Nebulae NGC 6334 and NGC 6357 in Scorpio - Nebulae NGC 6334 and NGC 6357 in Scorpius - These nebulae are located approximately 5500 years - light from Earth. Image made with the 1.2m Telescope of Schmidt UK from Siding Spring. The star - forming nebulae NGC 6334 and NGC 6357 show 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. These nebulae are quite nearby (5500 light years) but located close to the Galactic plane and are buried in the dust of the Milky Way. Ca

Saturn in false colours - Saturn in infrared - The planet Saturn seen in visible and infrared by the Cassini probe on November 1, 2008. This false - color composite image, constructed from data obtained by Nasa's Cassini spacecraft, shows Saturn's rings and southern hemisphere. The composite image was made from 65 individual observations by Cassini's visual and infrared mapping spectrometer in the near - infrared portion of the light spectrum on Nov. 1, 2008. The observations were each six minutes long. In this image constructed from data collected in the near - infrared wavelengths of light, scientists designated blue to indicate sunlight reflected at a wavelength of 2 microns, green to indicate sunlight reflected at 3 microns and red to indicate thermal emission at 5 microns. Saturn's rings reflect sunlight at 2 microns, but not at 3 and 5 microns, so they appear deep blue. Saturn's high altitude haze reflects sunlight at both 2 and 3 microns, but not at 5 microns, and so it appears

Plum varieties, Prunus domestica var. claudiana: Green Gage, White Gage and Blue Gage. Handcoloured stipple engraving of an illustration by George Brookshaw from his own “” Pomona Britannica,”” London, Longman, Hurst, etc., 1817. The quarto edition of the original folio edition published from 1804-1812. Brookshaw (1751-1823) was a successful cabinet maker who disappeared in the 1790s before returning as a flower painter with the anonymous “” New Treatise on Flower Painting,””” 1797.

Detail of the horse's head nebula by the VLT - Horsehead Nebula, which is situated in the Orion molecular cloud complex. Its official name is Barnard 33 and it is a dust protrusion in the southern region of the dense dust cloud Lynds 1630, on the edge of the HII region IC 434. The distance to the region is about 1400 light - years (430 pc). This beautiful colour image was produced from three images obtained with the multi - mode FORS2 instrument at the second VLT Unit Telescope (KUEYEN) on February 1, 2000. Three predominant colours are seen in the image: red from the hydrogen (H - alpha) emission from the HII region; brown for the foreground obscuring dust; and blue - green for scattered starlight. The blue - green regions of the Horsehead Nebula correspond to regions not shadowed from the light from the stars in the H II region to the top of the picture and scatter stellar radiation towards the observer; these are thus 'mountains' of dust

Comete Hyakutake - Comet Hyakutake - Comete Hyakutake March 1996. This is the spectacular Comet Hyakutake as it passed closest to Earth in March of 1996. The solid portion or nucleus of a comet is made up of ice, frozen gases, dust and small rock. And it is relatively small - less than 15 miles in diameter. As its orbit takes it closer to the sun, this frozen mass begins to melt and a coma, which is a gaseous cloud, develops around the nucleus. This coma can grow to be tens of thousands of miles in diameter. Finally a tail also develops which can become millions of miles long. This color photo reveals the blue - green glow around the coma, the yellow - red shroud of a dust tail, and the many long blue streamers of the ion tail

In this image, the bright central star is in the middle of the green ring of gas. Its companion star is diagonally above it at 10 o'clock. A spur of gas (green) is forming a faint bridge to the companion star due to gravitational attraction. The image also shows a ring of gas (green) surrounding the central star, with bubbles of gas to the lower left and upper right of the ring. The wind of material propelled by radiation from the hot central star has created enough pressure to blow open holes in the ends of the bubbles, allowing gas to escape. The red curved lines represent bright gas that is heated by a “” shock””” caused when the central star's wind hits the walls of the bubbles.

Planetary nebula NGC 6369 in Ophiuchus/HST - NGC 6369 is known to amateur astronomers as the “” Little Ghost Nebula,”” because it appears as a small, ghostly cloud surrounding the faint, dying central star. NGC 6369 lies in the direction of the constellation Ophiuchus, at a distance estimated to be between about 2,000 and 5,000 light - years from Earth. When a star with a mass similar to that of our own Sun nears the end of its lifetime, it expands in size to become a red giant. The red - giant stage ends when the star expels its outer layers into space, producing a faintly glowing nebula. Astronomers call such an object a planetary nebula, because its round shape resembles that of a planet when viewed with a small telescope.

Sandy Cay - Bahamas - Seabed currents and sandbanks on Sandy Cay and Long Island, Bahamas. Image obtained on 27 November 2010 from the International Space Station (ISS). This astronaut photograph, taken from the International space station on November 27, 2010, provides a view of tidal flats and channels near Sandy Cay, on the western side of Long Island and along the eastern margin of the Great Bahama Bank (North is top). The continuously exposed parts of the island are brown, a result of soil formation and vegetation growth. To the north of Sandy Cay, an off - white tidal flat composed of carbonate sediments is visible; light blue - green regions indicate shallow water on the tidal flat. The tidal flow of seawater is concentrated through gaps in the land surface, leading to the formation of relatively deep channels that cut into the sediments.

