UGC 12591: галактика с самым быстрым вращением UGC 12591: The Fastest Rotating Galaxy Known

Why does this galaxy spin so fast? To start, even identifying which type of galaxy UGC 12591 is difficult -- it has dark dust lanes like a spiral galaxy but a large diffuse bulge of stars like a lenticular.

Разноцветное северное сияние над Исландией Colorful Aurora over Iceland

You don't always see a scene this beautiful when you hike to an ancient volcano -- you have to be lucky. When the astrophotographer realized that aurora were visible two-weeks ago, he made a night-time run for the top of the caldera to see if he could capture them also reflected in the central lake.

Загадочные кольца сверхновой 1987A The Mysterious Rings of Supernova 1987A

What's causing those odd rings in supernova 1987A? Thirty years ago, in 1987, the brightest supernova in recent history was seen in the Large Magellanic Cloud. At the center of the featured picture is an object central to the remains of the violent stellar explosion.

Натюрморт с отражающей пылью Still Life with Reflecting Dust

In this beautiful celestial still life composed with a cosmic brush, dusty nebula NGC 2170 shines at the upper left. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a compact red emission region, and streamers of obscuring dust against a backdrop of stars.

От Сиван 2 до M31 Sivan 2 to M31

From within the boundaries of the constellation Cassiopeia (left) to Andromeda (right), this telescopic mosaic spans over 10 degrees in planet Earth's skies. The celestial scene is constructed of panels that are part of a high-resolution astronomical survey of the Milky Way in hydrogen-alpha light.

Кольцеобразное затмение после восхода Солнца Annular Eclipse After Sunrise

From northern Patagonia, morning skies were clear and blue on Sunday, February 26. This sweeping composite scene, overlooking Hermoso Valle, Facundo, Chubut, Argentina, follows the Sun after sunrise, capturing an annular solar eclipse. Created...

Солнечное затмение с огненным кольцом A Solar Eclipse with a Beaded Ring of Fire

What kind of eclipse is this? On Sunday, visible in parts of Earth's southern hemisphere, the Moon blocked part of the Sun during a partial solar eclipse. In some locations, though, the effect was a rare type of partial eclipse called an annular eclipse.

Белое овальное облако на Юпитере от Юноны A White Oval Cloud on Jupiter from Juno

This storm cloud on Jupiter is almost as large as the Earth. Known as a white oval, the swirling cloud is a high pressure system equivalent to an Earthly anticyclone. The cloud is one of a "string of pearls" ovals south of Jupiter's famous Great Red Spot.

Четыре изображения квазара вокруг галактики-линзы Four Quasar Images Surround a Galaxy Lens

An odd thing about the group of lights near the center is that four of them are the same distant quasar. This is because the foreground galaxy -- in the center of the quasar images and the featured image -- is acting like a choppy gravitational lens.

Грозовое облако суперячейка над Монтаной A Supercell Thunderstorm Cloud Over Montana

Is that a spaceship or a cloud? Although it may seem like an alien mothership, it's actually a impressive thunderstorm cloud called a supercell. Such colossal storm systems center on mesocyclones -- rotating updrafts that can span several kilometers and deliver torrential rain and high winds including tornadoes.
