Wild Duck Cluster (Messier 11) ~ Open cluster or galactic cluster, located around 6000 light-years away in the constellation of Scutum (The Shield). The Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile has taken this beautiful image, dappled with blue stars, of one of the most star-rich open clusters currently known, being almost 20 light-years across and home to close to 3000 stars.

Baby stars are forming near the eastern rim of the cosmic cloud Perseus in this infrared image from NASA's Spitzer Space Telescope. The baby stars are approximately three million years old and are shown as reddish-pink dots to the right of the image.
Molecular cloud Cepheus B, located in our Galaxy at about 2,400 light years from the Earth. A molecular cloud is a region containing cool interstellar gas and dust left over from the formation of the galaxy and mostly contains molecular hydrogen. - Credit: NASA/JPL-Caltech/ et al
M51, whose name comes from being the 51st entry in Charles Messier's catalog, is considered to be one of the classic examples of a spiral galaxy. At a distance of about 30 million light years from Earth, it is also one of the brightest spirals in the night sky. A composite image of M51, also known as the Whirlpool Galaxy, shows the majesty of its structure in a dramatic new way through several of NASA's orbiting observatories.
