Галактика M95 и сверхновая M95 with Supernova

Barred spiral galaxy M95 is about 75,000 light-years across, comparable in size to our own Milky Way and one of the larger galaxies of the Leo I galaxy group. In fact, it is part of a not quite so famous trio of Leo galaxies with neighbors M96 and M105, about 38 million light-years distant.

Полярное сияние над Исландией Aurora Over Iceland

If you see a sky like this -- photograph it. Three nights ago in Iceland, an adventurous photographer (pictured) chanced across a sky full of aurora and did just that. Afterwards, by stitching together five smaller photographs, the entire aurora-lit sky was recreated in this 180-degree panorama taken from VatnajЖkull glacier.

Эволюция Луны Evolution of the Moon

What is the history of the Moon? The Moon was likely created from debris expelled when a Mars-sized object violently impacted the Earth about 4.5 billion years ago. Just after gravitationally condensing, as imagined above, the glowing-hot surface of the Moon cooled and cracked.

Группа солнечных пятен AR 1429 Sunspot Group 1429 and the Distant Sun

What's that on the Sun? Over the past two weeks, one of the most energetic sunspot regions of recent years crossed the face of the Sun. Active Region 1429, visible above...

Юпитер и Венера с Земли Jupiter and Venus from Earth

It was visible around the world. The sunset conjunction of Jupiter and Venus was visible last week almost no matter where you lived on Earth. Anyone on the planet with a clear western horizon at sunset could see them. This week the two are still notable, even though Jupiter has sunk below the brighter Venus.

NGC 2683: спиральная галактика, видимая с ребра NGC 2683: Edge On Spiral Galaxy

This elegant island universe is cataloged as NGC 2683. It lies a mere 16 million light-years distant toward the northern constellation Lynx. A spiral galaxy comparable to our own Milky Way, NGC 2683 is seen nearly edge-on in the cosmic vista.

Яркие планеты и солнечный телескоп МакМас-Пирс Bright Planets at McMath Pierce Solar Telescope

Bright planets Venus and Jupiter are framed by the National Solar Observatory's McMath-Pierce Solar Telescope in this very astronomical scene. The photo was taken at Kitt Peak National Observatory on March 9.

Солнечная вспышка на гамма-небе Solar Flare in the Gamma ray Sky

What shines in the gamma-ray sky? The answer is usually the most exotic and energetic of astrophysical environments, like active galaxies powered by supermassive black holes, or incredibly dense pulsars, the spinning remnants of exploded stars.

Извержение на бурном Солнце Angry Sun Erupting

It's one of the baddest sunspot regions in years. Active Region 1429 may not only look, to some, like an angry bird -- it has thrown off some of the most powerful flares and coronal mass ejections of the current solar cycle.

Группа галактик M81 сквозь туманность на высокой галактической широте The M81 Galaxy Group Through the Integrated Flux Nebula

Large galaxies and faint nebulae highlight this deep image of the M81 Group of galaxies. First and foremost in the wide-angle 12-hour exposure is the grand design spiral galaxy M81, the largest galaxy visible in the image.
