Циклоны на северном полюсе Юпитера Cyclones at Jupiter s North Pole

Juno's Jovian Infrared Auroral Mapper data was used to construct this stunning view of cyclones at Jupiter's North Pole. Measuring the thermal emission from Jovian cloud tops, the infrared the observations are not restricted to the hemisphere illuminated by sunlight.

Дуги, джеты и ударные волны около NGC 1999 Arcs, Jets, and Shocks near NGC 1999

This tantalizing array of nebulas and stars can be found about two degrees south of the famous star-forming Orion Nebula. The region abounds with energetic young stars producing jets and outflows that push through the surrounding material at speeds of hundreds of kilometers per second.

Разноцветное свечение атмосферы вокруг Млечного Пути Colorful Airglow Bands Surround Milky Way

На юго-западе моря Изобилия Southwest Mare Fecunditatis

Frank Borman, James Lovell, and William Anders journeyed from Earth to the Moon and back again in December of 1968. From lunar orbit, their view of craters in southwest Mare Fecunditatis is featured in this stereo anaglyph, best experienced from armchairs on planet Earth with red/blue glasses.

Следы звезд над горами Альборц Alborz Mountain Star Trails

Colourful star trails arc through the night in this wide-angle mountain and skyscape. From a rotating planet, the digitally added consecutive exposures were made with a camera fixed to a tripod and looking south, over northern Iran's Alborz Mountain range.

Лунный Икс The Lunar X

The striking X in this lunarscape is easily visible in binoculars or a small telescope, but not too many have seen it. The catch is, this lunar X is fleeting and only apparent in the hours before the Moon's first quarter phase.
