The Ring Nebula in Lyra lies 2.300 light years from Earth. It is estimated to have been expanding for about 1600 years.
The whirlpool galaxy, also called Messier 51 (M51), is located in the constellation of Canes Venatici. Charles Messier discovered the brighter galaxy NGC 5194 in 1773 and his friend Pierre Mechain found the secondary nebula, NGC 5195, in 1781.
The Pinwheel Galaxy (also known as Messier 101 or NGC 5457) is estimated to contain at least one trillion stars—about 100 billion of them could be similar to our sun.

This heavenly view of the Milky Way was taken in the South Pacific paradise of Mangaia, the most southerly of the Cook Islands. This image was chosen as one of the winners of the National Maritime Museum's Astrophotographer of the Year 2011 Contest.
Jupiter is the most massive planet in our solar system; with four large moons and many smaller moons it forms a kind of miniature solar system. The massive planet will be in opposition to the sun this weekend.
Skywatcher Tunc Tezel took this image of the night sky atop La Palma in the Canary Islands on a night with no moon and at a time when the milky way would not create much skyglow. Multiple exposures are taken to create enough light.
Skywatcher Amir H. Abolfath captured this photo of the setting sun over the Zagros Mountains of Iran. The green flash above the sun lasts for mere seconds making it often difficult to observe.
Skywatcher Per-Magnus Heden wondered if the Vikings gazed at the same starry sky, which includes the constellation Orion at bottom, when he took this photo in Feb. 2011.
Skywatcher Kwon, O Chul of The World At Night (TWAN), shot this image of the Northern Lights at Yellowknife in northern Canada.
Skywatcher Aleksandr Yuferev captured the first partial solar eclipse of the year through smoke from a chimney in Russia. The eclipse was visible from Europe to North Africa, Middle East and central Asia.
The photographer was in a dark Alpine forest near Tyrol, about 19 miles (30 kilometers) south of Innsbruck. Multiple exposures are made to collect enough light for an image that would otherwise not be evident to the eye.
Lunar and solar halos are caused when light passes through ice crystals formed in clouds through the sky.
Skywatcher Yuichi Takasaki took this photo of deep violet hues in an auroral display. Multiple exposures are made to collect enough light for an image that would otherwise not be evident to the eye.
The region lies near the southern end of Taurus located on the border of the constellations of Taurus and Perseus more than 400 light-years away. A light-year is the distance light travels in one year, or about 6 trillion miles (10 trillion kilometers).
Hungarian Skywatcher Tamas Ladanyi of The World At Night (TWAN) took this stunning photo of the smallest full moon of 2011, which occurred Oct. 11.
Multiple exposures are made to collect enough light for an image that would otherwise not be evident to the eye.
More than 30 images were taken to make this composite photo of the sun's movement across the sky in 2011. The images shows what scientists call the analemma, the movement of the sun in the sky over the course of a year. The background image was also taken separately without a solar filter.
Multiple exposures are made to collect enough light for an image that would otherwise not be evident to the eye.
