На заседании Ученого совета ИТФ в пятницу 15.05 в рамках коллоквиума будет заслушан доклад: 11:30 А.Г. Погосов (ИФП СО РАН) Электронная гидродинамика в GaAs: от вязкости к вихрям и турбулентности В достаточно чистых двумерных электронных системах межэлектронные столкновения могут доминировать над рассеянием на примесях и фононах, вследствие чего электронный транспорт приобретает коллективный гидродинамический характер. В этом режиме электронный газ в GaAs микроструктурах может рассматриваться как вязкая жидкость, для описания которой оказываются применимы понятия классической гидродинамики — вязкость, граничные условия, вихревое течение и турбулентность. В докладе будет представлен обзор наших недавних экспериментальных исследований электронной гидродинамики в высокоподвижных GaAs гетероструктурах. Будет показано, как эффект сверхбаллистики позволяет проводить измерения электронной вязкости и её температурной зависимости, а также анализировать проскальзывание электронной жидкости, задающее граничные условия на краях образца. Далее будут обсуждаться эксперименты по наблюдению стационарных электронных вихрей с помощью транспортных измерений. Особое внимание будет уделено эксперим ентальному подтверждению наличия вихрей и обоснованию их гидродинамической природы. Будет продемонстрирована твердотельная реализация электронного клапана Теслы, что является первым экспериментальным признаком электронной турбулентности. Наконец, будут рассмотрены необычные механические методы регистрации электронных вихрей, основанные на взаимодействии магнитного момента вихря, локализованного на наномеханическом резонаторе, с магнитным полем.

How SpaceX's new Starship 'V3' differs from its predecessors

The world's biggest rocket | Blue Origin lunar lander mockup is ready for astronauts | Artemis 3 will be 'one of the most highly complex missions' Created for znamenski.spacecom@blogger.com | Web Version   May 14, 2026 FOLLOW US FOLLOW US   Taking you out of this world, every day SIGN UP ⋅   WEBSITE   The Launchpad The world's biggest rocket As the weekend approaches, we're still watching for the latest updates about SpaceX's upcoming test flight of its massive Starship V3. Our own Josh Dinner has a rundown of how this new version of Starship differs from its predecessors in not only height, but in the number of grid fins it sports, how it feeds fuel to its Raptor engines, and more.  Aside from tracking Starship test flight updates, we've been exploring new ways that astronomers might detect alien life using existing spacecraft and even interviewed Neil deGrasse Tyson about his new book exploring what possible alien encounters might be like from a scientific perspective. Today we've also got a look at why Venus is currently stealing the show in the night sky, some gorgeous backyard astrophotography, and a dive into a new study that proposes the ice giants Uranus and Neptune might actually be full of rocks. There's always something amazing to learn in space! A whole new Starship   Spaceflight Blue Origin lunar lander mockup is ready for astronauts A mockup of Blue Origin's Blue Moon Mark 2 lunar lander has been assembled at the Johnson Space Center, and is ready for Artemis astronauts to come aboard to begin training. Blue Moon moves forward Artemis 3 will be 'one of the most highly complex missions' NASA just revealed some new details about its upcoming Artemis 3 astronaut mission to Earth orbit, which is targeted to launch in late 2027, calling it "one of the most highly complex missions NASA has undertaken." Artemis 3 details Skywatching What's that bright light after sunset? As dazzling Venus dominates the evening sky, May is the perfect moment to start a months-long love affair with the brightest planet. Month of Venus Astrophotographer captures galactic 'Eyes' Astrophotographer Ronald Brecher has captured a breathtaking view of Markarian's Chain — a string of majestic galaxies glowing in the patch of sky between the constellations Leo and Virgo. Cosmic eyes Search for Life Scientists say we can find aliens with existing spacecraft Scientists say amino acids produced by life are distributed differently and more diversely than amino acids produced by non-living chemical reactions, thereby providing a truer signature of life. The trick isn't to just search for biosignatures, but rather to look at how they are organized — and the Europa Clipper has an instrument for this.   Alien biosignatures What happens if you meet aliens? Ask Neil deGrasse Tyson Delivering a refreshing fusion of science, pop culture, history, and esoteric humor, renowned astrophysicist, lecturer, and best selling author Neil deGrasse Tyson takes us on a whirlwind tour of UFO culture and speculations on how first contact might actually happen in his latest book, "Take Me To Your Leader: Perspectives on Your First Alien Encounter." Step 1: Get better data Science & Astronomy Uranus and Neptune could be full of rocks Uranus and Neptune are two planets that have historically been classified and thought of as "ice giants," orbiting far out in the freezing edges of our solar system. But it's possible that our understanding of these planets' makeup could be totally off, and their atmospheres could be full of rocks, researchers suggest in a new study. Rock giants?

Photo of the Day Entertainment 'Smallville' at 15: The best Clark Kent story ever told Look! Up in the sky! It's a bird! It's a plane! No, it's non-canonical Superman! But at its core, it's still the most human story about the man beneath the Man of Steel. A more human Superman Editor's Note There's never a dull moment in the space world. Tomorrow, NASA's Psyche probe will make a close approach to Mars on its way to visit a metal asteroid. Keep an eye out on Space.com for some fascinating imagery from the fly-by.   We'll also have a look at how satellite megaconstellations might be altering Earth's atmosphere in what some scientists call an 'unregulated geoengineering experiment'. And just what exactly does the new film 'Devil Wears Prada 2' have to do with NASA?   Follow us here at Space.com as we find out! And as always, from our team, thanks for reading.
