PIX4619360: Nebula NGC 6334 in the Scorpion - The 'reddened' nebulosity of NGC 6334 - The nebula NGC 6334 is located about 5500 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. The star - forming nebula NGC 6334 shows no evidence of a blue component in their colour - indeed, the blue - light plate used in these 3 - colour pictures had no nebulous image at all - nor is there any obvious sign of the bright blue stars normally found in these objects. They are excellent examples of the phenomenon known as 'interstellar reddening', the selective removal of blue light by minute particles of dust in the line of sight. This accounts for both the ruddy hue and apparent absence of blue stars. The hot stars are present but only some of the red part of their light is seen so they are not conspicuous. This nebula is quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Careful measurement of the colour of stars associated with the nebula indicate that they are dimmed by a factor of about 10 in the green part of the spectrum, much more in the blue, but relatively little at red wavelengths. Some care has been taken to ensure that these images are as close to true - colour as possible / Bridgeman Images
PIX4620019: Eagle Nebula (IC 4703) and M16 star cluster in the Snake - The Eagle nebula in Serpens - The M16 star cluster is a cluster of young stars distant from 7000 years - light, formed about 2 million years ago in the Eagle nebula, IC 4703. These stars are much warmer than the Sun and can be 30 times more massive. Messier 16 is a cluster of young stars which formed about 2 million years ago from the gas and dust which still surrounds them. Brilliant blue stars of this type are much hotter than the Sun and can be up to thirty times more massive. The dark intrusions visible across the face of the nebula are condensations of dusty material which might one day collapse into yet more stars, should they survive the radiation from the bright stars, which is gradually etching them away. Bright red regions of photo - ionised hydrogen such as M16 are usually found in the spiral arms of galaxies and are often associated recent star formation. This example is about 7000 light years distant / Bridgeman Images
PIX4620021: Eagle Nebula (IC 4703) and M16 star cluster in the Snake - M16, The Eagle Nebula in Serpens - The M16 star cluster is a cluster of young stars from 7000 years - light, formed about 2 million years ago in the Eagle nebula, IC 4703. These stars are much warmer than the Sun and can be 30 times more massive. Image obtained by combining light through 3 different filters that highlight oxygen, hydrogen, and sulfur. Messier 16 is a cluster of young stars which formed about 2 million years ago from the gas and dust which still surrounds them. Brilliant blue stars of this type are much hotter than the Sun and can be up to thirty times more massive.

Image obtained with a telescope 61 cm in diameter. The two bright blue clouds are NGC 6589 and NGC 6590. Image taken with a 24 - inch telescope / Bridgeman Images

PIX4620159: Centre de la nebula Omega (M17) 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
