  8. Смерть Сонця не буде вибуховою чи миттєвою. На відміну від масивних зірок, воно не перетвориться на наднову. Його фінал — це повільний космічний процес, що триватиме мільярди років і завершиться народженням білого, а згодом і чорного карлика.

    ☀ Через приблизно 5 мільярдів років Сонце вичерпає запаси водню в ядрі. Після цього ядро почне стискатися, а зовнішні шари — стрімко розширюватися. Зірка збільшиться майже у 200 разів і стане Червоним гігантом. Меркурій і Венера будуть поглинуті, а Земля, найімовірніше, також зникне або перетвориться на розпечений світ із поверхнею, вкритою океанами лави.

    🔥 Коли температура ядра досягне близько 100 мільйонів градусів, розпочнеться горіння гелію з утворенням вуглецю та кисню. Цей етап буде нестабільним: Сонце почне пульсувати та втрачати свої зовнішні оболонки під дією потужних зоряних вітрів.

    🌌 Згодом скинутий газ утворить планетарну туманність — одну з найкрасивіших космічних структур. Протягом десятків тисяч років вона світитиметься завдяки випромінюванню гарячого ядра, а потім поступово розчиниться в міжзоряному просторі, збагативши його елементами, з яких колись сформуються нові зорі та планети.

    ⭐ У центрі залишиться білий карлик — надщільне ядро розміром із Землю, але з масою приблизно половини сучасного Сонця. Термоядерні реакції в ньому вже припиняться, і він світитиметься лише за рахунок накопиченого тепла. Навіть невеликий шматочок його речовини мав би на Землі колосальну масу через надзвичайну щільність.

    🌑 Через трильйони років білий карлик остаточно охолоне й перетвориться на чорного карлика — холодний, темний і майже невидимий залишок колишньої зірки. Саме так завершиться історія Сонця — не вибухом, а повільним згасанням.

  12. 💁🏻‍♀️ TIL: ☀️🌍 For decades, scientists assumed #Earth would spiral into the #Sun when it swells into a red giant billions of years from now.

    A new study flips that prediction. Better modeling of tidal dissipation inside dying #stars finds that the Sun’s mass loss from stellar wind may push Earth outward, potentially saving it from incineration.

  22. Sulla fine degli #Anni90 in un viaggio in Scozia, iniziai a collezionare #Warhammer40000
    All’epoca volevo dipingere “bene” per me stesso, mettermi in paragone con le foto che trovavo sulla rivista #WhiteDwarf o, al limite, confrontarmi coi miei amici - rari - appassionati.
    Era un vero #hobby nel senso stretto della parola, un senso che oggi dobbiamo ritrovare più che mai, in TUTTO.
    Torniamo a fare le cose per noi, per il nostro gusto, non per il performativismo forzato: io ci sto provando.

  34. Speaking of D&D classes, and magazines, and specifically White Dwarf. In Issue 35, they presented a Necromancer class. Then in Issue 36, someone presented some follow up spell abilities for the class.

    Want to know who wrote these abilities in 1982?

  39. Eternal ponderings. D&D did not have perception as an ability score.

    In my homebrew, I added perception.

    Come to find out, such quandaries were happening since the beginning. In White Dwarf Magazine Issue 17 published February 1980, Barney Sloane proposed the same idea.
