Зеленый луч: видео Video of a Green Flash
10.11.2021

Many think it is just a myth. Others think it is true but its cause isn't known. Adventurers pride themselves on having seen it. It's a green flash from the Sun. The truth is the green flash does exist and its cause is well understood.


Все эти космические картинки поддельные, кроме одной All of These Space Images are Fake Except One
9.11.2021

Why would you want to fake a universe? For one reason -- to better understand our real universe. Many astronomical projects seeking to learn properties of our universe now start with a robotic telescope taking sequential images of the night sky.


Волокно отрывается от Солнца A Filament Leaps from the Sun
8.11.2021

Why, sometimes, does part of the Sun's atmosphere leap into space? The reason lies in changing magnetic fields that thread through the Sun's surface. Regions of strong surface magnetism, known as active regions, are usually marked by dark sunspots.


Туманность Кошачий Глаз в оптике и рентгеновских лучах The Cats Eye Nebula in Optical and X-ray
7.11.2021

To some it looks like a cat's eye. To others, perhaps like a giant cosmic conch shell. It is actually one of brightest and most highly detailed planetary nebula known, composed of gas expelled in the brief yet glorious phase near the end of life of a Sun-like star.


Галактика между двух друзей The Galaxy Between Two Friends
6.11.2021

On an August night two friends enjoyed this view after a day's hike on the Plateau d'Emparis in the French Alps. At 2400 meters altitude the sky was clear. Light from a setting moon illuminates the foreground captured in the simple vertical panorama of images.


Темный Морской конек в Цефее The Dark Seahorse in Cepheus
5.11.2021

Light-years across, this suggestive shape known as the Seahorse Nebula appears in silhouette against a rich, luminous background of stars. Seen toward the royal northern constellation of Cepheus, the dusty, obscuring clouds are part of a Milky Way molecular cloud some 1,200 light-years distant.


NGC 147 и NGC 185 NGC 147 and NGC 185
4.11.2021

Dwarf galaxies NGC 147 (left) and NGC 185 stand side by side in this sharp telescopic portrait. The two are not-often-imaged satellites of M31, the great spiral Andromeda Galaxy, some 2.5 million light-years away.


Туманности Конская Голова и Пламя The Horsehead and Flame Nebulas
3.11.2021

The Horsehead Nebula is one of the most famous nebulae on the sky. It is visible as the dark indentation to the orange emission nebula at the far right of the featured picture. The horse-head feature is dark because it is really an opaque dust cloud that lies in front of the bright emission nebula.


SN Реквием: сверхновая, которую увидели три раза SN Requiem: A Supernova Seen Three Times So Far
2.11.2021

We've seen this same supernova three times -- when will we see it a fourth? When a distant star explodes in a supernova, we're lucky if we see it even once.


Водопад и Млечный Путь A Waterfall and the Milky Way
1.11.2021

The dream was to capture both the waterfall and the Milky Way together. Difficulties included finding a good camera location, artificially illuminating the waterfall and the surrounding valley effectively, capturing the entire scene with...
