PIX4621624: Cometary Globula CG30 in the Stern - Cometary Globule CG30 - Cometary cells are small clouds of isolated gases. These, called CG30/31/38, are located about 1300 light years ago in the constellation Pupus. The Cometary Globules CG 30/31/38 are located 1300 light years away in Vela/Puppis constellations; they appear as finger - like extensions extending out in different directions. Bright rimmed globules and their more evolved cousin the cometary globule represent fascinating dynamic structures formed by the interplay of cold molecular clouds and hot ionizing stars. Typically the head of the globule faces a hot O - type star. The blood cells are known to be the birthplace of low mass stars. The globule head of CG 30 contains the Herbig Haro object HH 120, which is the outflow signature of a pre - main sequence star / Bridgeman Images

PIX4623330: Planetary nebula M57 (NGC 6720) in Lyra - The Ring nebula M57 in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. Image obtained by the Hubble Space Telescope (HST). The Hubble Space Telescope has captured the sharpest view yet of M57, the Ring Nebula in Lyra, which is the most famous of all planetary nebulae. In this image, the telescope has looked down a tunnel of gas cast off by a dying star thousands of years ago. This photo reveals elongated dark clumps of material embedded in the gas at the edge of the nebula, and the dying central star floating in a blue haze of hot gas. The nebula is about a light - year in diameter, and is located some 2,000 light - years from Earth in the direction of the constellation Lyra / Bridgeman Images

PIX4624891: Saturn and satellites seen by the Hubble space telescope - Saturn rings edge - on with satellites - Saturn observed by the Hubble space telescope on February 24, 2009 when the Earth is in the same plane as the rings, seen by the slice. This phenomene occurs every 15 years. This sequence of images taken for just over three hours shows the movement from left to right of four satellites in front of the planet. From left to right on the top image we see the satellites Enceladus, Dione (the brightest ice satellite), Mimas and the largest satellite, Titan, orange. This sequence of images captures the parade of several of Saturn's moons transiting the face of the gas giant planet from left to right during more than three hours. This is a rare event because the rings are tilted edge on to Earth every 15 years. The top frame captures the giant moon Titan and its shadow near Saturn's northern polar hood. Tiny Mimas and its shadow have just entered the left limb of Saturn, slightly above the rings. To the far left off the disk, Dione, the brightest of the icy moons in this view - and Enceladus, fainter and farther to the left - can easily be seen just above the rings. This picture sequence was taken with Hubble's Wide Field Planetary Camera 2 on February 24, 2009, when Saturn was at a distance of roughly 775 million miles (1.25 billion kilometers) from Earth. Hubble can see details as small as 190 miles (300 km) across on Saturn / Bridgeman Images

PIX4620728: Nebula NGC 7635 in Cassiopee - The Bubble Nebula: This nebula is located about 8000 light years from Earth. A star 40 times more massive than our Sun, called Wolf-Rayet, is responsible for the formation of this bubble; it is the star BD+60* 2522. Image obtained by the space telescope Hubble - The Bubble Nebula, also known as NGC 7635, is an emission nebula located 8 000 light-years away - This complete view of the Bubble Nebula allows us to fully appreciate the almost perfectly symmetrical shell which gives the nebula its name. This shell is the result of a powerful flow of gas - known as a stellar wind - from the bright star visible just to the left of centre in this image. The star, SAO 20575, is between ten and twenty times the mass of the Sun and the pressure created by its stellar wind forces the surrounding interstellar material outwards into this bubble-like form - The giant molecular cloud that surrounds the star - glowing in the star's intense ultraviolet radiation - tries to stop the expansion of the bubble. However, although the sphere already measures around ten light-years in diameter, it is still growing, owing to the constant pressure of the stellar wind - currently at more than 100,000 kilometers per hour! - This stunning new image was observed by the NASA/ESA Hubble Space Telescope / Bridgeman Images

PIX4622327: Elephant tube nebula (VDB 142) in Cephee - The Elephant Trunk Nebula (VDB 142) in Cepheus - IC1396, VDB 142. Nebula located about 2700 years - light from Earth. The Elephant Trunk Nebula (IC 1396A) in Cepheus is part of the larger IC 1396 complex which spans a large area of the sky measuring 170 by 140 arc - minutes and is one of the brightest emission nebulae with a magnitude of 3.5. The western portion of IC 1396 contains the Elephant Trunk Nebula (IC 1396A) which is characterized with H - II emissions, dark lanes and globules as well as a small reflection nebula. The IC 1396 complex is technically a star cluster (aka Cr 439, Trumpler 37) owing to the presence of a developing open but loose cluster at the heart of this rich nebulosity. This open star cluster is comprised of 50 - 100 member stars which vary in brightness spanning an area of approximately 50 'in diameter and which are not very well detached from the background sky. This stellar nursery lies at a distance of 2,720 light - years away / Bridgeman Images

