Скопление Снежинкки (NGC 2264) — это скопление молодых звёзд возрастом от одного до пяти миллионов лет. Для сравнения, Солнце — звезда среднего возраста, которой около 5 миллиардов лет, то есть оно примерно в 1 000 раз старше, отмечают в NASA.

At its heart, Telegram is little more than a messaging app like WhatsApp or Signal. But it also offers open channels that enable a single user, or a group of users, to communicate with large numbers in a method similar to a Twitter account. This has proven to be both a blessing and a curse for Telegram and its users, since these channels can be used for both good and ill. Right now, as Wired reports, the app is a key way for Ukrainians to receive updates from the government during the invasion. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. WhatsApp, a rival messaging platform, introduced some measures to counter disinformation when Covid-19 was first sweeping the world. Messages are not fully encrypted by default. That means the company could, in theory, access the content of the messages, or be forced to hand over the data at the request of a government. Stocks dropped on Friday afternoon, as gains made earlier in the day on hopes for diplomatic progress between Russia and Ukraine turned to losses. Technology stocks were hit particularly hard by higher bond yields.
