Astronomy Picture Of the Day (APOD)

Кольца и времена года Сатурна Rings and Seasons of Saturn

On Saturn, the rings tell you the season. On Earth, today marks a solstice, the time when the Earth's spin axis tilts directly toward the Sun. On Earth's northern hemisphere, today is the Summer Solstice, the day of maximum daylight.

Лайтсейл-А LightSail A

Hitching a ride to low Earth orbit, LightSail A accomplished a challenging test mission, unfurling its 32 square meter mylar solar sail on June 7. This dramatic image from one of the bread loaf sized spacecraft's fisheye cameras captures the deployed sail glinting in sunlight.

M64: галактика Подбитый Глаз M64: The Black Eye Galaxy

This big, bright, beautiful spiral galaxy is Messier 64, often called the Black Eye Galaxy or the Sleeping Beauty Galaxy for its heavy-lidded appearance in telescopic views. M64 is about 17 million light-years distant in the otherwise well-groomed northern constellation Coma Berenices.

M45: звездное скопление Плеяды M45: The Pleiades Star Cluster

Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as dusty as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen without binoculars from even the depths of a light-polluted city.

Цветная лунная корона A Colorful Lunar Corona

The effect is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud.

M101: галактика Вертушка M101: The Pinwheel Galaxy

Why do many galaxies appear as spirals? A striking example is M101, shown above, whose relatively close distance of about 27 million light years allows it to be studied in some detail. Observational evidence...

1000 солов 1000 Sols

Shortly before Mars' June 2015 conjunction, the Curiosity Rover celebrated 1000 sols on the red planet. After its August 5, 2012 landing, Curiosity's 1000th sol or martian day on the surface corresponded to planet Earth's calendar date May 31, 2015.

Braided, serpentine filaments of glowing gas suggest this nebula's popular name, The Medusa Nebula.

Like its mythological namesake, the nebula is associated with a dramatic transformation.
