🔥🔥🔥🔥 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.

Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. 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.

And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. On Feb. 27, however, he admitted from his Russian-language account that "Telegram channels are increasingly becoming a source of unverified information related to Ukrainian events."
