APOD: 2025 March 18 B LDN 1235: The Shark Nebula
17.03.2025 | Astronomicheskaya kartinka dnya

There is no sea on Earth large enough to contain the Shark nebula. This predator apparition poses us no danger as it is composed only of interstellar gas and dust. Dark dust like that featured here is somewhat like cigarette smoke and created in the cool atmospheres of giant stars.

U Tora est' ne tol'ko sobstvennyi den' nedeli – chetverg (Thor – Thursday), no i shlem v nebesah. NGC 2359 – imeyushee formu shlema kosmicheskoe oblako s pohozhimi na kryl'ya pridatkami, kotoroe obychno nazyvayut Shlemom Tora. Razmer Shlema Tora dostigaet 30 svetovyh let – dazhe skandinavskomu bogu on ne pokazhetsya malen'kim.

Eto bylo neobychnoe solnechnoe zatmenie. Obychno Solnce zatmevaetsya sputnikom Zemli – Lunoi. Odnako v iyune 2012 goda nastupila ochered' planety Venera. Kak i pri solnechnom zatmenii Lunoi, pri priblizhenii Venery k Solncu ona byla vidna kak vse bolee tonkii polumesyac. Nakonec, ih polozheniya na nebe sovpali, i faza Venery stala ravna nulyu.

Polnoe zatmenie nad Serro-Tololo

14 marta nastupilo polnolunie. Po udachnomu sovpadeniyu v den' chisla π rasstoyanie ot Luny do Solnca po eklipticheskoi dolgote na nebe planety Zemlya sostavilo 3.14 radianov (180 gradusov). Eshe odnim syurprizom dlya lyubitelei chisla π i nochnogo neba stalo to, chto Luna proshla pryamo skvoz' temnuyu chast' zemnoi teni – proizoshlo polnoe lunnoe zatmenie.

Kakaya faza u Luny, esli ee rasstoyanie ot Solnca – 3.14 radianov? Konechno, eto polnaya Luna. Hotya Luna kazhetsya polnoi v techenie neskol'kih dnei, nastoyashee polnolunie nastupaet, kogda rasstoyanie ot Luny do Solnca po eklipticheskoi dolgote sostavlyaet 3.14 radianov (ili 180 gradusov). Eto – protivopolozhnaya Solncu tochka na nebe planety Zemlya.

Protozvezdy vnutri Linds 483
12.03.2025 | Astronomicheskaya kartinka dnya

Dve protozvezdy spryatalis' v odnom piksele okolo centra effektnoi tumannosti v forme pesochnyh chasov na etom izobrazhenii, poluchennom Kosmicheskim teleskopom "Dzheims Vebb" v blizhnem infrakrasnom diapazone. Aktivno formiruyushayasya zvezdnaya sistema raspolozhena v bogatom pyl'yu molekulyarnom oblake, zanesennom v katalog kak Linds 483, nahodyashemsya na rasstoyanii okolo 650 svetovyh let v sozvezdii Zmei (v ee "hvoste").

11.03.2025 | Astronomicheskaya kartinka dnya

Pochemu eta galaktika pohozha na zakruchennyi pobeg paporotnika? Veroyatno, iskazhennyi vid spiral'noi galaktiki Paporotnik voznik iz-za gravitacionnogo vzaimodeistviya s blizkoi ellipticheskoi galaktikoi NGC 770, kotoraya vidna nizhe. Galaktika Paporotnik zanesena v katalogi...

Spiral'naya galaktika s peremychkoi NGC 1672: vid v teleskop im.Habbla
10.03.2025 | Astronomicheskaya kartinka dnya

U mnogih galaktik okolo centrov est' peremychki. Predpolagaetsya, chto dazhe u nashei Galaktiki Mlechnyi Put' est' nebol'shaya central'naya peremychka. Effektnye detali struktury spiral'noi galaktiki s horosho zametnoi peremychkoi NGC 1672 zapechatleny na etom izobrazhenii, poluchennom orbital'nym kosmicheskim teleskopom im.Habbla.

NGC 1499: tumannost' Kaliforniya

Mog li mificheskii ostrov korolevy Kalafii sushestvovat' v kosmose? Skoree vsego net, no po chistoi sluchainosti ochertaniya etogo kosmicheskogo molekulyarnogo oblaka pohozhi na beregovuyu liniyu shtata Kaliforniya v SShA. Nashe Solnce nahoditsya v rukave Oriona Mlechnogo Puti, vsego v tysyache svetovyh let ot tumannosti Kaliforniya.

Ciklony na severnom polyuse Yupitera
8.03.2025 | Astronomicheskaya kartinka dnya

Pochemu vokrug severnogo polyusa Yupitera tak mnogo ciklonov? Etot vopros yavlyaetsya predmetom issledovanii. Avtomaticheskii kosmicheskii apparat NASA "Yunona", obrashayushiisya vokrug Yupitera, v 2018 godu poluchil dannye, ispol'zovannye dlya sozdaniya etogo effektnogo izobrazheniya ciklonov na severnom polyuse Yupitera. Infrakrasnye nablyudeniya, registriruyushie teplovoe izluchenie ot vershin oblakov, ne ogranichivayutsya polushariem, osveshennym solnechnym svetom.
