STARFORGE: modelirovanie zvezdoobrazovaniya APOD STARFORGE: modelirovanie zvezdoobrazovaniya
23.06.2021 | Astronomicheskaya kartinka dnya

Kak formiruyutsya zvezdy? Bol'shinstvo zvezd formiruetsya v gigantskih molekulyarnyh oblakah, raspolozhennyh v central'nom diske galaktiki. Na processy vliyayut zvezdnye vetry, dzhety, moshnoe izluchenie zvezd i vzryvy ranee sushestvovavshih zvezd kak sverhnovye. Eti yavleniya obuslovlivayut nachalo i prekrashenie zvezdoobrazovaniya. Eto video demonstriruet slozhnye vzaimodeistviya processov.


HD 163296: dzhet ot formiruyusheisya zvezdy APOD HD 163296: dzhet ot formiruyusheisya zvezdy
22.06.2021 | Astronomicheskaya kartinka dnya

Kak obrazuyutsya dzhety u formiruyusheisya zvezdy? Okonchatel'nogo otveta poka net, odnako nedavno poluchennye izobrazheniya molodoi zvezdnoi sistemy HD 163296 mogut dat' novuyu poleznuyu informaciyu. Central'naya zvezda na etoi kartinke vse eshe formiruetsya, odnako ona uzhe okruzhena vrashayushimsya diskom i vybrasyvaet dzhet.


Animaciya: chernaya dyra razrushaet zvezdu APOD Animaciya: chernaya dyra razrushaet zvezdu
27.04.2021 | Astronomicheskaya kartinka dnya

Chto proizoidet, esli zvezda priblizitsya k chernoi dyre? Chernaya dyra smozhet razorvat' ee – no kak? Razrushaet zvezdu ne samo sil'noe gravitacionnoe prityazhenie, a razlichie gravitacionnyh sil vnutri zvezdy. Eto video demonstriruet process razrusheniya.


Iskrivlennye magnitnye polya Centavra A APOD Iskrivlennye magnitnye polya Centavra A
21.04.2021 | Astronomicheskaya kartinka dnya

Kogda galaktiki stalkivayutsya, chto proishodit s ih magnitnymi polyami? Chtoby popytat'sya vyyasnit' eto, NASA ispol'zovalo letayushuyu na samolete Boing-747 observatoriyu SOFIA. Ona nablyudala polyarizovannoe izluchenie pyli, kotoroe pozvolyaet ustanovit' napravlenie magnitnogo polya, v sosednei galaktike Centavr A.


Dvazhdy iskrivlennyi mir dvoinyh chernyh dyr APOD Dvazhdy iskrivlennyi mir dvoinyh chernyh dyr
16.04.2021 | Astronomicheskaya kartinka dnya

Luchi sveta ot akkrecionnyh diskov vokrug pary obrashayushihsya vokrug obshego centra tyazhesti sverhmassivnyh chernyh dyr prohodyat skvoz' iskrivlennoe ih ekstremal'noi gravitaciei prostranstvo-vremya. Na etoi komp'yuternoi vizualizacii smodelirovannye akkrecionnye diski okrasheny v raznye cveta &ndash...


Galaktika, dzhet i znamenitaya chernaya dyra APOD Galaktika, dzhet i znamenitaya chernaya dyra
15.04.2021 | Astronomicheskaya kartinka dnya

V yarkoi ellipticheskoi galaktike Mess'e 87 (M87) nahoditsya sverhmassivnaya chernaya dyra, izobrazhenie kotoroi vpervye polucheno na planete Zemlya Teleskopom gorizonta sobytii. Gigantskaya galaktika raspolozhena v skoplenii galaktik v Deve, udalennom ot nas na 55 millionov svetovyh let. Na infrakrasnom izobrazhenii, poluchennom kosmicheskim teleskopom im.Spitcera, M87 okrashena v golubye ottenki.


Podtverzhdennaya precessiya myuonov ostaetsya neob'yasnimoi APOD Podtverzhdennaya precessiya myuonov ostaetsya neob'yasnimoi
13.04.2021 | Astronomicheskaya kartinka dnya

Kak bystro precessiruyut elementarnye chasticy? Neozhidannyi otvet na etot kazhushiisya nelogichnym vopros byl poluchen v Brukheivenskoi Nacional'noi Laboratorii v shtate N'yu-'ork v SShA v 2001 godu. On pokazal, chto prinyataya v fizike elementarnyh chastic standartnaya model' nepolna. V osobennosti eto otnositsya k myuonu – chastice, pohozhei na tyazhelyi elektron.


Kogda stalkivayutsya chernye dyry APOD Kogda stalkivayutsya chernye dyry
11.04.2021 | Astronomicheskaya kartinka dnya

Chto proishodit, kogda stalkivayutsya dve chernye dyry? Podobnaya isklyuchitel'naya situaciya mozhet osushestvlyat'sya, naprimer, v yadrah stalkivayushihsya galaktik ili v kratnyh zvezdnyh sistemah. Eto video pokazyvaet komp'yuternuyu animaciyu podobnogo stolknoveniya, osobenno podcherkivaya effekty gravitacionnogo linzirovaniya, kotorye mozhno obnaruzhit' po nablyudeniyam dalekih zvezd.


Central'naya chernaya dyra v M87 v polyarizovannom svete APOD Central'naya chernaya dyra v M87 v polyarizovannom svete
31.03.2021 | Astronomicheskaya kartinka dnya

"Esli vy hotite poluchit' dzhety ot chernoi dyry, vy dolzhny snachala sozdat' magnitnye polya" – eto znamenitoe vyskazyvanie Karla Sagana. Eto izobrazhenie pokazyvaet obnaruzhennoe napravlenie vnutrennego vrasheniya (polyarizacii) radiovoln. Polyarizaciya sozdaetsya moshnym magnitnym polem, okruzhayushim sverhmassivnuyu chernuyu dyru v centre ellipticheskoi galaktiki M87.


Vspyshki pul'sara v Krabe APOD Vspyshki pul'sara v Krabe
9.02.2021 | Astronomicheskaya kartinka dnya

On smog perezhit' vzryv, kotoryi navernyaka razrushil by nashe Solnce. Seichas on vrashaetsya so skorost'yu 30 oborotov v sekundu i izvesten svoimi bystrymi vspyshkami. Eto – pul'sar v Krabe – vrashayushayasya neitronnaya zvezda, ostatok sverhnovoi, sozdavshei Krabovidnuyu tumannost'. Vnimatel'no posmotrev eto video, vy obnaruzhite vspyshki pul'sara nemnogo vyshe centra kartinki.
