NGC 2403 в Жирафе NGC 2403 in Camelopardalis
2.06.2024

Magnificent island universe NGC 2403 stands within the boundaries of the long-necked constellation Camelopardalis. Some 10 million light-years distant and about 50,000 light-years across, the spiral galaxy also seems to have more than its fair share of giant star forming HII regions, marked by the telltale reddish glow of atomic hydrogen gas.


Вращающаяся Луна от "Лунного орбитального разведчика" APOD: 2024 June 2 Б Rotating Moon from LRO
1.06.2024

No one, presently, sees the Moon rotate like this. That's because the Earth's moon is tidally locked to the Earth, showing us only one side. Given modern digital technology, however, combined with many detailed images returned by the Lunar Reconnaissance Orbiter (LRO), a high resolution virtual Moon rotation movie has been composed.


Стерео-Елена Stereo Helene
31.05.2024

Get out your red/blue glasses and float next to Helene, small, icy moon of Saturn. Appropriately named, Helene is a Trojan moon, so called because it orbits at a Lagrange point. A Lagrange point is a gravitationally stable position near two massive bodies, in this case Saturn and larger moon Dione.


Кольцевая туманность вокруг WR 134 The Nebulous Realm of WR 134
30.05.2024

Made with narrowband filters, this cosmic snapshot covers a field of view over twice as wide as the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas.


Лунная корона над Парижем APOD: 2024 May 30 Б A Lunar Corona over Paris
29.05.2024

Why does a cloudy moon sometimes appear colorful? The effect, called a lunar corona, is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently.


Лестница на Млечный Путь APOD: 2024 May 29 Б Stairway to the Milky Way
28.05.2024

What happens if you ascend this stairway to the Milky Way? Before answering that, let's understand the beautiful sky you will see. Most eye-catching is the grand arch of the Milky Way Galaxy...


Возвращение знаменитой активной области и вспышка класса X на Солнце APOD: 2024 May 28 Б Solar X Flare as Famous Active Region Returns
27.05.2024

It's back. The famous active region on the Sun that created auroras visible around the Earth earlier this month has survived its rotation around the far side of the Sun -- and returned. Yesterday...


Молекулярное облако Хамелеон-I Chamaeleon I Molecular Cloud
26.05.2024

Dark markings and bright nebulae in this telescopic southern sky view are telltale signs of young stars and active star formation. They lie a mere 650 light-years away, at the boundary of the local bubble and the Chamaeleon molecular cloud complex.


Выброс солнечного волокна APOD: 2024 May 26 Б A Solar Filament Erupts
25.05.2024

What's happened to our Sun? Nothing very unusual -- it just threw a filament. Toward the middle of 2012, a long standing solar filament suddenly erupted into space, producing an energetic coronal mass ejection (CME).


Ударный кратер Маникуаган: вид из космоса Manicouagan Impact Crater from Space
24.05.2024

Orbiting 400 kilometers above Quebec, Canada, planet Earth, the International Space Station Expedition 59 crew captured this snapshot of the broad St. Lawrence River and curiously circular Lake Manicouagan on April 11. Right of center, the ring-shaped lake is a modern reservoir within the eroded remnant of an ancient 100 kilometer diameter impact crater.
