Meteorite diamond8/1/2023 ![]() ![]() ![]() The images revealed inclusions (impurities) of sulfur, iron, and a mineral called chromite, as well as warping of the diamond crystal and nearby graphite.Īccording to the researchers, this means the diamonds formed at the extreme pressure of 20 gigapscals - about 180 times as crushing as the pressure found at the bottom of the Marianas Trench, the deepest point in Earth's oceans. ![]() This means the rock that fell to Earth nearly a decade ago was part of a "lost" planet formed - and completely destroyed - at the dawn of the solar system. Scientists now think those gems and the impurities found inside them could only come from the heart of a Mercury-to-Mars-size planet. Meteorite hunters recovered about 50 fragments, which researchers later named the "Almahata Sitta" collection after a nearby train station in Sudan.īut while many stony meteorites hail from Mars, these were peculiar: They contained a bunch of tiny diamonds. The stony meteorite, called asteroid 2008 TC 3, plunged through the atmosphere, exploded, and rained its pieces over the Nubian Desert in Africa. Asteroid TC 3, as it's called, may be the first pristine chunk of a "lost" planet ever recovered on Earth.Īfter a 4.5-billion-year journey through space, a car-size rock fell to Earth on October 7, 2008.Scientists think the planet was destroyed 4.5 billion years ago and was the size of Mercury or even Mars.The diamonds and impurities found inside them suggest the rock came from inside a planet.A meteorite that fell to Earth in October 2008 contained scores of small diamonds.According to Christoph Salzmann, a chemist at University College London and co-author of a paper describing the research, “through the controlled layer growth of structures, it should be possible to design materials that are both ultra-hard and also ductile, as well as have adjustable electronic properties from a conductor to an insulator. Now, these graphene growths can be studied and possibly be made in a lab. Lonsdaleites are named after Dame Kathleen Lonsdale, a British crystallographer and University College London’s first female professor.īut, while they were studying the lonsdaleite in the meteorite, the team found that instead of the pure hexagonal structures they were expecting, the structures had “growths of another carbon-based material called graphene interlocking with the diamond.” Known as diaphites, these growths have a layered pattern inside the meteorite that “don’t line up perfectly,” according to a statement by the researchers. Rather, lonsdaleite diamonds – naturally formed only when asteroids strike Earth at enormously high speeds – have a hexagonal crystal structure and form only under extremely high pressures and temperatures. These unique diamond structures inside the Canyon Diablo meteorite, which hit Earth 50,000 years ago and was discovered in Arizona in 1891, are nothing like the diamonds we all know and picture. An international study led by UCL (University College London) and Hungarian scientists found a never-seen-before structure – an interlocking form of graphite and diamond – inside a meteorite that hit Earth 50,000 years ago.Īccording to an article on Live Science, the structure has unique properties “that could one day be used to develop superfast charging or new types of electronics”. ![]()

Alaunch cfm8/1/2023 ![]() It’s unclear whether the Ti models will have GDDR6 or GDDR6X memory, but the latter seems likely.Īpart from the size of the memory, the trio of GPUs remain a bit of an enigma. The GPUs on Nvidia’s radar are the RTX 4060 Ti with 16GB of VRAM, followed by the RTX 4060 Ti 8GB and the RTX 4060 8GB with GDDR6 memory. The Better Bus Network Redesign builds on the previously completed Bus Transformation Project (BTP), a comprehensive study conducted in partnership with local agencies, to create a plan to transform bus service.įor more information and to participate in the Better Bus Experience LAB or Experience LIVE!, please visit /betterbus.Ĭustomers are also encouraged to sign up for MetroAlerts text and email messages, follow us on Twitter or go to /alerts to get the latest service updates.MegaSizeGPU claims that Nvidia has three GPUs planned in the coming months, but only one of them is slated for a May release. The proposal will allow Metro to better connect people to where they want to go through an easy-to-use bus network, no matter where customers are. The network redesign incorporates feedback gathered in the first phase last fall, including more than 11,000 people, as well as bus operators and our regional transit partners. 1.1 million residents across the region will have 24-hour bus service 307,000 more will have late-night bus service (10 p.m.123,000 and 208,000 more residents on Saturdays and Sundays will have bus service.64% more people with access to high-frequency bus service on Sundays.73% more people with access to high-frequency bus service on Saturdays.Under the draft Visionary Network, more people would have access to more bus service, seven days a week, 24-hours a day including: "Our region needs a network that matches when and where people want to travel, addresses inequities, and gets more people on buses and out of cars providing environmental benefits to the region." "We are committed to providing fast, frequent, and reliable service that is a quality experience for our customers and operators," said General Manager and Chief Executive Officer Randy Clarke. The draft Visionary Network provides a long-term roadmap to create the bus network the region needs. ![]() The bus network envisioned under the draft proposal includes expanding the high frequency service network from 36 routes to approximately 100 routes that would operate every 20 minutes or less, regional 24-hour bus service, more routes operating seven days a week, and more direct connections to where customers want to go. The draft Visionary Network is the first step to getting there and creating a more equitable transit network." ![]() "We want people to take the bus because it's the best, most reliable and sustainable option. "We want to create a bus network that is easier for customers to use, more efficient, and aligned with where and when people want to travel," said Metro Board Chair Paul C. The Better Bus "Experience LIVE!" will include in-person workshops, community pop-up events, and virtual "lunch and learns." The virtual "Experience LAB" will also offer people an interactive tool that enables customers to compare their trip today to their routes in the draft Visionary Network, as well as a map library to explore route profiles and the network as a whole. Starting Monday, April 17 through Monday, June 5, Metro will host community-focused events across the region and launch an interactive website where customers can explore the reimagined bus network and provide input. During this phase, Metro will also provide a first look at the draft Visionary Network of the future that provides frequent, fast, and reliable service, matches the region's changing travel needs, advances equity and sustainability, and increases access to opportunities. Metro today announced 50 events in 50 days kicking off the next phase of its Better Bus Network Redesign.
