... Пояснение: Это плывущее в космосе кольцо размером с галактику является частью великолепной галактики Сомбреро , одной из самых больших, входящей в состав скопления галактик в Деве . Темная полоса пыли , затмевающая среднюю часть галактики Сомбреро в оптическом диапазоне, является более яркой в ИК-области. ... Галактика Сомбреро , известная также как M104, имеет размеры 50 тысяч световых лет и находится на расстоянии 28 миллионов световых лет от Солнца. ... Близкая спиральная галактика NGC 4945 . ...

It is shown that the fast rotation of nuclear gaseous disks makes them gravitationally stable or marginally unstable. ... Nuclear disks are usually distinguished by high angular velocity of gas. ...
