Always worth celebrating. And, as always, we've got a lot to share from outer space. Starting with some strange science, astronomers have discovered the first "microquasar" in the Milky Way. This black hole-powered particle accelerator is blasting near-light-speed plasma jets at our home planet -- wild! On the spaceflight front, we are just days away from SpaceX's next Starship launch. And we can now report that launch rehearsal for Flight 14 went swimmingly, so our fingers are crossed for this next test flight. And taking things back down to planet Earth, NOAA's GOES-18 satellite has spotted a terrifying, swirling, lightning-filled view of Hurricane Polo as it approaches the coast of Mexico.  Check out what's big in space below: What's a microquasar?   Trending Hubble Space Telescope finishes 200,000 Earth orbits After more than 36 years in orbit and 1.7 million observations, Hubble continues to explore the universe and provide new insights into the cosmos. Congrats to Hubble! Spaceflight SpaceX's Starship megarocket aces launch rehearsal SpaceX completed a wet dress rehearsal with its Starship megarocket today (Sept. 24), keeping the vehicle on track for a Sept. 28 launch of its first-ever orbital flight. Countdown to launch SpaceX launching prototype Google AI satellite next week A prototype satellite that will test hardware for Google's planned Project Suncatcher AI constellation will launch aboard a SpaceX rocket next week, if all goes to plan. AI satellite? Skywatching Catch Saturn shining beneath the full Harvest Moon Use September's full moon as a guide to spot the ringed planet, then turn a telescope toward two of the night sky's most rewarding sights. Time for a Harvest Moon Science & Astronomy X-ray spacecraft watches dead star feed on a hypergiant Using the X-ray spacecraft XRISM, astronomers have observed stellar winds from a hypermassive star feeding a neutron star. Neutron star for dinner? Black hole 'burps' are always the same Black holes come in a vast array of sizes, from many times the mass of the sun, up to billions of times the size of our star, but the "burps" they emit when feeding seem to be remarkably similar. Burps? Today in Space Lightning crackles within raging Hurricane Polo This is looking like one nasty storm. A terrifying view Entertainment This trippy new 'Star Trek' comic series may be perfect  An imaginative new "Star Trek" comic book dropping this week from IDW Publishing sounds like a seriously suitable candidate for a film adaptation. Feature film, anyone? Editor's Note Editors Note And that's it for our space update today! If you're facing the upcoming Hurricane Polo or the storms on the east coast of the U.S., stay safe this weekend! As the satellites in orbit show us, we've got some serious storms on our hands. If you're stuck inside, however, it might be the perfect time to catch up on your space news. Dive into microquasars, or black hole "burps," or the latest in new spaceflight ventures that seem to get stranger every day. And Saturday night, don't forget to look up and enjoy a beautiful Harvest Moon (maybe even throw on some Neil Young and really lean into the moment).  And next week: mark your calendars for the next Starship launch. With Flight 14, SpaceX aims to put Starship into orbit. And with a successful launch rehearsal now behind them, things are starting to look good. But we will keep you up-to-date as we learn more as the countdown nears launch. And coming up in October, we are now counting down to World Space Week. It's never a dull moment on the final frontier.

На заседании Ученого совета ИТФ в пятницу 25.09 будут заслушаны 2 доклада: 11:30 Андрей Гелаш (Сколковский институт науки и технологий) Численная реализация метода обратной задачи рассеяния для решения задач интегрируемой турбулентности При решении задач интегрируемой турбулентности мы имеем дело с волновыми полями, содержащими сотни солитонов, что делает применение стандартных численных реализаций метода обратной задачи рассеяния невозможным по причине резкого роста численных ошибок. Причины их возникновения при решении прямой и обратной задач рассеяния заключаются в особенностях поведения одного из коэффициентов рассеяния и в необходимости одновременного учета экспоненциально больших и малых величин. Мы разработали серию алгоритмов для интегрируемых моделей НУШ и КдФ, которые используют арифметику высокой точности и таким образом позволяют корректно решать прямую и обратную задачи рассеяния для сотен и тысяч солитонов. 12:30 Андрей Гелаш (Сколковский институт науки и технологий) Стохастизация солитонов конденсата в нелинейном уравнении Шредингера Будет рассмотрена задача о развитии спонтанной модуляционной неустойчивости конденсата в рамках интегрируемой модели нелинейного уравнения Шредингера. Ранее нами было показано, что точные много-солитонные решения с синхронизованными и случайными фазами, описывают начальное состояние конденсата и финальную стадию развития модуляционной неустойчивости соответственно. В данной работе, с точки зрения метода обратной задачи рассеяния, будет рассмотрен вопрос о процессе перехода конденсата из синхронизованного в спонтанное состояние, которое сопровождается стохастизацией солитонного ансамбля. Будут вычислены функции отклика волнового поля в ответ на изменение данных рассеяния солитонов и получена оценка того на каких характерных временах происходит десинхронизация солитонов конденсата.
