Uffizi art collections to showcase in Shanghai in 2022******

SHANGHAI, Nov. 8 (Xinhua) -- The world-renowned Italian art museum, La Galleria degli Uffizi, teamed up with the Bund One Art Museum to hold a series of the top art exhibitions in Shanghai starting from April 2022.。

A total of 10 exhibitions are scheduled in Shanghai in the next five years, the two parties announced on Nov. 6. Two of the serial exhibitions will be dedicated to celebrating the China-Italy Year of Culture and Tourism in 2022.。

The collaboration is expected to be the very first time the art collections preserved by the Italian gallery are showcased on such a large scale in China.。

In April 2022, the first three exhibitions will be held in Shanghai, covering masterpieces from the Renaissance period and artworks created between the 16th and 21st centuries.。

Based in Florence of Italy, the Uffizi Gallery is well-known worldwide for its ancient sculptures and collections of paintings, while the Bund One Art Museum is one of Shanghai's emerging landmarks. Enditem。

NASA's new space telescope reaches destination in solar orbit******

NASA's James Webb Space Telescope, designed to give the world an unprecedented glimpse of infant galaxies in the early stages of the universe, arrived at its gravitational parking spot in orbit around the sun on Monday, nearly a million miles from Earth.

With a final five-minute, course-correcting thrust of its onboard rocket, Webb reached its destination at a position of gravitational equilibrium known as the second Sun-Earth Lagrange point, or L2, one month after launch.

The thruster was activated by mission control engineers at the Space Telescope Science Institute in Baltimore, with radio signals confirming Webb was successfully "inserted" into its desired orbital loop around L2.

Webb will follow a special "halo" path that keeps it in constant alignment with Earth but out of its shadow, as the planet and telescope circle the sun in tandem. The L2 orbit within the larger solar orbit enables uninterrupted radio contact, while bathing Webb's solar-power array in non-stop sunlight.

Minimizing drift

By comparison, Webb's 30-year-old predecessor, the Hubble Space Telescope, orbits the Earth 547 kilometers away, passing in and out of the planet's shadow every 90 minutes.

The combined pull of the sun and Earth at L2 – a point of near gravitational stability first deduced by 18-century mathematician Joseph-Louis Legrange – will minimize the telescope's drift.

But ground teams will need to fire Webb's thruster briefly again about once every three weeks to keep it on track, Keith Parrish, the observatory's commissioning manager from NASA's Goddard Space Flight Center said.

Mission engineers are preparing next to fine-tune the telescope's primary mirror – 18 hexagonal segments of gold-coated beryllium metal measuring 6.5 meters across, far larger than Hubble's main mirror.

Beijing 2022 ignites winter sports passion in east China******

NANJING, Dec. 13 (Xinhua) -- As the Beijing 2022 Winter Olympics draws closer, winter sports are becoming increasingly popular in east China's Jiangsu Province, where 45 winter sports venues have been built, with a total of 553,200 square meters.。

As one of the largest winter sports arenas, the skating rink in the Nanjing Olympic Stadium has seen a distinct increase in visitors in recent years. "The guests here have increased by about 30 percent annually from the year of 2018," said Yuan Jun, the man in charge of the ice sports club in the stadium.。

Statistics show that the ice sports club in the stadium now receives about 50,000 amateurs and 40,000 trainees every year, with 400 visitors on average each day during the weekend.。

Winter sports venues like the Nanjing Olympic Stadium have been springing up these years in Jiangsu, covering all the 13 cities in the province. Cities like Xuzhou, Changzhou and Huaian even built ski resorts in scenic spots.。

To inspire people's passion for winter sports, Jiangsu has issued winter sports consumer vouchers for four consecutive years. Nearly five million yuan (about 786,000 thousand U.S. dollars) consumer vouchers have been issued this year.。

The province also invited national-level winter sports coaches to attract young amateurs. Guan Weinan, a retired ice hockey national player, has helped the city of Nanjing establish an ice hockey team that won the silver medal in the national competition in 2019. Enditem。
