Heart of the nebula NGC 3372 in the Carene - Eta Carinae and the Keyhole Nebula - The nebula of the Carene is located about 7000 years - light from the Earth. It is home to many hot stars, including the star Eta Carinae visible in the centre left of the image. Eta Carinae is a supermassive star (100 to 150 times the mass of the Sun). Image obtained by Siding Spring's 3.9m telescope. This wonderfully complex region at the heart of the NGC 3372 nebula was first described in detail by Sir John Herschel in 1838. He saw the bright circular shell visible in the upper part of the picture extending to the south to form a keyhole - shaped nebula. This luminous outline is no longer seen and the southern extension appears only as a dark dust cloud. It seems that the curious, explosively variable star Eta Carinae has enveloped itself in a cocoon of obscuring matter in the years since Herschel's observations and light from the star is no longer able to illuminate the rim of the dust cloud.

Spiral galaxy NGC 4651 in Berenice's Hair - Spiral galaxy NGC 4651 in Coma Berenices - The galaxy NGC 4651 (Arp 189) is located about 50 million years away - light from Earth. The Umbrella Galaxy (NGC 4651 or Arp 189) exhibits a jet like spear that's strikingly coherent and narrow. The structure was previously reported by Boris Vorontsov Velyaminov in 1959 but never interpreted as a stellar tidal stream. This deep image additionally shows a spectacular crescent shaped shell surrounding the east side of the star system that corresponds to the apocenter of the dwarf galaxy. Interestingly, a possible second arc on the western side of the galaxy can also be seen in this image. This feature is less obvious because it's partially hidden by the galaxy's disk and suggests we are observing a moderately inclined structure projected into the halo of NGC 4651. This image was produced by combining an hour of exposure through the Isaac Newton Telescope, located on the Spanish island of La Palma, wit

Mars and Zodiacal Light - The Zodiacal Light with Mars - In the middle up, the bright spot is the planet Mars, in the constellation Gemeaux. Below, the zodiac light. The zodiacal light comes from the reflection of the Sun's light on the countless interplanetary dust; it draws the plan of the Solar System. September 20, 2009. The Zodiacal light is visible here as a large diffuse triangular - shaped cone of light rising along the ecliptic, which is tilted a bit to the right. Its base stretches from Leo on the left to the head of Hydra on the right. It goes up through Cancer and into Gemini where it crosses the Milky Way. The planet Mars was also located in Gemini when this photo was taken. The Zodiacal light is composed of fine particles of dust in orbit around the Sun. It is visible because of sunlight scattered by the particles. These particles have sizes between a couple of micrometers and a few millimeters. From the mid - northern latitudes, the Zodiacal light is most easily visible

Star formation in the nebula NGC 2467 - Star - forming region NGC 2467 - Star formation in the nebula NGC 2467, located approximately 17,000 years ago - light from Earth in the southern constellation of Stern. Image obtained by the Hubble Space Telescope in 2004. A colourful star - forming region is featured in this stunning new NASA/ESA Hubble Space Telescope image of NGC 2467. Looking like a roiling cauldron of some exotic cosmic brew, huge clouds of gas and dust are sprinkled with bright blue, hot young stars. Strangely shaped dust clouds, resembling spilled liquids, are silhouetted against a colourful background of glowing. Like the familiar Orion Nebula, NGC 2467 is a huge cloud of gas - - mostly hydrogen - - that serves as an incubator for new stars. It is located about 17,000 light years away in the southern constellation of Puppis. This picture was created from images taken with the Wide Field Channel of the Advanced Camera for Surveys through three different filters (F550M, F6

Interacting galaxies Markarian 533 - Interacting galaxies Markarian 533 - The galaxy NGC 7674 (Markarian 533 or Arp 182) is located about 400 million years ago - light from Earth in the constellation Pegase. It is the most important member of a group of galaxies called Hickson 96 (HCG 96). This spiral galaxy seen from the front is in interaction with other companion galaxies. It has an active core. Image obtained by the Hubble Space Telescope on June 9, 2002. NGC 7674 (seen just above the center), also known as Markarian 533, is the brightest and largest member of the so - called Hickson 96 compact group of galaxies, consisting of four galaxies. This stunning Hubble image shows a spiral galaxy nearly face - on. The central bar - shaped structure is made up of stars. The shape of NGC 7674, including the long narrow streamers seen to the left of and below the galaxy can be accounted for by tidal interactions with its companions. NGC 7674 has a powerful active nucleus of the kind known as

