📸تصویر روز ناسا: مجموعه ستاره‌ای NGC 206 با ستارگانی جوان
🔸ستاره NGC 206، یکی از بزرگ‌ترین و درخشان‌ترین مجموعه‌های ستاره‌ای شناخته‌شده، همراه با مناطق ستاره‌زایی صورتی‌رنگ در بازوهای غبارآلود کهکشان آندرومدا قرار گرفته است. این کهکشان مارپیچی که با نام M31 نیز شناخته می‌شود، نزدیک‌ترین کهکشان بزرگ به کهکشان راه شیری است و تنها ۲.۵ میلیون سال نوری با ما فاصله دارد.

"Someone posing as a Ukrainian citizen just joins the chat and starts spreading misinformation, or gathers data, like the location of shelters," Tsekhanovska said, noting how false messages have urged Ukrainians to turn off their phones at a specific time of night, citing cybersafety. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. In this regard, Sebi collaborated with the Telecom Regulatory Authority of India (TRAI) to reduce the vulnerability of the securities market to manipulation through misuse of mass communication medium like bulk SMS. Ukrainian forces successfully attacked Russian vehicles in the capital city of Kyiv thanks to a public tip made through the encrypted messaging app Telegram, Ukraine's top law-enforcement agency said on Tuesday. "The inflation fire was already hot and now with war-driven inflation added to the mix, it will grow even hotter, setting off a scramble by the world’s central banks to pull back their stimulus earlier than expected," Chris Rupkey, chief economist at FWDBONDS, wrote in an email. "A spike in inflation rates has preceded economic recessions historically and this time prices have soared to levels that once again pose a threat to growth."
