Barcelona eyeing River Plate forward Alvarez******

BUENOS AIRES, Dec. 10 (Xinhua) -- Barcelona have joined the race to sign highly rated River Plate forward Julian Alvarez, according to media reports in Argentina.。

The Catalan giants have sent scouts to observe Alvarez in Argentina's Primera Division and could make a move for the 21-year-old in the January transfer window, the Ole news outlet said on Friday.。

It added that the Blaugrana's interest has been heightened by a hamstring injury to Memphis Depay and uncertainty surrounding the future of Sergio Aguero due to heart problems.。

Capped five times for Argentina's national team, Alvarez is the Primera Division's top scorer this season with 17 goals in 20 matches.。

His performances have reportedly also caught the attention of Juventus, Sevilla, Inter Milan, Bayer Leverkusen, Milan and Fiorentina.。

Alvarez has a 20 million-euro buyout clause in his River Plate contract, which expires next December. However, it is believed the Buenos Aires club could demand twice that figure given the attacker's recent form and growing interest from European suitors. Enditem。

US airport chaos as more than 2,700 flights cancelled******

Air travel continued to be severely disrupted in the United States on Saturday, with bad weather in parts of the country adding to the impact of a massive spike in COVID-19 infections fuelled by the Omicron variant.。

The United States had 2,723 canceled flights, more than half of the 4,698 canceled worldwide, around 11:00 pm (0400 GMT Sunday), according to tracking website FlightAware.。

In addition, 5,993 domestic flights were delayed on Saturday, out of a total of 11.043 worldwide for the day.。

The worst affected US airline was SkyWest, which had to cancel 23 percent of its flight schedule, according to the site.。

In the United States, airports in Chicago were particularly hard-hit because of bad weather, with a snowstorm expected in the area on Saturday afternoon and into the night.。

The global air travel industry is still reeling from the highly contagious Omicron variant.。

Many pilots, flight attendants and other staff are absent from work after contracting COVID-19, or because they are quarantining after coming in contact with someone who has the infection.。

Some 7,500 flights were canceled by airlines worldwide over the Christmas weekend.。

双语热点:韦伯太空望远镜:怎么让大家见到大量未知的宇宙?******

大家希望的詹姆斯·韦伯太空望远镜(The James Webb Space Telescope ,JWST)将在12月22日发射火箭升空,科技界对它很有可能发觉的宇宙的奥秘激动不已。这台望眼镜的发射,早已延迟了十年之久,成本也大幅度超过预算约90亿美金。好多个小问题来简易了解一下这台深受希望的望远镜吧。

What is the James Webb Space Telescope and when will it launch?

Nasa is preparing to launch a space telescope that will see further into the Universe than anything else ever built.。

美国国家航空航天局(NASA)正提前准备发射一个太空望远镜,它将比过去修建的一切望眼镜要看得很远。

The James Webb Space Telescope (JWST) has taken 30 years and $10bn (£7.5bn) to develop, and is being described as one of the grand scientific endeavours of the 21st Century.。

詹姆斯·韦伯太空望远镜(JWST) 的开发设计用时 30 年,斥资 100 亿美金(75 亿英镑),被觉得是 21新世纪最宏伟的科学探索之一。

What is the goal of this telescope?

詹姆斯·韦伯太空望远镜的每日任务有什么?

The telescope will be able to see just about anything in the sky. However, it has one overriding objective - to see the light coming from the very first stars to shine in the Universe.。

詹姆斯·韦伯太空望远镜将可以见到天空中的任何东西。殊不知,它有一个重中之重——探索世界最开始产生时第一批星系传出的光。

These pioneer stars are thought to have switched on about 100-200 million years after the Big Bang, or a little over 13.5 billion years ago.。

这种最开始星系被觉得是在爆发后差不多1亿到2亿光年,也就是大概 135 亿光年前打开的。

Why would we want to see the first stars?

为何我们要见到第一批星系?

这个由近万个星系构成的图像被称为哈勃超深空(the Hubble Ultra Deep Field),由哈勃太空望远镜在环绕地球400圈后积累影像数据而成。  这一由近万只星系组成的图象被称作哈勃超太空(the Hubble Ultra Deep Field),由哈勃太空望远镜在环绕地球400圈后累积影象数据信息而成。

When the Universe was formed in the Big Bang, it contained only three chemical elements - hydrogen, helium and a smattering of lithium.。

当宇宙空间在爆发中产生时,它只包括三种化学分子——氢、氦和少许的锂。

Every other chemical element - including those vital to life, such as carbon and oxygen - had to be forged, or "manufactured", by nuclear reactions at the centre of stars.。

全部别的化学分子——包含这些对性命尤为重要的原素,如碳和氧——都需要根据行星核心的核反应煅造或“生产制造”。

Webb will help us understand the origins of everything we see around us, and how we came to be.。

韦伯将协助大家知道大家周边所闻的一切事情的发源,及其我们都是怎样产生的。

How does Webb differ from existing space telescopes?

