Boeing plans to lay off hundreds of SLS employees: reports

Boeing is preparing to issue layoff notices to roughly 200 employees working on the Space Launch System (SLS) - the massive rocket central to NASA's flagship Artemis program - as it braces for the possibility that its contracts with the space agency may not be renewed after they end in March.

Space Quiz! What year was Pluto discovered?

Our love for Pluto is stronger than ever 95 years later

Clyde Tombaugh didn't set out to discover Pluto when he sent his sketches of the night sky to Lowell Observatory in 1929. Tombaugh sent his drawings, unsolicited, to several institutions and observatories around the US, hoping someone would give him some feedback. The response from Lowell Observatory, then, must have been a shock when it hit his mailbox. It was a job offer (from the head of the Observatory, no less), and one that within two years would put Tombaugh in an elite and narrow pantheon of stargazers who could claim what only the ancients could boast: the discovery of a new planet.

7 planets are aligned in the night sky right now

For the last month and change, you might've seen the headlines about the planetary alignment, or a planetary parade, going on in our solar system. And that's true. In January 2025, Venus, Mars, Jupiter, Saturn, Uranus and Neptune were all visible in the night sky. And in February, 2025, Mercury will join the fun, with all seven of our planetary neighbors visible from Earth.

Japan's Resilience moon lander aces lunar flyby

The private Resilience lunar lander just got its first up-close look at the moon. Resilience, which was built by Japanese company ispace, aced a flyby of the moon on Friday evening (Feb. 14), coming within a mere 5,220 miles (8,400 kilometers) of Earth's nearest neighbor. The lander memorialized the milestone with a photo, snapping a nice shot of the battered lunar surface from a distance of 8,972 miles (14,439 km).

JWST finds our galaxy's black hole blowing bubbles

The black hole at the heart of our galaxy is a real party animal, endlessly blowing cosmic bubbles. The findings aren't frivolous at all and could help us better understand how black holes interact with their environments and help galaxies evolve.

Starlink mission lands 1st rocket off coast of The Bahamas

SpaceX broke new ground during its Starlink internet satellite launch yestereday (Feb. 18). The rocket's first stage made its descent back to Earth eight minutes after liftoff, landing on the droneship Just Read the Instructions, stationed in the Atlantic Ocean off the coast of The Bahamas. SpaceX has traditionally parked its droneships in the open ocean, but it recently signed a deal with The Bahamas that will open new opportunities to the company.

Search for Life

I want to believe - but yet another massive search for alien technosignatures just turned up nothing

Hunting for alien civilizations isn't a matter of just waiting around for them to show up; it's the business of combing through enormous volumes of data to look for peculiar signals. The good news is that astronomers have developed an efficient method for doing exactly this. The bad news is that they haven't found anything … yet.

Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 21.02 в 11:30 будет заслушан 1
доклад:

О корректности постановки задачи моделирования кинетического уравнения
для капиллярных волн.

А.О. Короткевич

В последнее время в литературе часто обсуждается проблема корректности
постановки задачи описания взаимодействия волн в рамках кинетического
уравнения для различных моделей. В данной работе рассматривается
кинетическое уравнение для капиллярных волн на поверхности жидкости.
Понимая, что полное доказательство корректности постановки задачи через
численный эксперимент невозможно, рассматриваются результаты ряда
численных экспериментов, подобных выполненным в недавней работе
arXiv:2109.02477 (Phys. Rev. Lett., vol. 129, p. 034101 (2022)).
Показано, что если правильно учесть скелинги параметров в кинетическом
уравнении, то результаты полностью совпадают. Это означает, что как
минимум при таком диапазоне параметров численный эксперимент
качественно, а, скорее всего, и количественно, описывается кинетическим
уравнение для капиллярных волн.
