Туманность Ориона в линиях кислорода, водорода и серы Orion Nebula in Oxygen, Hydrogen, and Sulfur

The Great Nebula in Orion, an immense, nearby starbirth region, is arguably the most famous of all astronomical nebulae. The Orion Nebula, also known as M42, is shown above through ultraviolet and blue filters augmented with three exact colors specifically emitted by hydrogen, oxygen, and sulfur.

Кассини получил изображения кольца A Сатурна Cassini Images Saturns A Ring

What are Saturn's rings made of? In an effort to find out, the robot spacecraft Cassini that entered orbit around Saturn two weeks ago took several detailed images of the area surrounding Saturn's large A ring in ultraviolet light.

Анизотропия микроволнового фона во Вселенной WMAP Resolves the Universe

Analyses of a new high-resolution map of microwave light emitted only 380,000 years after the Big Bang appear to define our universe more precisely than ever before. The eagerly awaited results announced last year from the orbiting Wilkinson Microwave Anisotropy Probe resolve several long-standing disagreements in cosmology rooted in less precise data.

Стереоизображение кратеров Фебы Phoebe Craters in Stereo

Get out your red/blue glasses and gaze across the spectacular, cratered terrain of Saturn's icy moon Phoebe in stereo. The dramatic 3-D perspective spans roughly 50 kilometers and is based...

Окольцованные туманности Ringed Nebulae

Have you heard a lot about ringed planets lately? Well, consider this gorgeous celestial vista centered on the Milky Way's own planetary nebula M57, the famous Ring Nebula. The wide view...

Цвета звезд Южного Креста Southern Cross Star Colors

Fix your camera to a tripod, lock the shutter open, and you can easily record an image of star trails, the graceful concentric arcs traced by the stars as planet Earth rotates on its axis.

N11B: звездное облако в БМО N11B: Star Cloud of the LMC

Massive stars, abrasive winds, mountains of dust, and energetic light sculpt one of the largest and most picturesque regions of star formation in the Local Group of Galaxies. Known as N11, the region...

Инфракрасные изображения Титана с борта Кассини Titan from Cassini in Infrared

Could life exist under the smog of Titan? If not, what is creating all of the methane? To help answer these questions, the largest and most mysterious moon of Saturn got a quick first look from the Cassini robot spacecraft soon after entering orbit around the giant planet last week.

Волны плотности в кольцах Сатурна на изображениях Кассини Cassini Images Density Waves in Saturns Rings

What causes the patterns in Saturn's rings? The Cassini spacecraft just entering orbit around Saturn has started sending back spectacular images of Saturn's immense ring system in unprecedented detail. The physical cause for many of newly resolved ring structures is not always understood.

Кольцевая туманность M57 M57: The Ring Nebula

Except for the rings of Saturn, the Ring Nebula (M57) is probably the most famous celestial band. This planetary nebula's simple, graceful appearance is thought to be due to perspective -- our view from planet Earth looking straight into what is actually a barrel-shaped cloud of gas shrugged off by a dying central star.
