A |     CARACAS, Venezuela -- Early returns in the Venezuelan opposition's presidential primary gave a big lead to former legislator Maria Corina Machado early Monday, and she quickly claimed victory as the voters' choice to lead the campaign to end the decade-long, crisis-ridden presidency of Nicolás Maduro. The independent National Primary Commission, which organized the primary, did not release any results until long after polling stations closed Sunday, blaming internet censorship. The organizers said that in the first 601,110 ballots counted, about 93% picked Machado, who had entered the vote as a strong front-runner. The rest of the votes were scattered among the other nine candidates. There was no indication of how many people cast ballots in all, and organizers were expected to release additional results throughout Monday.“Today, very powerful forces have been unleashed," Machado told supporters gathered outside her campaign headquarters in the capital, Caracas. “Today, we have shown ourselves what we are capable of doing in the face of all the obstacles, in the face of all the abuses.”Holding Venezuela’s first presidential primary since 2012 required the deeply fractured opposition to work together. Venezuelans, in turn, showed up at voting centers in and outside of their homeland to make it count, enthusiastically lining up for hours despite scorching sun and torrential rain.Still, what they saw as a monumental exercise in democracy could still prove futile, if Maduro’s government wishes.While the administration agreed in principle to let the opposition choose its candidate for the 2024 presidential election, it also has already barred Machado from running for office. Maduro’s government has in the past bent the law, retaliated against opponents and breached agreements as it sees fit.Hundreds of people gathered at voting centers in neighborhoods across Caracas even before polls opened. They stayed in line despite a rainstorm that left them soaking wet. They carried umbrellas, folding stools and coffee to ease the expected waits, and leaned against buildings or stood under marquees to try to avoid the rain. Caracas resident Stephanie Aguilar, 34, cried while she waited to vote. She described the primary as the only “salvation” for her country, her daughter and son, and the millions of Venezuelans who decided they had to emigrate due to the nation’s economic and political turmoil. “We want a better country, a free country, for my children ... who have grown up in this government,” Aguilar, a housewife, said as she wiped tears from her face. “They ask, ‘Mom, can we go out to eat?’ No, there is no money. ‘Mom, can we do this thing?’ No, there is no money. It is unfortunate that a society grows up under those conditions.”Venezuelans typically vote at public schools, but the independent commission that oversaw the primary opted to use homes, churches, private schools and other facilities after electoral authorities did not respond to requests for help in a timely manner.Jesús María Casal, head of the National Primary Commission, blamed the hours-long delay in issuing election results on internet restrictions. “Once we began the process of counting the results ... we detected that our server that functioned as a transmission channel was blocked, which prevents us from completing this process as scheduled,” he said.The London-based internet monitoring firm NetBlocks tweeted metrics showing “a disruption to internet connectivity in #Venezuela with high impact to Caracas." It added that a state-owned internet service provider claimed “an issue with its energy backup system.”David Smilde, an expert on Venezuelan politics at Tulane University, said the primary was a “significant achievement” for several reasons, including forcing political leaders and parties within the opposition “to reach out and speak to the people.”“And it has generated considerable enthusiasm and mobilization in a population that has been skeptical of the opposition leadership of late,” he said.Machado, a proponent of free-market economic policies, is a longtime critic of the governing United Socialist Party of Venezuela. She maintained a somewhat low profile for years but dominated the primary campaign by connecting with the same voters she consistently urged to boycott previous elections.The presidential election is expected to be scheduled for the second half of 2024. Maduro is looking to extend his presidency until 2030, which would surpass the time that Hugo Chávez, his mentor, governed and established his self-described socialist policies.Maduro’s allies ridiculed and dismissed the primary all year. Still, both the government and its opponents used the contest as a bargaining chip to extract concessions from each other as part of a negotiation process meant to end the country’s complex social, economic and political crisis. Maduro and an opposition faction backed by the U.S. government last week agreed to work together on basic conditions for the presidential contest. That prompted the government to release six political prisoners and the Biden administration to lift key economic sanctions. As part of the agreement, Maduro’s administration and the opposition are supposed to “recognize and respect the right of each political actor to select” a presidential candidate freely.If organizers declare Machado the primary's winner, the focus will shift to Maduro to see if the government reverses its ban on her seeking public office. In June, the government issued an administrative decision prohibiting Machado from running, alleging fraud and tax violations and accusing her of seeking the economic sanctions the U.S. imposed on Venezuela in the last decade. The U.S., holding up the threat of renewed sanctions, has given Venezuela until the end of November to establish a process for reinstating all candidates expeditiously.A U.N.-backed panel investigating human rights abuses in Venezuela said last month that Maduro’s government has intensified efforts to curtail democratic freedoms ahead of the 2024 election. That includes subjecting some politicians and other opponents to detention, surveillance, threats, defamatory campaigns and arbitrary criminal proceedings.All registered voters in Venezuela were allowed to participate in the primary, as well as tens of thousands living in several other countries.“This is unprecedented,” said a smiling María de los Ángeles León, 31, the coordinator of Mexico City’s voting site. “People know that we have no guarantees that the winner of this election will be able to advance to the presidential election, but we keep trying.”___Associated Press writer María Verza in Mexico City contributed to this report.。研究人员发现,六光年之外的巨型超级地球行星可能有简单的生命。巴纳德B(或GJ699B)是一颗最近发现的绕巴纳德轨道运行的超级地球行星,它是离地球最近的第二颗恒星。巴纳德B被认为是极冷的,其温度与欧洲相似,大约在零摄氏度以下150度。但研究人员说,它的铁/镍“核心”温度相当高,地热活动非常强烈。维拉诺瓦大学的天体物理学家爱德华·桂南在美国天文学会的一次会议上说:“地热能支持地下生命带,就像南极洲的地下湖泊一样。”“我们知道,欧罗巴的表面温度与巴纳德B的相似。

B | 但是由于地热条件,液态水可能会在木卫二冰冷的表面下。如果存在水,地热可能会导致冷地表下存在液态水的“生命带”。这种情况与结冰的欧罗巴非常相似。”我们已经把注意力集中在巴纳德身上一段时间了,”约拿说。发现巴纳德B行星最重要的意义是在离太阳最近的两个恒星系统中都有行星。”这支持了先前基于开普勒望远镜数据的研究,即行星在银河系中普遍存在,甚至有数百亿个行星。恩格尔说:“巴纳德B被认为是一颗质量超过地球三倍的岩石行星。巴纳德的寿命大约是太阳的两倍。它已经存在了大约90亿年前,太阳存在了46亿年前。

C | 宇宙中的一些行星,即地球的大小,在地球上,甚至在太阳上存在了很长一段时间。巴纳德B的质量是地球的三倍多,其轨道半径与水星的大致相同,在巴纳德(红矮星)周围有233天的轨道周期。朱纳说,虽然亮度很低,但将来可能用一个很大的望远镜“拍摄”巴纳德B,“这样的观测将揭示大气、表面和宜居性的特性。

D | ”虽然表面温度在零下150度左右,但科学家相信冰下有液态水可以维持生命。巴纳德B被认为是一颗岩石行星,比地球大至少3.2倍。

E | 巴纳德B号的主恒星巴纳德距离地球6光年,在天文尺度上距离很短,亮度只有太阳的0.0035倍。离地球最近的唯一恒星系是半人马座阿尔法星,距离地球约4光年。
