Reach for the stars at the Euro Space Center. Find out everything you need to know about space — from the origins (起源) of the universe to the future space exploration plans. Light, sound and special effects help to bring your space journey to life. Throughout your tour, our specially trained guides will answer your questions and provide you with any information you require.

    Begin your tour with our exhibition about the planets, then move on to the Space Laboratory and see some of the experiments carried out in space. Visit our international space station, where you can climb into our full-scale Space Shuttle model and experience life on board as an astronaut.

    You will know all about space by now and to help you further, our Space Center astronaut will tell you about how young people train as astronauts in our own training school. Finally, you can watch our amazing Space Show in our IMAX cinema, which will help you understand everything you have learned during your visit better.

    Outside we have an outdoor exhibition including a giant solar system, full-size rocket models and outdoor games. Don't worry if it rains — much of this is under cover.

    After that, why not visit our restaurant Resto Space for food and drink on a space theme? And don't forget our Space Shop, offering you a lot of gifts to take home.

    The Euro Space Center is open every day during school holidays, and also during other times except Mondays. Opening times are 10:00-5:00. For entrance fees, call our booking service on + 32-61-650133. Or you can email us for up-to-date entry information at info@eurospacecenter.be.

    Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.

     “ I'd use it if I were hanging out with friends at 3 a. m. and going to the [bar and wanted to see what was open,” said Walter Choo, 40, of Fort Greene.

      The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented(增强的) reality, a technology already available on smartphones and tablets (平板电脑) that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would pop up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.

     “ As far as a mainstream consumer product, this just isn't something anybody needs,” said Sam Biddle, who writes for Gizmodo.com.  “ We're accustomed to having one thing in our pocket to do all these things,” he added, “and the average consumer isn't gonna be able to afford another device (装置) that's hundreds and hundreds of dollars.”

    9to5Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones.

     “It's just like smartphones 10 years ago,” Weintraub said. “A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural,” he said. “ There's gonna be improvements to that, and this a step there.”

    A new web standard is expected to kill passwords, meaning users will no longer have to remember difficult logins(登录) for each and every website or service they use.

    The Web Authentication (WebAuthn网络认证) standard is designed to replace the password with tools that users already own, such as a security key, a smart phone, a fingerprint scanner or webcam. Instead of having to remember long characters, users can authenticate their login with their body or something they have, communicating directly with the website through Bluetooth, USB or NFC.

    "WebAuthn will change the way that people access the Web," said Jeff Jaffe, CEO of the World Wide Web Consortium (W3C), the body that controls web standards. One example of how WebAuthn will work is that when a user visits a site, they put in a user name and then get a message on their smart phone. Tapping on the message on their phone then logs them into the website without the need for a password.

    WebAuthn promises to protect users against phishing attacks(钓鱼攻击) and the use of stolen information as there will be nothing to steal, the authentication sign is produced and used once by their special tool each time the user enters.

    "After years of increasingly serious data and password being stolen, now it is the time for service providers to end their dependency on easily-attacked passwords and use phishing-resistant FIDO Authentication(快速身份认证联盟) for all websites and apps," said Brett McDowell, CEO of the FIDO Alliance, one of the bodies pushing the new standard.

    WebAuthn should also help people use special login details for each and every service they use, instead of using the same login and password for every site, which many people still do, leaving them further attacked if one site is hacked(黑客攻击).

    The W3C has moved WebAuthn to what's called the "candidate recommendation" stage – the last-but-one step before it becomes an approved web standard – inviting sites and services to begin using it. The web standards body announced that Google, Microsoft and Mozilla had been devoted to supporting WebAuthn, meaning that all major web explorers except Apple's Safari will use the new standard.

    "While there are many web security problems and we can't fix them all, relying on passwords is one of the weakest links. With WebAuthn's solutions we are removing this weak link," said Jaffe.

    Several sites and services already use similar methods to enter, including Google and Facebook, which can both be entered using a USB security key. But a single cross-platform, cross-service standard approved by the W3C will mean that many more sites and services will be able to kill the password as the login method.

    WebAuthn is the top of many years of work and the change will not happen overnight. But as it increasingly seems unavoidably that our email or other online services will get hacked into, removing the password is an important step in improving online security and making using sites and services easier.

