Каждый день NASA публикует на своем сайте фотографию космического объекта с кратким описанием, выполненным астрономом. Однако гораздо удобнее следить за рубрикой Astronomy Picture of the Day в Instagram. Невероятные фотографии галактик, инопланетных ландшафтов, метеорных потоков и необычных атмосферных явлений — страницу @astronomypicturesdaily стоит пролистать не только для того, чтобы расширить познания в астрономии, но и чтобы просто расслабиться.
Посмотреть эту публикацию в Instagram If you go high enough, you may find yourself on a picturesque perch between the water clouds of the Earth and the star clouds of the Milky Way. Such was the case last month for one adventurous alpinist astrophotographer. Captured here in the foreground above white clouds are mountain peaks in the Dolomite range in northern Italy. This multi-exposure image was captured from Lagazuoi, one of the Dolomites. Hundreds of millions of years ago, the Dolomites were not mountains but islands an ancient sea that rose through colliding tectonic plates. The Dolomites divergent history accounts for its unusually contrasting features, which include jagged crests and ancient marine fossils. High above even the Dolomites, and far in the distance, dark dust lanes streak out from the central plane of our Milky Way Galaxy. The stars and dust are dotted with bright red clouds of glowing hydrogen gas — such as the Lagoon Nebula just above and to the left of center.

Посмотреть эту публикацию в Instagram What kind of clouds are these? Although their cause is presently unknown, such unusual atmospheric structures, as menacing as they might seem, do not appear to be harbingers of meteorological doom. Formally recognized as a distinct cloud type only last year, Asperitas clouds can be stunning in appearance, unusual in occurrence, and are relatively unstudied. Whereas most low cloud decks are flat bottomed, asperitas clouds appear to have significant vertical structure underneath. Speculation therefore holds that asperitas clouds might be related to lenticular clouds that form near mountains, or mammatus clouds associated with thunderstorms, or perhaps a foehn wind — a type of dry downward wind that flows off mountains. Such a wind called the Canterbury arch streams toward the east coast of New Zealand’s South Island. The featured image, taken above Hanmer Springs in Canterbury, New Zealand, in 2005, shows great detail partly because sunlight illuminates the undulating clouds from the side.

Посмотреть эту публикацию в Instagram M100: A Grand Design Spiral Galaxy Image Credit: NASA, ESA, Hubble Explanation: Majestic on a truly cosmic scale, M100 is appropriately known as a grand design spiral galaxy. It is a large galaxy of over 100 billion stars with well-defined spiral arms that is similar to our own Milky Way Galaxy. One of the brightest members of the Virgo Cluster of galaxies, M100 (alias NGC 4321) is 56 million light-years distant toward the constellation of Berenice’s Hair (Coma Berenices). This Hubble Space Telescope image of M100 was taken recently with the Wide Field Camera 3 and accentuates bright blue star clusters and intricate winding dust lanes which are hallmarks of this class of galaxies. Studies of variable stars in M100 have played an important role in determining the size and age of the Universe.

Посмотреть эту публикацию в Instagram A Cold December Night Image Credit & Copyright: Petr Horálek Explanation: They say Orion always comes up sideways, and he does seem to on this cold December night. The bright stars of the familiar northern winter constellation lie just above the snowy tree tops surrounding a cozy cottage near the town of Ustupky in the Czech Republic. But Gemini’s meteors also seem to rain on the wintry landscape. The meteor streaks are captured in exposures made near last Friday’s peak of the annual Geminid meteor shower. They stream away from the shower’s radiant above the trees, near the two bright stars of the zodiacal constellation of the Twins. Comet Wirtanen, a visitor to planet Earth’s skies, is visible too. Look for its telltale greenish coma near the stars of the seven sisters. Публикация от Astronomy Picture Of The Day (@astronomypicturesdaily) 22 Дек 2018 в 6:21 PST
Посмотреть эту публикацию в Instagram Swimming on Jupiter Image Credit: NASA, JPL-Caltech, SwRI, MSSS; Processing: Brian Swift, Sean Doran Explanation: On October 29, the Juno spacecraft once again dove near the turbulent Jovian cloud tops. Its 16th orbital closest approach or perijove passage, brought Juno within 3,500 kilometers of the Solar System’s largest planetary atmosphere. These frames, recorded by JunoCam while the spacecraft cruised 20 — 50 thousand kilometers above the planet’s middle southern latitudes, seem to follow a swirling cloud shaped remarkably like a dolphin. Swimming along Jupiter’s darker South South Temperate Belt, this dolphin is itself planet-sized though, some thousands of kilometers across. Juno’s next perijove passage will be December 21.

Посмотреть эту публикацию в Instagram The Fairy of Eagle Nebula Image Credit: NASA, ESA, The Hubble Heritage Team, (STScI/AURA) Explanation: The dust sculptures of the Eagle Nebula are evaporating. As powerful starlight whittles away these cool cosmic mountains, the statuesque pillars that remain might be imagined as mythical beasts. Featured here is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy. This fairy, however, is ten light years tall and spews radiation much hotter than common fire. The greater Eagle Nebula, M16, is actually a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open cluster of stars. This great pillar, which is about 7,000 light years away, will likely evaporate away in about 100,000 years. The featured image in scientifically re-assigned colors was released in 2005 as part of the fifteenth anniversary celebration of the launch of the Hubble Space Telescope.

Посмотреть эту публикацию в Instagram Gibbous Moon beyond Swedish Mountain Image Credit & Copyright: Göran Strand Explanation: This is a gibbous Moon. More Earthlings are familiar with a full moon, when the entire face of Luna is lit by the Sun, and a crescent moon, when only a sliver of the Moon’s face is lit. When more than half of the Moon is illuminated, though, but still short of full illumination, the phase is called gibbous. Rarely seen in television and movies, gibbous moons are quite common in the actual night sky. The featured image was taken in Jämtland, Sweden near the end of last month. That gibbous moon turned, in a few days, into a crescent moon, and then a new moon, then back to a crescent, and a few days ago back to gibbous. And this same gibbous moon is visible again tonight, leading up to the Full Beaver Moon that occurs Friday night. Setting up to capture a picturesque gibbous moonscape, the photographer was quite surprised to find an airplane, surely well in the foreground, appearing to fly past it.
