(Xinhua/Emmanuel Herman)     Tanzanian President Samia Suluhu Hassan on Saturday inaugurated the 2,115-megawatt Julius Nyerere Hydropower Plant, a landmark project expected to strengthen electricity supply and accelerate industrial and economic development.
Hassan inaugurated the plant in Rufiji District in Coast Region, saying the new generation capacity should produce measurable gains in manufacturing, trade, mining, modern agriculture, public services, investment and employment.
The nine-unit facility now accounts for nearly half of electricity dispatched to Tanzania's national grid, significantly improving reliability and security of supply, she said.
"This project has demonstrated Tanzania's capabilities. We must now harness that capacity to advance other strategic projects and build a strong, self-reliant nation," Hassan said.
Built with the participation of China's Power Construction Corporation of China (PowerChina) and Dongfang Electric Corporation, the plant has a total installed capacity of 2,115 megawatts, Zhang Rui, the project manager with PowerChina, said.
PowerChina undertook the construction of the main works, including the main dam, the stilling basin, the water conveyance system, the diversion tunnels and the metal structures, as well as the overall engineering design and the supporting facilities, Zhang said.
Tan Jin, the project manager with Dongfang Electric, noted that they supplied all nine hydro-turbine generator units, main inlet valves and other complete sets of electromechanical equipment, and carried out their installation, commissioning and trial operation.
During construction, the China-involved construction work created about 14,000 jobs for local residents. Thousands of Tanzanians received professional skills training from Chinese engineers in areas such as welding, steel fixing, carpentry, heavy machinery operation and surveying, helping build a stronger local workforce, according to the two managers.
The project is also expected to improve electricity supply for households and public services, strengthen Tanzania's role in the regional energy market in East Africa, and provide reliable energy support for regional connectivity and socioeconomic development, said Humphrey Moshi, an economics professor at the University of Dar es Salaam in Tanzania.

。      据最新一期《自然》杂志报道，美国麻省理工学院、奥地利科学技术研究院等机构研究人员利用詹姆斯·韦布空间望远镜（JWST），在宇宙诞生后约6.6亿年的宇宙黎明时期发现了迄今已知最早的“黑洞星”。

二 | 这一由快速成长黑洞及致密气体构成的奇特天体，或有助于揭开神秘“小红点”的真实身份，并为解释早期宇宙超大质量黑洞的快速形成提供线索。  超大质量黑洞通常潜伏在大质量星系中心，质量可达太阳的数百万至数十亿倍。然而，科学家一直难以解释，为何在宇宙诞生后仅数亿年，就已经出现了一些质量巨大的黑洞。

三 |   此次发现的天体被命名为“MoM-BH*-1”。研究人员原本利用JWST寻找宇宙早期星系，却在观测数据中发现一个异常明亮、颜色偏红的光点。它的尺度只有太阳系大小，但能量输出却约为普通恒星产生的能量上限的1000亿倍，远超普通恒星核聚变所能达到的水平。  与此同时，MoM-BH*-1的光谱还呈现出一种异常强烈的“巴耳末跳跃”，这种光谱特征通常与恒星大气中的致密气体有关。同时，其光谱中几乎没有金属元素的明显痕迹，主要表现为氢和氦的特征。

四 |   研究人员模拟发现，极其致密的氢气可形成类似“巨大恒星表面”的气体包层，吸收特定波长的光，从而解释其特殊光谱。  但这仍无法解释它惊人的亮度。进一步分析显示，最符合观测结果的情景是：MoM-BH*-1中心有一个约为太阳质量10万倍的黑洞，周围包裹着近似太阳系大小的致密氢气。

五 | 黑洞吸积物质释放的能量为整个系统提供动力，外围气体则让它看起来像一颗巨大的恒星——研究人员因此将其称为“黑洞星”。  “黑洞星”的发现还有助于解释JWST近年来频繁发现的神秘“小红点”。这些紧凑、明亮且偏红的天体在早期宇宙中似乎随处可见，却在今天的宇宙中消失殆尽。研究人员发现，如果将类似MoM-BH*-1的天体置于早期星系中，其整体光谱可能与“小红点”高度相似。（记者张佳欣）。
