Галактики в Пегасе Galaxies in Pegasus
23.10.2014

This wide, sharp telescopic view reveals galaxies scattered beyond the stars and faint dust nebulae of the Milky Way at the northern boundary of the high-flying constellation Pegasus. Prominent at the upper right is NGC 7331.


Сверкающая группа солнечных пятен AR 2192 Sunspot Group AR 2192 Crackles
22.10.2014

One of the largest sunspot groups in recent years is now crossing the Sun. Labelled Active Region 2192, it has already thrown a powerful solar flare and has the potential to produce more.


Мимас: маленький спутник с большим кратером Mimas: Small Moon with a Big Crater
21.10.2014

Whatever hit Mimas nearly destroyed it. What remains is one of the largest impact craters on one of Saturn's smallest moons. The crater, named Herschel after the 1789 discoverer of Mimas, Sir William Herschel, spans about 130 kilometers and is pictured above.


Комета Сайдинг-Спринг пролетает мимо Марса Comet Siding Spring Passes Mars
20.10.2014

Yesterday, a comet passed very close to Mars. In fact, Comet C/2013 A1 (Siding Spring) passed closer to the red planet than any comet has ever passed to Earth in recorded history. To take...


Комета МакНота над Новой Зеландией Comet McNaught Over New Zealand
19.10.2014

Comet McNaught was perhaps the most photogenic comet of modern times -- from Earth. After making quite a show in the northern hemisphere in early January of 2007, the comet moved south and developed a long and unusual dust tail that dazzled southern hemisphere observers.


Скопление Мелотт 15 в туманности Сердце Melotte 15 in the Heart
18.10.2014

Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15.


Мессье 6 и комета Сайдинг-Спринг Messier 6 and Comet Siding Spring
17.10.2014

This looks like a near miss but the greenish coma and tail of Comet Siding Spring (C/2013 A1) are really 2,000 light-years or so away from the stars of open cluster Messier 6. They do appear close together though, along the same line-of-sight in this gorgeous October 9th skyscape toward the constellation Scorpius.


Автопортрет Розетты Rosetta s Selfie
16.10.2014

This Rosetta spacecraft selfie was snapped on October 7th. At the time the spacecraft was about 472 million kilometers from planet Earth, but only 16 kilometers from the surface of comet 67P/Churyumov-Gerasimenko. Looming beyond...


Загадочный изменяющийся объект на Титане Mysterious Changing feature on Titan
15.10.2014

What is that changing object in a cold hydrocarbon sea of Titan? Radar images from the robotic Cassini spacecraft orbiting Saturn have been recording the surface of the cloud-engulfed moon Titan for years. When...


Корона полярного сияния над Норвегией Auroral Corona over Norway
14.10.2014

Higher than the highest mountain lies the realm of the aurora. Auroras rarely reach below 60 kilometers, and can range up to 1000 kilometers. Aurora light results from energetic electrons and protons striking atoms and molecules in the Earth's atmosphere.
