📰 Ubuntu Snap Prompting Improvements
If you haven’t tried Ubuntu’s ‘Permission Prompting’ feature for a while, there’s more reason to do so in the latest release. Canonical’s Oliver Calder has shared an update on recent improvements to the security feature, which sets out to “empower users” by letting them decide what software can access on the rest of the system at runtime rather than retrospectively.

🪐 In 2021, astronomers detected a record-breaking gamma-ray burst called GRB 211211A, which defied expectations by lasting over a minute—much longer than most "short" bursts thought to arise from merging neutron stars. Observations with space telescopes revealed this unusually long burst likely came from the merger of two neutron stars in a distant galaxy, showing that cosmic collisions can create gamma-ray explosions with a wider variety of durations and energies than previously believed. ✨

🪐 In December 2004, the galaxy NGC 1637 in the constellation Eridanus was the source of a rare and powerful cosmic event known as a "short gamma-ray burst." Lasting less than two seconds, these bursts are believed to result from the merger of two neutron stars—ultra-dense remnants of massive stars—which create a flash of high-energy gamma rays strong enough to briefly outshine entire galaxies before fading away in moments. ✨

🪐 In April 2023, the Hubble Space Telescope captured the fading afterglow of GRB 230307A, a gamma-ray burst originating over a billion light-years away in the constellation Leo. This colossal explosion was traced to the merger of two neutron stars—super-dense remnants of dead stars—that created not only intense gamma rays but also heavy elements like gold and platinum, revealing the dramatic cosmic origins of some of Earth’s rarest materials. ✨

🪐 The star PSR J0952–0607, about 3,200 light-years away, is the fastest-spinning known pulsar—a type of neutron star that emits beams of radiation—as it completes over 707 rotations every single second. This "black widow" pulsar is slowly destroying its companion star with powerful radiation, a cosmic process that leaves behind only the densest, most compact remnant. ✨

🚀У SpaceX появился реальный конкурент!
Rocket Lab почти достроила свою "Starbase" для ракеты Neutron🌍🛰
Стартовый комплекс Launch Complex 3 на побережье в Mid-Atlantic Regional Spaceport (NASA Wallops, США) практически готов. Уже начата поэтапная активация систем перед испытаниями, а официальное открытие намечено на следующий месяц. 📆
📡 По снимкам видно:
— высокая стартовая башня
— минимум один стартовый стол
— инфраструктура для тестов и запусков
🧪 Ракета Neutron:
🔹 до 15 000 кг — в одноразовом варианте
🔹 до 8 000 кг — с возвращаемой ступенью
🔁 Rocket Lab прорабатывает возврат первой ступени — в духе SpaceX
💬 Вопрос, «строит ли Rocket Lab свой Starbase», остаётся открытым. Но LC-3 уже выглядит как стратегическая база многоразовых запусков, что явно указывает на большие амбиции компании. Первый запуск Neutron может стать переломным моментом в мировой космической гонке 🌌🔥
