银河系中心的人马座C（Sagittarius C）是一处物质丰富的恒星育婴室，却长期以来呈现异常低的恒星形成率。天文学家利用韦伯太空望远镜的观测资料推测，该区域中的强磁场可能是抑制恒星形成的主因。人马座C距离银河系中心的超大质量黑洞约 200 光年，是银河中心附近一个重要的恒星形成区域。这里拥有大量高密度的气体与尘埃，理论上应能有效孕育众多恒星，然而实际观测却显示，当地的恒星形成率远低于预期。透过韦伯太空望远镜的红外线观测，天文学家得以穿透稠密的尘埃，窥见银河中心附近的恒星诞生现场。韦伯的影像中，人马座C周围可见大量细长的丝状结构。这类结构过去曾由地面望远镜观测到，韦伯望远镜的资料则提供了更清晰的画面与有力的佐证。研究团队推测，这些丝状结构的形成与当地强磁场密切相关。银河系中央黑洞所产生的强大潮汐力使气体剧烈流动，进而拉伸并增强周围的磁场，而磁场则进一步形塑出这些丝状结构。 NASA Webb Explores Effect of Strong Magnetic Fields on Star Formation 天文館:銀河中心強磁場可能抑制恆星誕生

The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
How Does Bitcoin Mining Work?
Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
