This year is the 70th anniversary of the Aspen Music Festival, one of the longest-running and most prestigious festivals in the United States. The 2019 program has yet to be announced, but a typical eight- week summer season includes more than 400 classical music events—including concerts by five orchestras, solo (独奏) and classical music performances, fully staged opera productions, music lessons, lectures, and children’s programming.

Grand Teton Music Festival

Aspen’s great classical music competitor in the Rocky Mountains is the Grand Teton, which has been held in Jackson Hole since 1962 and at its heart is a timber concert hall, the Walk Festival Hall, famous for its friendly atmosphere and excellent natural sound. Despite its relatively modest size, the hall attracts the greats—current music director is the Scottish conductor Donald Runnicles. The program for 2019 is yet to be announced but subscriptions are on sale from Feb 1, single tickets from March 1.

Mark Elliot Zuckerberg was born on May the 14th, 1984. He is the creator of the social media site Facebook. He was a star student at school, winning prizes in astronomy, maths and physics. He was also good at Classical studies. He studied Psychology and Computer Science at Harvard University, which is where he created Facebook. His invention led to his becoming Time magazine’s Person Of The Year for 2010.

Zuckerberg excelled in everything he did in his youth. He was captain of the school fencing team, spoke many languages and was a highly skilled computer programmer. While other kids played computer games, he designed them. He created his first network while in high school to connect all of the computers - in his father’s dental surgery. He also built a media player which attracted the interest of Microsoft and AOL.

Zuckerberg started at Harvard in September 2002. In his first year, he created Facemash, a Facebook predecessor (前身), which let students select the college’s best looking people from a selection of photos.

He launched Facebook from his Harvard room in February 2004. It was the start of a rollercoaster ride that would connect half a billion people worldwide and make him the world’s youngest billionaire.

Mark Zuckerberg is now one of the most influential people on the planet. He has dined with the president of the USA and regularly attends global economic summits and technology conferences. He stated: “The thing I really care about is the mission, making the world open.” In 2010, Zuckerberg signed a promise, in which he promised to donate at least half of his life wealth to charity.

China has become the first country to successfully land a spacecraft on the far side of the moon. The Chang’e-4 probe (探测器) has also made the first lunar landing since 1972. It has the task of exploring the side of the moon that never faces the earth. The dark side of the moon is older and has a thicker surface than the visible side. It takes the moon as long to go around on its own axis (轴) as it does for one complete orbit around the Earth.

The Chinese probe landed in a huge crater 2500 km in diameter and 13 km deep. The crater is one of the oldest parts of the moon and our solar system.

Scientists hope to learn more about the geology of the far side of the moon. The craft has two cameras on board which will send images back to earth. It will also attempt to send signals to distant regions of space, something that cannot happen on earth because of too much radio noise.

Chang'e-4 also has instruments on board to examine minerals as well as a container with seeds which will try to create a miniature (微型的) biosphere (生物圈).

Communication with the spacecraft is not easy. Images and other data must be transmitted to a separate satellite because no direct communication with the earth is possible.

For China the Chang'e-4 mission is an important achievement, because the country has successfully done something no other nation on earth has. It wants to become a leading power in space exploration and has announced plans to send astronauts to the moon and set up its own space station.

As the weather gets colder, we start wearing jackets, and most of us stop thinking about the sun. But the sun’s rays can be just as harmful when it’s cold and cloudy outside. “Any exposed area of your body can still get sunburned,” Dr. Apple Bodemer, an associate professor at the University of Wisconsin-Madison, told Live Science.

Whether you spend a day on the slopes, skating on a pond or clearing snow out of your driveway, your face is still getting exposed to the sun’s radiation in the form of ultraviolet (紫外线) (UV) light, which can go deep into your skin cells causing DNA damage, according to Bodemer.

The sun’s long ultraviolet A (UVA) waves can cause earlier aging, sunspots and wrinkles, while its short ultraviolet B (UVB) rays are known for causing skin reddening and burns.

Skin damage caused by UV exposure increases over time. More exposure to radiation contributes to more severe damage, even skin cancer. In addition, snow and ice can also make sun damage worse. They reflect up to 80 percent of UV rays reaching the ground. That means you get hit from both the sky and the ground. And skiers and snowboarders increase their risk of getting sunburned even more because UV exposure increases at higher altitudes.

“Generally, the biggest factor for sun-sensitivity is how pale your skin is,” he said. “But, the reality is that even the darkest individual can get sun damage.”

Luckily, the solution for protecting your skin is simple: Wear sunscreen every day. Rigel recommended using sunscreen with a sun protection factor (SPF) of at least 30, and going higher at high altitudes. As a rule of thumb, SPF 30 will block 97 percent of UVB rays, SPF 50 blocking 98 percent, and SPF 100 blocking 99 percent. Whatever kind of sunscreen you use, it’s important to apply SPF about once every 2 hours.

Rigel also suggested sunscreens with “broad spectrum (光谱)”—to protect against both UVB and UVA rays—as well as sunscreens that are water resistant for up to 80 minutes. That way, you can go about your day without it wearing off too quickly.
