Pesok vremeni pochti zakonchilsya dlya
central'noi zvezdy etoi
planetarnoi tumannosti
v forme pesochnyh
chasov.
Vse yadernoe toplivo v centre etoi zvezdy,
pohozhei na
Solnce, uzhe ischerpano. Teper' ona perehodit v korotkuyu, no zrelishnuyu zaklyuchitel'nuyu
fazu
svoei zhizni,
sbrasyvaya vneshnie sloi obolochki i prevrashayas' v ostyvayushii i ugasayushii
belyi karlik.
