天文学家揭示了银河系中心黑洞的第一张照片
5月12日，在世界各地同时举行的新闻发布会上，天文学家向人们展示了位于银河系中心的超大质量黑洞的首张照片。 这一结果提供了压倒性的证据，证明该物体确实是一个黑洞，并为理解星系中心的这些“巨兽”如何运作 提供了有价值的线索。 该图像由一个名为「事件视界望远镜 (EHT) 合作组织」的全球研究团队，通过分布在全球的射电望远镜组网“拍摄”而成。

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