    Audrey Hepburn won an Academy Award as Best Actress for her first major American movie，Roman Holiday，which was released in 1953．But she is remembered as much for her aid work as for her acting．

    Born in Belgium in 1929，Audrey's father was British and her mother was Dutch．Audrey was sent to live at a British school for part of her childhood．During World War II，she lived and studied in the Netherlands. Her mother thought it would be safe from German attacks．Audrey studied dance as a teenager and during college when she returned to London after the war．But she realized she wasn't going to be a ballerina （芭蕾舞女演员）．So she began taking acting parts in stage shows．Later she began to get small parts in movies．

    But it was Audrey Hepburn's move to America that brought her true fame．In 1951 she played the character"Gigi"in the Broadway play of the same name to great critical praise．Two years later，Roman Holiday made her a star at the age of 24．

    Audrey made more than 25movies．Among her most popular roles was Holly Golightly in Breakfast at Tifany's in 1961．Three years later she played Eliza Doolittle in My Fair Lady．

    She was married two times and had one son by each husband．In 1989，the UN Children's Fund named Audrey a goodwill ambassador．She travelled all over the world in support of UNICEF （联合国儿童基金会） projects．The UN agency said she was a tireless worker．She often gave 15interviews a day to gain money and support for UNICEF projects．

    Audrey Hepburn often said her loyalty to UNICEF was the result of her experiences as a child during World War II．She said she knew what it was like to be starving and to be saved by international aid．She was a goodwill ambassador until her death in 1993from colon cancer．

    Nearly everyone has bad habits. That's because, try as we might, bad habits are hard to break. On the other side, good habits, such as eating more healthfully or exercising regularly, never seem to stick. As a result, most people throw up their hands and surrender.

    But now a new book, Better Than Before: Mastering the Habits of Our Everyday Lives by best-selling author Gretchen Rubin, offers some useful solutions.

    Rubin, who became interested in habits during her research on happiness, which resulted in two popular books, The Happiness Project (2009) and Happier at Home (2012), found that our inability to master unwanted behaviors was a major downer (令人沮丧的因素). So, after guiding millions of readers down the path of true contentedness, Rubin turned her investigative skills toward habits.

    Her most important find? Change is possible if we do some soul searching and identify how we respond to expectations. And, just about everybody falls into one of four personality categories: Questioners, Obligers, Rebels and Upholders.

    Rubin believes herself to be a classic Upholder, someone who forms habits relatively easily because she responds well to both other people's deadlines and her own. As to the other types, Questioners will only form a habit if it makes sense to them; Obligers work hard to meet other people's expectations but often let themselves down. And Rebels resent (反感) habits.

    "Think about the habit that you want to form and then think: "What's everything I could do to set myself up for success?" says Rubin. For example, if you want to exercise more and you're an Obliger, call your friend who lives across the street and meet at 6：30 every morning for a walk.

    One common pitfall (陷阱), says Rubin, especially when it comes to changing your diet, is lack of clarity (清楚). "You can't make a habit out of eating more healthfully, "she says. Instead, your habit should be something like: "I'm going to pack a lunch every day and bring it to work instead of eating out."

    As for exercise, Rubin recommends a strategy called pairing—coupling two activities, one that you need or want to do and one that you don't particularly want to do. Rubin, for example, only allows herself to read magazines while on fitness equipment at the gym.

    We hope you've finally made your peace with Pluto being downgraded from a planet to an ice dwarf (冰矮星)，because we have some more jarring news for you : It seems your teachers may have been wrong about the number of continents on the earth, too.

    Earlier this year, scientists published a report in the journal of the Geological Society of America detailing an eighth continent called Zealandia, roughly the size of India and almost completely hid itself under the Pacific Ocean east of Australia. Covering all of New Zealand as well as several nearby islands, Zealandia likely spent the best of its above-water days as part of the supercontinent Gondwana before fragmenting off Australia and Antarctica some 80 million years ago. This lost, underwater continent is just beginning to reveal its secrets, making for one of the most promising scientific discoveries this year.

    While researchers have been aware of the 1. 9 million-square-mile mass for two decades, Zealandia has only recently become the object of serious study since the Geological Society paper argued that it fits all the criteria for a proper continent, including a continental crust (地壳)that's distinctly separate from the seabed in terms of elevation, thickness, and geology. A team of 32 scientists from 12 countries just completed their first visit to six dig sites around Zealandia, where they drilled up more than 8,000 feet of sediment cores (沉积物岩心)that will help explain the lost continent's 80-million-year history.

    Because there is no official body that formally recognizes continents, whether or not Zealandia ends up in future geography textbooks will come down to its acceptance by the scientific community at large, possibly with a little help from travelers like you.
