Christmas Tree Cluster and Cone Nebula, NGC 2264 Stretched Canvas Print
tagged with: stretch frame, stars, awesome astronomy pictures, xmastrclst, cone nebula, christmas tree cluster, star clusters, galaxies, starfields, nebulae, european southern observatory, eso, vista
Galaxies, Stars and Nebulae series A gorgeous outer space photograph featuring a colour image of the region known as NGC 2264 - an area of sky that includes the sparkling blue baubles of the Christmas Tree star cluster and the Cone Nebula.
It was created from data taken through four different filters (B, V, R and H-alpha) with the Wide Field Imager at ESO's La Silla Observatory, 2400 m high in the Atacama Desert of Chile in the foothills of the Andes.
The image shows a region of space about 30 light-years across.

Center of The Swan Nebula Stretched Canvas Prints

Galaxies, Stars and Nebulae series Amazingly this could almost be some underwater scene with strange creatures swimming in the aquamarine waters. It's actually the centre of the Swan Nebula, or M17, a hotbed of newly born stars wrapped in colourful blankets of glowing gas and cradled in an enormous cold, dark hydrogen cloud. This stunning picture was taken by the newly installed Advanced Camera for Surveys (ACS) aboard the NASA/ESA Hubble Space Telescope.
The region of the nebula shown in this picture is about 3500 times wider than our Solar System. The area also represents about 60 percent of the total view captured by ACS. The nebula resides 5500 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 - each about six times hotter and 30 times more massive than our 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 sulphur. Particularly striking is the rose-like feature, seen to the right of centre, which glows in the red light emitted by hydrogen and sulphur.
As the infant stars evaporate the surrounding cloud, they expose dense pockets of gas that may contain developing stars. Because these dense pockets are more resistant to the withering radiation than the surrounding cloud, they appear as sculptures in the walls of the cloud or as isolated islands in a sea of glowing gas. One isolated pocket is seen at the centre of the brightest region of the nebula and is about 10 times larger than our Solar System.

Stellar Nursery R136 in the Tarantula Nebula Stretched Canvas Print
tagged with: stars, galaxies, outer space, wallart, dorneblmc, stellar nursery, 30 doradus nebula, massive stars, tarantula nebula, astronomy, r136, large magellanic cloud, star cluster, amazing hubble images
Galaxies, Stars and Nebulae series Hundreds of brilliant blue stars wreathed by warm, glowing clouds in appear in this the most detailed view of the largest stellar nursery in our local galactic neighborhood. The massive, young stellar grouping, called R136, is only a few million years old and resides in the 30 Doradus (or Tarantula) Nebula, a turbulent star-birth region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way.
There is no known star-forming region in our galaxy as large or as prolific as 30 Doradus. Many of the diamond-like icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun. These hefty stars are destined to pop off, like a string of firecrackers, as supernovas in a few million years. The image, taken in ultraviolet, visible, and red light by Hubble's Wide Field Camera 3, spans about 100 light-years.
The movement of the LMC around the Milky Way may have triggered the massive cluster's formation in several ways. The gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have compressed gas in the LMC. Also, the pressure resulting from the LMC plowing through the Milky Way's halo may have compressed gas in the satellite. The cluster is a rare, nearby example of the many super star clusters that formed in the distant, early universe, when star birth and galaxy interactions were more frequent.
The LMC is located 170,000 light-years away and is a member of the Local Group of Galaxies, which also includes the Milky Way. The Hubble observations were taken Oct. 20-27, 2009. The blue color is light from the hottest, most massive stars; the green from the glow of oxygen; and the red from fluorescing hydrogen.
