Неописуемая красота космоса: лучшие фото НАСА в Instagram

Фото: nasa, instagram.com

Космос всегда манил человека своей загадочностью и величием. Наше сознание отказывается воспринимать те расстояния, которые отделяют нас от других небесных тел. Более того, мы даже не можем представить себе те мириады галактик, которые существуют где-то там в бесконечности. Но это не мешает нам наслаждаться красотой космоса. Intex-press выбрала лучшие фотографии, опубликованные НАСА в Instagram.

Национальное управление по аэронавтике и исследованию космического пространства (NASA) — ведомство, относящееся к федеральному правительству США и подчиняющееся непосредственно вице-президенту США. Ответственно за гражданскую космическую программу страны, а также за научные исследования воздушного и космического пространств и научно-технологические исследования в области авиации, воздухоплавания и космонавтики. НАСА является обладателем самой фантастической коллекции снимков Земли и небесных тел из космоса.

Behold, two spiral galaxies! Astronomers used the Hubble Space Telescope to take a portrait of a stunning pair of spiral galaxies. This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer. These galaxies look quite different because we see them angled at different positions on the sky. They are actually very similar in terms of their structure and contents.` Both galaxies are approximately 55 million light-years away and reside in a cluster of nearly 2,000 galaxies. A typical spiral galaxy has arms of young stars that wind outward from its center. The bright arms are regions of intense star formation. Such galaxies have a central bulge and are surrounded by a faint halo of stars. Many spiral galaxies also have bars that extend from the central bulge to the arms. Credits: NASA, ESA, and M.

Две спиральные галактики: NGC 4302, NGC 4298. NGC 4302 составляет около 87 000 световых лет в диаметре (около 60% от диаметра Млечного Пути) и обладает массой около 110 миллиардов солнц (около 10% массы нашей Галактики); NGC 4298 составляет около 45 000 световых лет в диаметре и обладает массой около 17 миллиардов солнц.

This galaxy is a whirl of color! Bursts of blue throughout the spiral arms are regions filled with young stars glowing brightly in ultraviolet light, while redder areas are filled with older stars emitting in the cooler near-infrared. But there is more in this galaxy than meets the eye. At 150 million light-years from Earth, astronomers using the Hubble Space Telescope (@NASAHubble) highlighted NGC 6753 as one of only two known spiral galaxies that are both massive enough and close enough to make detailed observations of their coronas. Galactic coronas are huge, invisible regions of hot gas that surround a galaxy’s visible bulk, forming a spheroidal shape. Coronas are so hot that they can be detected by their X-ray emission, far beyond the optical radius of the galaxy. Because they are so wispy, these coronas are extremely difficult to detect.

NGC 6753 (другие обозначения — PGC 62870, ESO 184-22, AM 1907-570, IRAS19071-5707) — спиральная галактика расположенная в созвездии Павлин. Она находится на расстоянии 150 миллионов световых лет от Земли. Астрономы при помощи телескопа Хаббл смогли подсветить NGC 6753 и получить эти яркие фотографии.

Far, far away…55 million light-years to be exact, lies this galaxy containing a massive star-forming cloud. This large cloud composed of ionized hydrogen is the only massive star-forming complex in the entire galaxy. Imaged by the Hubble Space Telescope (@nasahubble), this barred spiral galaxy is famous for containing an especially extensive HII region, a large cloud composed of ionized hydrogen (or HII, pronounced “H=two,” with H being the chemical symbol for hydrogen and the “II” indicating that the atoms have lost an electron to become ionized). This cloud sits at the lower left end of the galaxy’s central “bar” of stars, a structure that cuts through the galactic core and funnels material inwards to maintain the star formation occurring there.

Like firecrackers lighting up the sky on New Year’s Eve, the majestic spiral arms of this galaxy are alight with new stars being born. The Hubble Space Telescope (@NASAHubble) saw this spiral galaxy, NGC 5559, with spiral arms filled with gas and dust sweeping out around the bright galactic bulge. These arms are a rich environment for star formation, dotted with a festive array of colors including the newborn stars glowing blue as a result of their immensely high temperatures. NGC 5559 was discovered by astronomer William Herschel in 1785 and lies approximately 240 million light-years away in the northern constellation of Boötes (the herdsman).

NGC 5559 (другие обозначения — UGC 9166, MCG 4-34-17, ZWG 133.32, IRAS14169+2501, PGC 51155) — спиральная галактика с перемычкой (SBb) в созвездии Волопас.

One of the two galaxies seen here by the Hubble Space Telescope (@nasahubble) is emitting the same microwaves as your kitchen appliance. Microwaves are actually produced by a multitude of astrophysical sources, including strong emitters known as masers (microwave lasers), even stronger emitters with the somewhat villainous name of megamasers and the centers of some galaxies. The lower, blue-tinted galaxy is a special kind of megamaser. The galaxy’s active galaxtic nucleus pumps out huge amounts of energy, which stimulates clouds of surrounding water. Water’s constituent atoms of hydrogen and oxygen are able to absorb some of this energy and re-emit it at specific wavelengths, one of which falls within the microwave regime.

Две галактики, расположенные на расстоянии около 400 миллионов световых лет от Млечного пути. Вверху расположена MCG+01-38-004, внизу — MCG+01-38-005, также известная как NGC 5765B. Последняя галактика является мегамазером. Так называют объекты, излучающие микроволны.