PIX4620193: Center of the Omega Nebula (M17) in the sagittarius seen by HST - Center of the Omega Nebula, a hotbed of newly born stars wrapped in colorful blankets of glowing gas and cradled in an enormous cold, dark hydrogen cloud. This picture was taken by the Advanced Camera for Surveys (ACS) aboard Nasa's Hubble Space Telescope. The region of the nebula shown in this photograph is about 3,500 times wider than our solar system. The area represents about 60 percent of the total view captured by ACS. The nebula, also called M17 and the Swan Nebula, resides 5,500 light - years away in the constellation Sagittarius. Like its famous cousin in Orion, the Swan Nebula is illuminated by ultraviolet radiation from young, massive stars, located just beyond the upper right corner of the image. Each star is about six times hotter and 30 times more massive than the Sun. The powerful radiation from these stars evaporates and erodes the dense cloud of cold gas within which the stars formed. The blistered walls of the hollow cloud shine primarily in the blue, green, and red light emitted by excited atoms of hydrogen, nitrogen, oxygen, and sulfur. Particularly striking is the rose - like feature, seen to the right of center, which glows in the red light emitted by hydrogen and sulfur. ACS made this observation on April 1 and 2, 2002. The color image is constructed from four separate images taken in these filters: blue, near infrared, hydrogen alpha, and doubly ionized oxygen / Bridgeman Images

PIX4620599: Nebula NGC 7129 in Cephee: Nebula by reflexion located 3300 light years from Earth. This nebula houses very young stars, aged less than a million years old. - NGC 7129 is a young compact star forming region which displays an unusual patchwork of colorful nebulosity and bright stars contrasted against the dust clouds of the Milky Way. NGC 7129 contains several bright reflection nebulae including the large blue reflection cloud NGC 7133 and the unusual small yellow reflection cloud LBN497. Also conspicuous in the field are several bright Herbig-Haro objects, the signatures of young stellar objects soon to emerge in the main sequence. The dominant blue reflection nebula, NGC 7133 is illuminated by two young B-type stars BD+65* 1637 and BD+65* 1638. Both stars are less than one million years old and represent the core of NGC 7129, a small cluster of low mass stars which populate the 36 light year wide cavity / Bridgeman Images

PIX4620650: Nebula NGC 7635 in Cassiopee - North is at top. Seemingly adrift in a cosmic sea of stars and glowing gas, the delicate, floating apparition near the center (next to a blue tinted star) of this widefield view is cataloged as NGC 7635 - The Bubble Nebula. A mere 10 light - years wide, the tiny Bubble Nebula and the larger complex of interstellar gas and dust clouds are found about 11,000 light - years distant, straddling the boundary between the parental constellations Cepheus and Cassiopeia. Also included in the vista is open star cluster M52 (upper left), some 5,000 light - years away. The image spans about 2.7 degrees on the sky corresponding to a width of just over 500 light - years at the estimated distance of the Bubble Nebula. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory / Bridgeman Images

PIX4620709: Nebula NGC 7635 in Cassiopee - The Bubble Nebula (NGC 7635) in Cassiopeia - This nebula is located about 7100 years - light from Earth. A star 40 times more massive than our Sun, called Wolf - Rayet, is responsible for the formation of this bubble; it is the star BD+60* 2522. The Bubble Nebula in Cassiopeia is one of the most dramatic emission nebulae visible in the northern hemisphere. Lying at a distance of about 7,000 light - years away and spanning six light - years in diameter, NGC 7635 is quite bright with a magnitude of 7.0. The star in the middle of the bubble, BD+602522, is responsible for this stunning site, for this very hot star emits so much UV radiation that it is able to also heat and excite the surrounding dust and gas, thus emitting its own radiation. It is a Wolf - Rayet star, a very luminous star and also very short - lived. This Wolf - Rayet star is 40 times as massive than our sun / Bridgeman Images
