Млечный Путь над станцией Боску Алегре в Аргентине Milky Way over Bosque Alegre Station in Argentina

What are those streaks of light in the sky? First and foremost, the arching structure is the central band of our Milky Way galaxy. Visible in this galactic band are millions of distant stars mixed with numerous lanes of dark dust.

Спиральная галактика M96 от Хаббла Spiral Galaxy M96 from Hubble

Dust lanes seem to swirl around the core of Messier 96 in this colorful, detailed portrait of the center of a beautiful island universe. Of course M96 is a spiral galaxy, and counting...

На спутнике Сатурна Энцеладе возможно существование глобального океана Global Ocean Suspected on Saturns Enceladus

Do some surface features on Enceladus roll like a conveyor belt? A leading interpretation of images taken of Saturn's most explosive moon indicate that they do. This form of asymmetric tectonic activity, very...

Протуберанец на Солнце A Prominence on the Sun

This eerie landscape of incandescent plasma suspended in looping and twisted magnetic fields stretched toward the Sun's eastern horizon on September 16. Captured through a backyard telescope and narrowband filter in light from ionized hydrogen, the scene reveals a gigantic prominence lofted above the solar limb.

Ландшафт на Плутоне A Plutonian Landscape

This shadowy landscape of majestic mountains and icy plains stretches toward the horizon of a small, distant world. It was captured from a range of about 18,000 kilometers when New Horizons looked back toward Pluto, 15 minutes after the spacecraft's closest approach on July 14.

Треугольник Пикеринга в Вуали Pickering s Triangle in the Veil

Chaotic in appearance, these filaments of shocked, glowing gas break across planet Earth's sky toward the constellation of Cygnus, as part of the Veil Nebula. The Veil Nebula itself is a large supernova remnant, an expanding cloud born of the death explosion of a massive star.

Яркие пятна в кратере Оккатор на Церере разрешены Bright Spots Resolved in Occator Crater on Ceres

What created these bright spots on Ceres? The spots were first noted as the robotic Dawn spacecraft approached Ceres, the largest object in the asteroid belt, in February, with the expectation that the mystery would soon be solved in higher resolution images. However, even after Dawn arrived at Ceres in March, the riddle remained.

Спиральное полярное сияние над Исландией A Spiral Aurora over Iceland

What's happened to the sky? Aurora! Captured late last month, this aurora was noted by Icelanders for its great brightness and quick development. The aurora resulted from a solar storm, with high energy particles bursting out from the Sun and through a crack in Earth's protective magnetosphere a few days later.

Вид на Плутон над областью Ктулху Pluto from above Cthulhu Regio

New high resolution images of Pluto are starting to arrive from the outer Solar System. The robotic New Horizons spacecraft, which zoomed by Pluto in July, has finished sending back some needed engineering data and is now transmitting selections from its tremendous storehouse of images of Pluto and its moons.

Частное солнечное затмение над Техасом A Partial Solar Eclipse over Texas

It was a typical Texas sunset except that most of the Sun was missing. The location of the missing piece of the Sun was not a mystery -- it was behind the Moon. Featured here...