Infrared view of the Andromeda galaxy - Composite of three different wavelengths 24 microns (blue), 70 microns (green), and 160 microns (red). Using these three bands, we can know the temperature differences of the dust: the warmest are the brightest at 24 microns and the coldest shine at 160 microns. The blue/white areas contain the hottest dust. View obtained by Spitzer space telescope on 25 August 2004. The multi - wavelength view of Andromeda combines images taken at 24 microns (blue), 70 microns (green), and 160 microns (red). Using all three bands from the multiband imaging photometer allows astronomers to measure the temperature of the dust by its color. The warmest dust is brightest at 24 microns while the coolest is most evident at 160 microns. The blue/white areas have the hottest dust, as seen in the bulge and in the star - forming areas along the arms. The cooler dust floating further out in the ring and arms are in the redder regions. The data were taken on August 25, 2004

Centaurus A elliptical galaxy (NGC 5128) in Centaurus - Galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million light years away from Earth in the southern constellation of Centaurus. A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This Giant Galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. Centaurus A is a most unusual galaxy. The circular, uniformly bright portion is composed of several thousand million stars, most of them old and yellowish. The galaxy is girded by a dense dust lane which obscures and reddens the light of stars behind it. Some

The bright white region of this image shows the icy cap that covers Mars' south pole, composed of frozen water and carbon dioxide. The southern cap reaches some 3 km thick in places, and is around 350 km in diameter. This icy region is permanent; in the martian winter another, thinner ice cap forms over the top of it, stretching further out across the planet and disappearing again when the weather warms up. Mars Express imaged this area of March on 17 December 2012, in infrared, green and blue light, using its High Resolution Stereo Camera.

Andromede Galaxy (M31) infrared view - The Andromeda galaxy seen in infrared - This image shows the difference in infrared radiation between the light emitted by the aged stars (blue) and that emitted by the dust (star-forming zone, yellow and red). This image obtained by the WISE satellite also distinguishes the two Andromede satellite galaxies, M32 (above the nucleus of the Andromede galaxy) and NGC 205 (M110) below. Infrared composite at the following wavelengths: 3.4 and 4.6 microns (blue), 12 microns (green), and 22 microns dust sensitive, red. M31, is captured in full in this new image from Nasa's Wide - field Infrared Survey Explorer, or WISE. The mosaic covers an area equivalent to more than 100 full moons, or five degrees across the sky.

Saturn en jour vue par Cassini - Backlit Saturn seen by Cassini - Mosaic of 141 photos obtained by the Cassini probe on 19 July 2013 at a distance of 1.2 million km from the planet. The Cassini probe was then in the shadow of the Planet Saturn; this portrait of the Giant Planet highlights its ring system and seven of its satellites appear in the image. The planets Mars, Venus and Earth are also visible. On July 19, 2013, Nasa's Cassini spacecraft slipped into Saturn's shadow and turned to image the planet, seven of its moons, its inner rings - and, in the background, our home planet, Earth. With both Cassini's wide-angle and narrow-angle cameras aimed at Saturn, Cassini was able to capture 323 images in just over four hours. This final mosaic uses 141 of those wide-angle images. Images taken using the red, green and blue spectral filters of the wide-angle camera were combined and mosaicked together to create this natural-color view. This image spans about 404,880 miles (651,591 kilomet

Nebula NGC 3372 in the Carene in false colours - NGC 3372 Carina nebula - Image of the nebula of the Carene (NGC 3372), a very vast region of star formation, obtained by combining light through 3 different filters that highlight oxygen in blue, hydrogen in green, and sulfur in red. The colors also represent different gas temperatures, warm, blue, colder in red. The bright star in the center of the image is Eta Carinae, a super massive star. Image obtained with the Curtis - Schmidt telescope of the Cerro Tololo Observatory. This image shows a giant star - forming region in the southern sky known as the Carina Nebula (NGC 3372), combining the light from 3 different filters tracing emission from oxygen (blue), hydrogen (green), and sulphur (red). The color is also representative of the temperature in the ionized gas: blue is relatively hot and red is cooler. The Carina Nebula is a good example of how very massive stars rip apart the molecular clouds that give birth to them. The bright sta

Barnard's Star Movement - The proper motion of Barnard's star - Barnard's Star is a red dwarf less than six years from Earth in the constellation Ophiuchus. Its proximity makes it move quickly ahead of the other stars. Barnard's star is known for having the most important clean movement. This composite image made from three images taken in 1988 (blue), 1991 (red) and 1993 (green) shows the shift of the star in 15 years. Barnard's Star is red dwarf star approximately 6 light - years away from Earth in the constellation of Ophiuchus Its proper motion is 10.3 arcseconds per year, which remains the largest known proper motion of any star relative to the Sun. The monochrome plates from which this 3 - colour picture were made were taken in 1988 (blue), 1991 (red) and 1993 (green) showing its movement over 15 years

