星系、喷流与著名的黑洞
影像提供:NASA,JPL-Caltech,Event Horizon Telescope Collaboration

说明:明亮椭圆星系梅西叶87(M87)核心的超大质量黑洞,是地球上的事件视界望远镜,在2017年拍摄的史上首张黑洞影像的主角。约5500万光年远的M87,是室女星系团的庞大成员星系,而在来自史匹哲太空望远镜的红外光底图里,M87是其中以泛蓝色阶呈现的大星系。虽然M87看起来像一团平淡无奇的云状天体,但史匹哲的影像,却能清楚的记录下从此星系核心射出的相对论性喷流之细微结构。右上角的嵌图中显示,这些喷流本身长达数千光年。嵌图右方较明亮的喷流往我们靠,而且其指向离我们的视线不远。与其反向的不可见远离喷流,冲撞并激发辐射出暗淡辉光的物质弧。右下角的嵌图,则是上文所提到的、位于庞大星系及相对性喷流中心的黑洞之历史性影像。史匹哲的影像里完全未能解析的,是被超大质量黑洞吸积在周围的内坠物质环,而它们更是驱动源自活跃星系M87核心的相对论喷流之庞大能量源。事件视界望远镜的M87影像经过强化,以更清晰的呈现这个著名的超大质量黑洞。

Newly uncovered hack campaign in Telegram

The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
