Poyasnenie:
Chto proishodit, kogda u zvezdy zakanchivaetsya
yadernoe toplivo?
U zvezd, pohozhih na nashe
Solnce, yadro szhimaetsya i stanovitsya
belym karlikom,
a vneshnyaya atmosfera vybrasyvaetsya v kosmicheskoe prostranstvo i vyglyadit kak
planetarnaya tumannost'.
Vybroshennaya atmosfera, stavshaya planetarnoi tumannost'yu
NGC 1514,
v
vidimom svete
vyglyadit kak
besporyadochnaya smes' puzyrei.
Odnako
izobrazhenie, poluchennoe
Kosmicheskim teleskopom "Dzheims Vebb" v
infrakrasnom
diapazone,
otchetlivo pokazyvaet formu, pohozhuyu na
pesochnye chasy.
Etu kartinu mozhno
interpretirovat' kak
cilindr,
na kotoryi my smotrim vdol' diagonali.
Vnimatel'no posmotrev na centr tumannosti, vy uvidite
yarkuyu central'nuyu zvezdu, vhodyashuyu v sostav
dvoinoi sistemy.
Dal'neishie nablyudeniya mogut pomoch' luchshe ponyat', kak central'nye zvezdy vmeste
sozdayut
vidimye formy cilindra i puzyrei.
