Получено изображение поверхности красного гиганта. Р золотой рыбы - это созвездие Южного полушария.

Что интересно в этой новости? Сейчас вы увидите картинку, которую они получили, и даже фильм таймлапс, который на основании этой картинки сделан. Вот вы сейчас его видите.

Что происходит? Мы видим глазами появление на поверхности красного гиганта грануляции. Но эта грануляция - это грануляция в огромных масштабах.

Что это, в общем-то, такое? Это конвективные потоки, которые идут из недр звезды и вызывают на поверхности звезды вот такую рябь. Это явление нам известно на солнце.

Но солнце, поскольку само по себе, гораздо меньше. Между прочим, эта звезда имеет примерно солнечную массу, но приблизительно в 500 раз больше солнца по диаметру.
