Poyasnenie:
Zdes' pokazana odna galaktika ili dve?
Kazhetsya, chto galaktika tol'ko odna, odnako pravil'nyi otvet – dve.
Takaya kartina mozhet nablyudat'sya, kogda malen'kaya
galaktika
stalkivaetsya s bol'shoi i okazyvaetsya
v ee centre.
Odnako v
etom sluchae
proishodit gorazdo
bolee redkoe yavlenie.
Central'naya bolee svetlaya
ellipticheskaya galaktika
gorazdo blizhe, chem okruzhayushaya ee okrashennaya v goluboi i krasnyi cveta
spiral'naya galaktika.
Kogda blizkaya i dalekaya galaktiki nahodyatsya tochno
na odnom luche zreniya,
gravitaciya blizkoi galaktiki iskrivlyaet svet, idushii ot dalekoi galaktiki. Etot
effekt nazyvaetsya
gravitacionnym linzirovaniem.
Izobrazhenie
etoi pary galaktik
bylo polucheno
Kosmicheskim teleskopom "Dzheims Vebb",
na nem zapechatleno polnoe
kol'co Einshteina
i detali struktury galaktik.
Issledovanie
podobnyh gravitacionnyh linz
mozhet dat' novye dannye o
raspredelenii massy
v blizkoi galaktike i o
raspredelenii svetyashegosya veshestva
v dalekom istochnike.
