❗️Астрономы зафиксировали одну из мощнейших в истории наблюдений ударных звуковых волн, которая когда-либо достигала Земли из космоса, об этом говорится в исследовании, опубликованном в журнале Monthly Notices of the Royal Astronomical Society (MNRAS).
По данным ученых, столкновение произошло в группе галактик Квинтет Стефана, которая расположена в 290 млн световых лет от Земли. Удалось установить, что галактика под названием NGC 7318b на скорости в 3,2 млн км/ч врезалась в четыре других. Это привело к появлению гиперзвуковой ударной волны.

But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future. "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. There was another possible development: Reuters also reported that Ukraine said that Belarus could soon join the invasion of Ukraine. However, the AFP, citing a Pentagon official, said the U.S. hasn’t yet seen evidence that Belarusian troops are in Ukraine. Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications.
