研究表明靠近地球的超新星爆发可能导致了至少两次大规模灭绝事件。研究人员认为，分别发生在 3.72 亿年前和 4.45 亿年前的晚泥盆纪和奥陶纪灭绝事件是地球附近的超新星爆发导致的。奥陶纪灭绝事件杀死了 60% 的海洋无脊椎动物，当时的生命大部分生活在海洋里。晚泥盆纪灭绝事件杀死了 70% 的物种。科学家认为这两起灭绝事件与臭氧层损耗相关，而这可能是超新星引发的。研究人员称，这两次灭绝事件的时间与地球附近超新星爆发的频率一致。 DOI 10.1093/mnras/staf083 Eurekalert: Violent supernovae 'triggered at least two Earth extinctions'

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