韦伯与目前的太空望远镜有哪些区别?

美国国家航空航天局的哈勃太空望远镜显示出创世之柱在可见光和近红外光中显得多么不同。美国国家航空航天局的哈勃太空望远镜表明出创世之柱在能见光和近红外线中看起来多么的不一样。

It's much bigger than the Hubble telescope, which has been orbiting Earth since 1990.。

它比自 1990 年至今一直紧紧围绕地球上运作的哈勃望眼镜大很多。

Hubble collects light using a main mirror that's 2.4m (7.8ft) across, while Webb has a primary mirror that's 6.5m in diameter.。

哈勃应用直徑为 2.4米(7.8 英寸)的主镜搜集光源,而韦伯则应用直徑为 6.5米的主镜。

With all the other associated equipment, Webb is about the size of a tennis court. It's so big, in fact, it has to be folded to fit inside its launch rocket.。

再加上全部别的有关机器设备,韦伯大概有一个网球场地那么大。实际上,它太大,务必折叠式起來才可以放进发射火箭弹。

But the key aspect of Webb is that it is tuned to detect light that Hubble cannot - in the infrared. This light is invisible to the human eye, but it's the type of light in which the glow from the most distant objects in the Universe will show up.。

但韦伯的主要优点是它通过调节,可以搜集到哈勃没法搜集到的光——红外线。这类仅是人眼见看不到的,但它是宇宙空间中最漫长物件会传出的光的种类。

When will it launch?

什么时候发射火箭升空?

At the moment, Webb - named after James E Webb, the Nasa boss who oversaw the Apollo Moon-landing project - is scheduled to go into orbit on Wednesday 22 December.。

现阶段,这台以承担阿波罗登月新项目的美国nasa厅长詹姆斯·韦伯的名称定名的太空望远镜方案于 12 月 22 日星期三进到路轨。

It will be launched on a European Ariane-5 rocket from French Guiana. The European Space Agency is a partner on the project, and has agreed to take on the responsibility of getting Webb into space.。

它将由欧洲地区亚利安5号火箭弹从法属圭亚那发射进到外太空。欧洲航天局是此项目地合作方,并允许担负将韦伯送进外太空的义务。

How much has Webb cost and why?

韦伯的斥资是多少,为什么消耗这般极大?

Nasa spent $8.8bn on Webb's design and build, and it will put in a further $860m to support five years of mission operations.。

美国nasa在韦伯的制定和修建上耗费了 88 亿美金,并将再资金投入 8.6 亿美金来适用五年的每日任务运作。

The European Space Agency has invested about €700m (£590m) in the project, contributing to two of Webb's four instruments and providing the Ariane launch rocket. The Canadian Space Agency (CSA) also put in about CA$200m (£120m).。

欧洲航天局已在该新项目中项目投资了约 7 亿欧(5.9 亿英镑),为韦伯的四台仪器设备中的两部作出了适用,并出示了阿丽亚娜火箭发动机。澳大利亚航天部门 (CSA) 也资金投入了约 2 亿加元(1.2 亿英镑)。

It all adds up to a figure in excess of $10bn (£7.5bn; €9bn; CA$12.7bn).。

这一切斥资加起來超出 100 亿美金(75 亿英镑;90 亿欧;127 亿加元)。

It's true Webb is years behind schedule, and it's suffered on occasions from poor project management. But some of the money has been spent on technology developments that have had wider application elsewhere - for instance, a measurement tool created for Webb is now used in precision eye surgery.。

的确,韦伯比方案晚了很多年,并且它有时候会遭受项目风险管理不当的危害。但一部分钱已用以在其它层面更普遍的运用——比如,为韦伯建立的测量仪器如今用以高精密眼科手术。

For context, Hubble has so far cost close to $15bn in today's prices. Few would doubt its worth after all its discoveries over the past 30 years, and the James Webb Space Telescope is expected to be no less revolutionary.。

目前为止,哈勃以今日的价钱测算的成本费已贴近 150 亿美金。非常少有的人会猜疑它过去 30 年来的使用价值,并且詹姆斯·韦伯太空望远镜预估也一样具备颠覆性。