Barree spiral galaxy NGC 1483 in Dorado - Barred spiral galaxy NGC 1483 in Dorado - NGC 1483 is a barree spiral galaxy located about 60 million years ago - light in the southern constellation of Dorado. Image obtained by the Hubble Space Telescope (HST). NGC 1483 is a barred spiral galaxy located in the southern constellation of Dorado. The nebulous galaxy features a bright central bulge and diffuse arms with distinct star - forming regions. In the background, many other distant galaxies can be seen. The constellation Dorado is home to the Dorado Group of galaxies, a loose group comprising an estimated 70 galaxies and located some 62 million light - years away. The Dorado group is much larger than the Local Group that includes the Milky Way (and which contains around 30 galaxies) and approaches the size of a galaxy cluster. Galaxy clusters are the largest groupings of galaxies (and indeed the largest structures of any type) in the Universe to be held together by their gravity. Barred s

Cl0024+17 galaxy cluster Cl0024+17 - Galaxy cluster Cl0024+17 - Cl0024+17 galaxy cluster located about 5 billion years ago - light in the constellation Pisces. This image reveals to us, by a gravitational mirage effect, the deformed image of a galaxy, located behind the cluster at a distance of about 10 billion years - light from the Earth. By studying this gravitational mirage, astronomers discovered the presence of black matter around this cluster. Image obtained by the Hubble space telescope in November 2004 with the ACS camera. An international team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a ghostly ring of dark matter that was formed long ago during a titanic collision between two massive galaxy clusters. It is the first time that a dark matter distribution has been found that differs substantially from the distribution of ordinary matter.

It is located in the constellation of Taurus (the Bull), close to the central plane of our Milky Way galaxy. It appears to be a small, rather isolated, region of star formation and one might assume that the effects of fierce ultraviolet radiation from bright young stars probably were the cause of the eye - catching shapes of the gas. However, the bright boomerang - shaped feature may tell a more dramatic tale. The interaction of a high velocity young star and the cloud of gas and dust may have created this unusually sharp - edged bright arc.

Abell 2218 galaxy cluster in the Dragon - Gravitational lenses in the galaxy cluster Abell 2218 - The Abell 2218 galaxy cluster is located about 2 billion years ago - light from Earth in the constellation of the Dragon. It is so massive that its gravity curved and amplifies the light from other galaxies located behind it. Thus, these galaxies appear on this cliche obtained by the Hubble space telescope in the form of arcs. Abell 2218 resides in the constellation Draco, some 2 billion light - years from Earth. The cluster is so massive that its enormous gravitational field deflects light rays passing through it, much as an optical lens bends light to form an image. This phenomenon, called gravitational lensing, magnifies, brightens, and distorts images from faraway objects. The cluster's magnifying powers provides a powerful “” zoom lens”” for viewing distant galaxies that could not normally be observed with the largest telescopes. This useful phenomenon has produced the arc - shaped pa

Group of Galaxies HCG 31 - Hickson Compact Group 31 - This group of interacting galaxies is located 166 million years of light from Earth in the constellation Eridan. Dwarf galaxies are merging causing intense star formation. This long fusion process will lead to the birth of a large elliptical galaxy. Image obtained by the Hubble Space Telescope on August 8, 2006. These four dwarf galaxies waited billions of years to come together, setting off a fireworks show as thousands of new star clusters come to life. The distorted galaxies are quickly producing massive, hot, young stars that are pumping out ultraviolet radiation, heating up surrounding gas clouds, and causing them to glow. Such encounters between dwarf galaxies are normally seen billions of light - years away and therefore occurred billions of years ago. But these galaxies, members of Hickson Compact Group 31, are relatively nearby, only 166 million light - years away. In this image, taken by Nasa's Hubble Space Telescope, the

Due to this snow cover and a relatively low illumination angle of the sun, the ranges and valleys of the mountains stand out in the image. Much of the whiteness seen in the top of the image is cloud cover, but fog is visible in the valleys such as the Rhine. The Alps - central Europe's major mountain range - extend some 1,200 km through France, Switzerland, Italy and Austria and down through Slovenia, Croatia, Bosnia and Herzegovina, Serbia and Montenegro and Albania as the Dinaric Alps. The Alps occupy an area of about 200,000 km an

Titan, Saturn satellite seen by Cassini: Visible and infrared composite image of Titan taken by the Cassini probe on September 12, 2013. View of methane and ethane lakes. - This false-color mosaic, made from infrared data collected by Nasa's Cassini spacecraft, reveals the differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn's largest moon. Titan is the only other place in the solar system that we know has stable liquid on its surface, though its lakes are made of liquid ethane and methane rather than liquid water. While there is one large lake and a few smaller ones near Titan's south pole, almost all of Titan's lakes appear near the moon's north pole - Scientists mapped near-infrared colors onto the visible color spectrum. Red in this image was assigned a wavelength of 5 microns (10 times longer than visible light), green 2.0 microns (four times longer than visible light), and blue 1.3 microns (2.6 times longer than visible light) - The orange

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. The Hubble photograph of NGC 6369, captured with the Wide Field Planetary Camera 2 (WFPC2) in February 2002, reveals remarkable details of the ejection process that are not visible from ground - based telescopes because of the blurring produced by the Earth's atmo
