🌌 سرنخی از ماده تاریک 🌌

تصویر پرتو ایکس تلسکوپ ROSAT از یک خوشه کوچک کهکشانی به نام گروه NGC 2300.
این تصویر نشان می‌دهد که گروه کهکشانی NGC 2300 در یک ابر عظیم از گاز داغ (به رنگ بنفش) با قطر ۱.۳ میلیون سال نوری غوطه ور است.

سرنخ موجود برای حضور ماده تاریک این است که ابر داغ باید مدت‌ها پیش در فضا پراکنده می‌شد مگر اینکه توسط گرانش یک جرم عظیم در کنار هم نگه داشته شده باشد.

-فاصله: ۱۵۰ میلیون سال نوری
-واقع در صورت فلکی قیفاووس

Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis." "The argument from Telegram is, 'You should trust us because we tell you that we're trustworthy,'" Maréchal said. "It's really in the eye of the beholder whether that's something you want to buy into." Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. "There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations.
