Пионер-10: первые 10.4 миллиарда км Pioneer 10: The First 6 Billion Miles
20.06.1998

Q: What was made by humans and is 6.5 billion miles away? A: Pioneer 10 - and last year was the 25th anniversary of its launch. More than 9.5 light-hours distant, Pioneer 10 is presently about twice as far from the Sun as Pluto, bound for interstellar space at 28,000 miles per hour.



Эйбел 370: гравитационная линза скопления галактик Abell 370: Galaxy Cluster Gravitational Lens
21.09.2009

What is that strange arc? While imaging the cluster of galaxies Abell 370, astronomers had noted an unusual arc to the right of many cluster galaxies. Although curious, one initial response was to avoid commenting on the arc because nothing like it had ever been noted before.



Полное лунное затмение над Таджикистаном A Total Lunar Eclipse Over Tajikistan
7.11.2022

If the full Moon suddenly faded, what would you see? The answer was recorded in a dramatic time lapse video taken during the total lunar eclipse in 2011 from Tajikistan. During a total lunar eclipse, the Earth moves between the Moon and the Sun, causing the moon to fade dramatically.



Газовая пуля из космического взрыва N49 Fast Gas Bullet from Cosmic Blast N49
30.06.2010

What is that strange blue blob on the far right? No one is sure, but it might be a speeding remnant of a powerful supernova that was unexpectedly lopsided. Scattered debris from supernova explosion N49 lights up the sky in this gorgeous composited image based on data from the Chandra and Hubble Space Telescopes.



Обращение вокруг чёрной дыры в фотонной сфере Circling a Black Hole at its Photon Sphere
2.07.2013

What would it look like to go right up to a black hole? One particularly interesting place near a black hole is its photon sphere, where photons can orbit in circles, a sphere 50 percent further out than the event horizon.



Остаток сверхновой Кеплера в рентгеновских лучах Kepler's Supernova Remnant in X Rays
15.05.2013

What caused this mess? Some type of star exploded to create the unusually shaped nebula known as Kepler's supernova remnant, but which type? Light from the stellar explosion that created this energized cosmic cloud was first seen on planet Earth in October 1604, a mere four hundred years ago.



Молодое звездное скопление NGC 346 Young Star Cluster NGC 346
2.05.2025

The most massive young star cluster in the Small Magellanic Cloud is NGC 346, embedded in our small satellite galaxy's largest star forming region some 210,000 light-years distant. Of course the massive stars of NGC 346 are short lived, but very energetic.



Тайна в гамма-свете A Mystery in Gamma Rays
24.03.2000

Gamma rays are the most energetic form of light, packing a million or more times the energy of visible light photons. What if you could see gamma rays? If you could, the familiar skyscape...



Самая плотная галактика The Densest Galaxy
4.10.2013

The bright core and outer reaches of giant elliptical galaxy M60 (NGC 4649) loom large at the upper left of this sharp close-up from the Hubble Space Telescope. Some 54 million light-years away and 120,000 light-years across, M60 is one of the largest galaxies in the nearby Virgo Cluster.



Темная река, текущая к Антаресу The Dark River to Antares
16.05.2020

A dark river seems to flow through this sky from the horizon toward colorful clouds near red giant star Antares. Murky looking, the dark river is a dusty nebula obscuring background starlight near the central Milky Way, although the dark dust nebula contains mostly hydrogen molecular gas.
