Карликовые галактики в скоплении Кома Dwarf Galaxies in the Coma Cluster

In visible light images, over a thousand galaxies are seen to lie within a volume about 20 million light-years across in the rich Coma Galaxy Cluster. But infrared images of the Coma Cluster have now been used to add thousands more to the Coma's galaxy count in the form of previously undiscovered dwarf galaxies.

Жидкое море на спутнике Сатурна Титане Liquid Sea on Saturns Titan

What is this vast dark region on Titan? Quite possible a sea of liquid hydrocarbons. The region was imaged earlier this month when the robotic Cassini spacecraft swooped past Saturn's cloudy moon and illuminated part of it with radar.

Яркая спиральная галактика M81: вид в телескоп Хаббла Bright Spiral Galaxy M81 from Hubble

The Hubble Space Telescope has resolved individual stars in a spectacular new image of nearby spiral galaxy M81. The feat is similar to Edwin Hubble's historic images with the Mt. Wilson 100-inch Hooker Telescope in the 1920s that resolved stars in neighboring galaxy M31.

Дыра на Марсе A Hole in Mars

Black spots have been discovered on Mars that are so dark that nothing inside can be seen. Quite possibly, the spots are entrances to deep underground caves capable of protecting Martian life, where it to exist. The unusual hole pictured above was found on the slopes of the giant Martian volcano Arsia Mons.

Туманность Конская голова The Horsehead Nebula

One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s.

Лунный Сатурн The Moon s Saturn

On May 22nd, just days after sharing the western evening sky with Venus, the Moon moved on to Saturn - actually passing in front of the ringed planet when viewed in skies over Europe, northern Africa, and western Asia.

Юпитер, Веста и Млечный Путь Jupiter, Vesta, and the Milky Way

In this gorgeous skyscape, gas giant Jupiter along with the stars and cosmic dust clouds of the Milky Way hang over the southern horizon in the early morning hours as seen from Stagecoach, Colorado, USA. Recorded on Thursday, Jupiter is the brightest object near picture center.

Тюльпан в Лебеде The Tulip in the Swan

This expansive (1-degree wide) telescopic view looks out along the plane of our Milky Way Galaxy toward the nebula rich constellation Cygnus the Swan. It is centered on a bright hydrogen emission region recorded in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101.

Венера рядом с Луной Venus Near the Moon

The two brightest objects in the night sky appeared to go right past each other last week. On the night of May 19, Earth's Moon and the planet Venus were visible in the same part of the sky, and at closest approach were less than one degree apart.

В центре отражательной туманности NGC 1333 In the Center of Reflection Nebula NGC 1333

The dust is so thick in the center of NGC 1333 that you can hardly see the stars forming. Conversely, the very dust clouds that hide the stars also reflects their optical light, giving NGC 1333's predominantly blue glow the general designation of a reflection nebula.