Gravity governs the movements of the cosmos. It can even bring galaxies so close that they begin to tug at one another, causing them to abandon their former identities and merge to form a single accumulation of gas, dust and stars. In this Hubble Space Telescope image is one such interaction where a galaxy called IC 1727 is currently interacting with its near neighbor galaxy, NGC 672 (which is just out of frame). The pair’s interactions have triggered peculiar and intriguing phenomena within both objects — most noticeably in IC 1727. The galaxy’s structure is visibly twisted and asymmetric, and its bright nucleus has been dragged off-center. In interacting galaxies such as these, astronomers often see signs of intense star formation (in episodic flurries known as starbursts) and spot newly-formed star clusters. They are thought to be caused by gravity churning, redistributing and compacting the gas and dust. In fact, astronomers have analyzed the star formation within IC 1727 and NGC 672 and discovered something interesting — observations show that simultaneous bursts of star formation occurred in both galaxies some 20 to 30 and 450 to 750 million years ago. The most likely explanation for this is that the galaxies are indeed an interacting pair, approaching each other every so often and swirling up gas and dust as they pass close by.

Wispy arms swirling out from a bright, elongated core distinguish a particular kind of spiral galaxy known as a barred spiral, seen here in this Hubble Space Telescope image. Residing about 30 million light-years away in the northern constellation of Lynx, this galaxy was first discovered by British astronomer William Herschel over 200 years ago. Barred spirals are actually more common than was once thought. Around two-thirds of all spiral galaxies – including the Milky Way – exhibit these straight bars cutting through their centers. These cosmic structures act as glowing nurseries for newborn stars, and funnel material towards the active core of a galaxy. This galaxy is still actively forming new stars, although this process appears to be occurring very unevenly. The upper half of the galaxy – where the spiral arms are slightly better defined – hosts many more star-forming regions than the lower half, as indicated by the bright, dotted islands of light.

Галактика NGC 2500 лежит на расстоянии примерно 30 миллионов световых лет от нас в северном созвездии Рысь. NGC 2500 относится к особому классу спиральных галактик, известному как спиральные галактики с перемычкой, спиральные рукава которых раскручиваются из яркой, вытянутой центральной части.

Hubble sees a force awakening in a newborn star…What looks like a double-sided lightsaber is actually a cosmic object known as HH 24. This celestial lightsaber does not lie in a galaxy far, far away, but rather inside our home galaxy, the Milky Way. It's inside a turbulent birthing ground for new stars known as the Orion B molecular cloud complex, located 1,350 light-years away. Just to the right of the cloaked star, a couple of bright points are young stars peeking through and showing off their own faint lightsabers — including one that has bored a tunnel through the cloud towards the upper-right side of the picture.

Звезда-меч HH 24 на снимке имеет в своем арсенале две светящиеся линейки. Ученые сравнили их с мечом героев из фантастической саги «Звездные войны». Удивителен и тот факт, что на сегодняшний момент звезда все еще зарождается. Она старается максимально напитаться газом, собирая его из окружающей среды.

Galaxy 2XMM J143450.5+033843's name is not a random jumble of numbers and letters. This galaxy, imaged by the Hubble Space Telescope, was detected and observed as part of the second X-ray sky survey performed by the XMM-Newton Observatory. Its celestial coordinates form the rest of the bulky name, following the “J”: a right ascension value of 14h (hours) 34m (minutes) 50.5s (seconds). This can be likened to terrestrial longitude. It also has a declination of +03d (degrees) 38m (minutes) 43s (seconds). Declination can be likened to terrestrial latitude. This galaxy lies nearly 400 million light-years away from Earth. It is a Seyfert galaxy that is dominated by something known as an Active Galactic Nucleus – meaning its core is thought to contain a supermassive black hole that is emitting huge amounts of radiation, pouring energetic X-rays out into the Universe.

Галактика 2XMM J143450.5+033843 находится на расстоянии 400 миллионов световых лет от Земли. Она является Сейфертовской галактикой, которая обладает центральным объектом под названием активное ядро галактики (АЯГ). Такие ядра, как предполагают современные астрономы, содержат в себе сверхмассивную черную дыру, которая испускает огромное количество излучения, выбрасывая энергетически сильные рентгеновские лучи во Вселенную.

A maelstrom of glowing gas and dark dust within one of the Milky Way's satellite galaxies, the Large Magellanic Cloud (LMC), captured by the Hubble Space Telescope. This stormy scene shows a stellar nursery that's over 150 light-years across. It contains many hot young stars. These stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stellar winds, which are carving out ridges, arcs, and filaments from the surrounding material. At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. This small, dense object is thought to be tightly linked to the early stages of massive star formation.

Водоворот светящегося газа и темной пыли или звездный питомник N159, простирающийся примерно на 150 световых лет. Туманность содержит огромное количество горячих молодых звезд, которые, испуская интенсивное ультрафиолетовое излучение, заставляют светиться близлежащий газообразный водород.

NGC 6537 — планетарная туманность состоит из двух симметричных взаимопроникающих структур и содержит один из самых горячих известных белых карликов, входящий, вероятно в состав двойной звездной системы. Скорость внутренних ветров, истекающих со звезд в центре системы, согласно проведенным измерениям превышает тысячу километров в секунду. Эти ветры заставляют туманность расширяться и приводят к столкновениям волн горячего газа и пыли.
