have even warmed a bit making it a perfect day to climb to the top.

Just past the eastern terminus of the Tioga Pass, the entryway to Yosemite National Park, is the quietly beautiful Mono Lake. The area is unique due to its salinity and eerie tufa rock formations that jut out from the water, which give it a completely unreal appearance. Flickr user Pacheco took this amazing photo of the moonrise after a two-day mission to get the perfect Mono lake photo. He absolutely succeeded.

The surrounding area is fantastic as well because it has these little roads that stretch on into the mountains that are perfect to drive on and are often empty of anyone else. California is not often associated with its mountainous landscapes, but in large part thanks to it huge size, it has some of the best natural beauty in the United States.

To International travelers, the name Travelex should sound familiar. They are the largest airport currency exchange operator in the world. But a recent currency exchange study comparing the cost of using Travelex, some of the largest U.S. banks and credit cards revealed what experts already knew.

CardHub's 2013 Currency Exchange Study compared the cost of the currency exchange services offered by 15 of the largest banks in the U.S. as well as Visa, MasterCard and Travelex. The study proved that using a no foreign fee credit card is the way to go on spending internationally. Banks charge an average of exchange rate of 7.1% and Travelex charges 15.5%.

Worried about using a credit card outside of the U.S.? Don't be. Credit cards also provide fraud protection for just that reason.

"Even if a consumer uses a credit card with foreign fees – the average foreign transaction fee is 2.24%, according to CardHub's latest Credit Card Landscape Report – he'll still save 4.86% on currency conversion relative to the services offered by banks and 13.26% compared to airport currency exchange providers," said CardHub CEO Odysseas Papadimitriou in a HeraldOnline report.

The best banks for currency conversion? The CardHub study indicates Northern Trust and Harris Bank lead the pack as they did in the 2012 and 2011 editions of the study while U.S. Bank and SunTrust hold the bottom two spots. On average though, banks are better than Travelex, saving an average 8.4%.

Archaeologists excavating at Lincoln Castle have discovered the remains of an early Christian community, according to a Lincolnshire County Council press release.

The team, which was digging inside the castle to clear the way for an elevator shaft, found the remains of a church that dates back at least 1,000 years. Inside a sealed niche in the wall they found human bones. They had been wrapped in finely woven cloth and while the cloth has long since disappeared, it left its impression on the surrounding mortar. Excavators theorize that these may be the remains of a holy person, as it was common to put relics in church walls and altars in order to make them holy.

An even older find included several skeletons and a stone sarcophagus. The archaeological team is planning to put an endoscopic camera into the coffin to see what's inside without disturbing it.

Seven months after Hurricane Sandy ravaged New York City-area beaches, construction will begin on replacement pavilions for those that were destroyed in the storm. Here's a peek at what destinations like Rockaway Beach and Coney Island will look like, courtesy of Garrison Architects, the firm that was asked to create these modular pavilions.

Structures include bathrooms for the public, stands for lifeguards and offices for beach staff, all of which sit on concrete stilts in order to meet standards put in place by the Federal Emergency Management Agency (FEMA). According to architecture blog Architizer, the materials used to produce the pavilions, like galvanized steel frames, will ensure the structures resist severe weather in the future. The pavilions also have double-ventilated roofs with solar panels on top to save on energy consumption.

According to the architects, the pavilions will be built in Pennsylvania and then transferred via flatbed trucks to New York, where cranes will set them on pile foundations. Ramps and stairs will connect the structures to each other and provide access to the beaches and boardwalks. The new facilities should be put in place just in time for summer.

If your frequent flier miles are languishing unused in your account because you keep coming up against blackout dates whenever you try to use them, then perhaps it's time to switch airlines, or maybe even rethink your booking tactics.

A survey by IdeaWorksCompany looked at 25 of the biggest frequent flier programs to figure out which carriers were best when it came to redeeming frequent flier points. The study checked each of the airline's primary routes to see what level of availability there was for travelers looking to book a flight using their miles.

In what would otherwise make for a great comedy sketch, an Air India captain took a bathroom break during a flight Tuesday night and returned to find a jammed cockpit door. But according to a report by USA Today, this was no laughing matter: after all efforts failed to open the door - even from the inside - the co-pilot landed the plane at the nearest airport, where ground maintenance staff fixed the problem. The plane then resumed its flight, which was making its way from New Delhi to Bangalore.

This is the second strange cockpit incident that's happened with Air India recently; earlier this month, pilots allowed flight attendants to sit in their chairs while they napped, and one of the attendants accidently disengaged the plane's autopilot function. In both instances, no passengers were injured.

Does the mere thought of street food set your stomach to rumbling? If so, you'll want to get yourself to Singapore– the world's unofficial street food (or, technically, hawker centre)– capital. The city is hosting the World Streetfood Congress May 31-June 9. Don't let the stern-sounding name fool you: this 10-day event is all about hedonism, snackie-style.

In addition to a World Streetfood Jamboree featuring the "best street food masters" from all over the world, there are also demos, a first-of-its-kind awards ceremony, discussions on "street food opportunities," live music, and more.

For those in the F & B industry, a two-day conference, The World Street Food Dialogues, will be held June 3-4. It will feature noted speakers/street food experts such as Anthony Bourdain, Saveur magazine editor-in-chief James Oseland, Brett Burmeister, managing editor and co-owner of Food Carts Portland, and Singapore's beloved KF Seetoh, chef, food writer, and founder of the Makansutra food centre and "foodbooks." Makansutra is also the organizer of the World Streetfood Congress.
