🔥🔥🔥🔥 Olimlar Yer yuzida eng qadimgi meteorit kraterining izlarini aniqladilar
Uning yoshi 3,47 milliard yil bo‘lib, avvalgi eng qadimgi deb hisoblangan Yarrabubba krateridan (2,23 milliard yil) 1,2 milliard yilga qadimgi ekanligi ma’lum bo‘ldi.
U G‘arbiy Avstraliyaning Sharqiy Pilbara hududida, Antarctic Creek Member jins qatlamida topildi. Asosiy dalillardan biri “singan konuslar” bo‘lib, ular jinslarda hosil bo‘lgan konussimon yoriqlar bo‘lib, kuchli bosim ta’sirida paydo bo‘lgan. Tadqiqotchilarning baholariga ko‘ra, bu kraterning diametri kamida 100 km bo‘lgan.
Olimlarning fikricha, bunday ulkan ta’sirlar qit’alarning shakllanishiga, vulqonlarning faollashishiga va hayotning paydo bo‘lishiga yordam bergan bo‘lishi mumkin. Krater qatlamlarida qadimgi qazilma qoldiqlari ham topilgan bo‘lib, ular dastlabki fotosintez qiluvchi mikroorganizmlarga bog‘liq bo‘lishi ehtimoli bor.

The original Telegram channel has expanded into a web of accounts for different locations, including specific pages made for individual Russian cities. There's also an English-language website, which states it is owned by the people who run the Telegram channels. "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. Soloviev also promoted the channel in a post he shared on his own Telegram, which has 580,000 followers. The post recommended his viewers subscribe to "War on Fakes" in a time of fake news. Telegram, which does little policing of its content, has also became a hub for Russian propaganda and misinformation. Many pro-Kremlin channels have become popular, alongside accounts of journalists and other independent observers. A Russian Telegram channel with over 700,000 followers is spreading disinformation about Russia's invasion of Ukraine under the guise of providing "objective information" and fact-checking fake news. Its influence extends beyond the platform, with major Russian publications, government officials, and journalists citing the page's posts.