Uranus and three satellites seen by Voyager 2 - Image obtained by the Voyager 2 probe in January 1986 showing the planet Uranus accompanied by the satellites Ariel (top right), Miranda (closest to the planet) and Umbriel (bottom left). This Voyager photograph of Uranus taken in january 1986 is a composite of for images taken by the narrow angle camera. At this range, clouds and other features in the atmosphere as small as 1,370 km. could be detected by Voyager 2. Yet, no such features are visible. This view is toward the illuminated south pole of Uranus. The predominant blue color is the result of atmospheric methane, which absorbs the red wavelengths from incoming sunlight. The spot at the upper left edge of the planet's disk reulted from the removal of a network mark used in making measurments on the photograph. Three of Uranus' five known satellites are visible; Miranda (at far right, closest to the planet), Ariel (next out, at top), and Umbriel (lower left). Titania and Oberon are

Iceland seen from the satellite ENVISAT - Iceland seen by satellite - Iceland covered with snow on 4 October 2008. This Envisat image, acquired on 4 October, features the island of Iceland covered in the first snow of the 2008 winter. More than 11 percent of the island is covered by glaciers. The Vatnajokull glacier, the largest glacier in Europe, is located in the southeast where the white area is more prominent. Reykjavik, the country's capital, is located in the southwest - slightly inland from the boot - shaped peninsula on the bottom left that extends out into the Atlantic Ocean. Brilliant colours of blue - green are visible swirling in the waters off the south and western coasts. These are caused by large concentrations of phytoplankton, which form the basis of the ocean's food chain and have an essential role in the global ecosystem

Remains of the Supernova of Vails - Detail - The Vela supernova remnant - Nearly 12,000 years ago, a massive star exploded in the constellation Vails. This image shows part of the rest of this supernova where the hydrogen atoms appear in red and the oxygen in blue - green. Approximately 11,000 to 12,000 years ago a massive star exploded in the southern constellation of Vela. The matter ejected by the supernova scattered the contents of the star into the surrounding interstellar medium creating shock fronts of multimillion degree gas and high energy particles. The heated matter produces brilliant visible light as well as radio and x - ray emission which will continue for thousands of years until the entire remnant of the dying star completely dissipates into space. This image captures some of that filamentary and gigantic shock in visible light. Hydrogen atoms being excited by atomic collisions glow red, while oxygen appears blue - green

Detail of the nebula Omega (M17) by HST - This Hubble photograph captures a small region within Messier 17 (M17), a hotbed of star formation. M17, also known as the Omega or Swan Nebula, is located about 5500 light - years away in the Sagittarius constellation. The wave - like patterns of gas have been sculpted and illuminated by a torrent of ultraviolet radiation from young, massive stars (which lie outside the picture to the upper left). The glow of these patterns highlights the 3D structure of the gases. The ultraviolet radiation is carving and heating the surfaces of cold hydrogen gas clouds. The image, roughly 3 light - years across, was taken on 29 - 30 May 1999, with Hubble's Wide Field Planetary Camera 2. The colours in the image represent various gases. Red represents sulphur; green, hydrogen; and blue, oxygen

Tokyo night view - Tokyo at Night - Tokyo night view from the International Space Station (ISS) on February 5, 2008. The green blue colour of urban lighting is due to the use of mercury vapour lamps. This nighttime photograph of Tokyo, Japan, was taken by an International Space Station astronaut on February 5, 2008. The heart of the city is brightest, with ribbons of lights radiating outward from the center along streets and railways. The regularly spaced bright spots along one of the ribbons heading almost due west out of the downtown area are probably train stations along a public transit route. The lights of Tokyo are a cooler blue - green color than many other world cities. The color results from the more widespread use of mercury vapor lighting as opposed to sodium vapor lighting, which produces an orange - yellow light

Central region of the elliptical galaxy Centaurus A (NGC 5128) - Central part of the galaxy Centaurus A (NGC 5128) - The galaxy NGC 5128 is located about 13 million years away from Earth in the southern constellation of Centaurus. A broad dark band crosses it in the middle, a probable vestige of a collision with a spiral galaxy. This giant galaxy is a powerful radio source known as Centaurus A. It is an active galaxy whose energy comes from a supermassive black hole. The green dot visible in the dust strip is a supernova, the supernova 1986g. It appears green because the red filter image that made this trichromy image was only taken a year after the event and the supernova had weakened. Image obtained from the 3.9m telescope of Siding Spring, Australia. The nearby radio source Centaurus A (NGC 5128) looks like an elliptical galaxy, crossed by a broad, irregular dust lane. The dark band is probably the remains of a dusty spiral galaxy which is being absorbed by the giant elliptical. One
