На заседании Ученого совета ИТФ в пятницу 24.04 будет заслушан 1 доклад: 11:30 М.А. Шишкин, Е.С. Пикина, В.В. Лебедев Режимы жемчужной динамики везикул Мы изучаем &quot;pearling instability&quot; вытянутых везикул под натяжением [Bar-Ziv and Moses, PRL, 1994], сходную классической неустойчивости Рэлея-Плато. В первую очередь мы строим аналитическую теорию маргинальных мод при плавно изменяющемся вдоль везикулы поверхностном натяжении. Это позволяет объясняснить расхождение между численным моделированием динамики в растягивающем потоке [Narsimhan et al., JFM, 2015], где неустойчивость распространяется от краев, и экспериментами [Kantsler et al., PRL, 2008]: учёт небольшого маргинального возмущения в нашем моделировании приводит к образованию первых жемчужин именно в центре. После формирования жемчужин динамика определятся зависимостью растягивающей силы от длины везикулы: возможен каскад неустойчивостей или квазистационарный режим. В последнем случае медленная динамика связана с перекачкой жидкости между жемчужинами; при локализованном воздействии на краях, крупные жемчужины поглощают мелкие. Рассматривая &quot;свободные жемчужины&quot; как солитонные стационарные решения на цилиндрическом фоне, мы устанавливаем убывающий характер зависимости поверхностного натяжения от размера жемчужины, что и объясняет неустойчивость состояния с несколькими жемчужинами.

The Nancy Grace Roman Space Telescope, NASA's next great observatory, is finally complete! When will it fly?

The Nancy Grace Roman Space Telescope is finally complete! | Space Quiz! What year did NASA's Curiosity rover land on Mars? | Spectacular photos of the 2026 Lyrid meteor shower Created for znamenski.spacecom@blogger.com | Web Version   April 22, 2026 FOLLOW US FOLLOW US   Taking you out of this world, every day SIGN UP ⋅   WEBSITE   The Launchpad The Nancy Grace Roman Space Telescope is finally complete! Happy Wednesday, Space Fans, and welcome to your midweek briefing from space. Our top story today is pretty exciting. After all, how often do we get a brand-new space telescope off the assembly line? NASA's next great observatory, the Nancy Grace Roman Space Telescope, is now fully assembled, and if you thought Webb and Hubble were impressive, wait 'til you see what's coming in the story above. And, of course, that's not all. We have some stunning Lyrid meteor shower photos, meet the divers that welcomed Artemis 2 astronauts and see a tantalizing Mars discovery that may have implications for life in the stories below. Check them out! What will it see? Space Quiz! What year did NASA's Curiosity rover land on Mars? Find the answer HERE! 2012 1997 2021 1969   Trending Spectacular photos of the 2026 Lyrid meteor shower Today may be Earth day, but we can't help but keep looking up to see pieces of asteroid Phaethon spark brilliant meteors for the Lyrid meteor shower. Here's our favorite photos so far. Shooting stars! Spaceflight Meet the Navy divers who welcomed Artemis 2 home When NASA's Artemis 2 astronauts returned to Earth after their mission, it wasn't NASA that welcomed them home. It was the U.S. Navy and a crack team of divers that opened their Orion hatch first. Here's who they were and how they did it. In the Navy! Blue Origin New Glenn rocket grounded after launch failure Blue Origin successfully reused and landed a New Glenn Rocket stage. But its goal of delivering a huge mobile phone satellite into orbit, well that went less well. So what comes next? Will it fly again? Skywatching See the moon and Jupiter after sunset tonight The Lyrids are the only night sky sight to see this Earth Day. The moon and Jupiter will shine close together just after sunset. But where should you look? We're glad you asked... Where should I look? Search for Life Curiosity rover finds building blocks of life on Mars NASA's Curiosity rover has found a diverse mix of organic molecules on Mars, including chemicals considered building blocks for the origin of life on Earth. But the big question? Scientists aren't sure how they got there. Are we close to life? Science & Astronomy Mysterious rings around Uranus point to hidden moons From Mars to Uranus - (no jokes, please) - where the strange tilted rings of the ice giant are revealing new clues, including potential hidden moons. Here's what we know. Where are the moons? Today in Space Photo of the day: Celebrate Earth Day with Artemis 2 (NASA) Today is Earth Day and how better to celebrate than with this stunning view of the entire Earth from space. Called "Hello, World!" this view was taking by NASA's Artemis 2 astronauts from deep space while headed to the moon. See how it was made here. Learn about the photo On this day in 2010: X-37B space plane on 1st secret mission For our space history flashback today, we're going back to 2010, when a miniature space shuttle - originally developed for NASA - launched into orbit for the 1st time on a secret mission for what was then the U.S. Air Force. Here's how it happened here. Watch the video Space deal of the day What are the best value streaming services for sci-fi fans? With so many streaming services out there, sci-fi fans are spoiled for choice. From Amazon Prime to Netflix and beyond, we've rounded up the best value streaming services for science fiction.  See the deals Editor's Note Have a great Wednesday! And that's a wrap for our daily space update. Thanks for reading to the end and we'll give you a sneak peek at tomorrow's newsletter. Have you ever wondered what the Artemis astronauts will WEAR on the moon? Well, so have we, and we'll have an Artemis spacesuit update tomorrow! Don't miss it! Keep looking up!
