🔥🔥🔥🔥 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.

Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site. Founder Pavel Durov says tech is meant to set you free And while money initially moved into stocks in the morning, capital moved out of safe-haven assets. The price of the 10-year Treasury note fell Friday, sending its yield up to 2% from a March closing low of 1.73%.
