Galaxy Centaurus A (NGC 5128) x-ray view - radio - visible - Galaxy Centaurus A in different wavelengths - false-coloured view of the 30,000-year long jet - light escaping from the nucleus of the Centaurus A galaxy where a massive black hole is suspected. On this composite image obtained in X, radio, and visible, two large X-emission arcs surround this jet over a diameter of 25,000 years - light. These hot arcs could be the result of a gigantic explosion that occurred 10 million years ago in the nucleus of the galaxy. The galaxy NGC 5128 is located about 13 million light years away from Earth. A composite X - ray (blue), radio (pink and green), and optical (orange and yellow) image of the galaxy Centaurus A presents a stunning view of a galaxy in turmoil. A broad band of dust and cold gas is bisected at an angle by opposing jets of high - energy particles blasting away from the supermassive black hole in the nucleus. Two large arcs of X - ray emitting hot gas were discovered in the out

Elliptical galaxy NGC 1132 and distant galaxies - Elliptical galaxy NGC 1132 and distant galaxies - The galaxy NGC 1132 is about 320 million years - light from Earth in the constellation Eridan. This giant elliptical galaxy is surrounded by a vast halo of dark matter; it and the dwarf galaxies surrounding it are probably the rest of a larger group of galaxies that have merged over time. In the background, many more distant galaxies are visible. Composite of images obtained by the Hubble Space Telescope in 2005 and 2006. The elliptical galaxy NGC 1132, seen in this image from Hubble space telescope, belongs to a category of galaxies called giant ellipticals. NGC 1132, together with the small dwarf galaxies surrounding it, are dubbed a fossil group” as they are most likely the remains of a group of galaxies that merged together in the recent past. In visible light NGC 1132 appears as a single, isolated, giant elliptical galaxy, but this is only the tip of the iceberg. Scientists have fou

Elliptical galaxy NGC 1275 in Persee - Elliptical galaxy NGC 1275 in Perseus - This image obtained by the Hubble space telescope in 1995 shows a system of two colliding galaxies; in the foreground, a spiral galaxy seen almost from the edge, with many stars forming in the background, a giant, very bright elliptical galaxy, special because it has a spiral structure in its center. Its core probably houses a black hole. NGC 1275 is located about 230 million years ago - light; it belongs to the large cluster of galaxies of Persee. These images, taken with Hubble's Wide Field Planetary Camera 2 (WFPC2), show traces of spiral structure accompanied by dramatic dust lanes and bright blue regions that mark areas of active star formation. Detailed observations of NGC 1275 indicate that the dusty material belongs to a spiral system seen nearly edge - on in the foreground. The second galaxy, lying beyond the first, is actually a giant elliptical with peculiar faint spiral structure in its nucleus.

Spiral galaxy NGC 4622 in Centaurus - Spiral galaxy NGC 4622 in Centaurus - The spiral galaxy NGC 4622 is located 111 million light years ago in the southern constellation of Centaurus. The image obtained by the Hubble Space Telescope in May 2001 shows regions filled with new stars in blue. Astronomers have observed that, unlike other known spiral galaxies, it is the outer arms of this galaxy that rotate the whole, rotating in the same direction as the center; moreover, an inner arm of the galaxy would rotate in the opposite direction. A small galaxy absorbed by NGC 4622 could be responsible for this anomaly. NGC 4622 resides 111 million light - years away in the constellation Centaurus. The image taken in May 2001 with Hubble's Wide Field Planetary Camera 2 shows NGC 4622 and its outer pair of winding arms full of new stars (shown in blue).

Interacting galaxies NGC 1614 - Interacting galaxies NGC 1614 - The galaxy NGC 1614 is located about 200 million light years away from Earth in the southern constellation of Eridan. This system is composed of interacting galaxies. Image obtained by the Hubble Space Telescope on August 13, 2002. The galaxy system NGC 1614 has a bright optical center and two clear inner spiral arms that are fairly symmetrical. It also has a spectacular outer structure that consists principally of a large one - sided curved extension of one of these arms to the lower right, and a long, almost straight tail that emerges from the nucleus and crosses the extended arm to the upper right. The galaxy appears to be the result of a tidal interaction and the resulting merger of two predecessor systems. The system has a nuclear region of quasar - like luminosity, but shows no direct evidence for an active nucleus. It is heavily and unevenly reddened across its nucleus, while infrared imaging also shows a ridge of d

This pair of interacting galaxies is composed of NGC 6621 on the left and NGC 6622 on the right. NGC 6621 is the largest of the two galaxies. The collision, seen here about 100 million years later, caused intense star flames. Image obtained by the Hubble Space Telescope on 15 March 1999. NGC 6621/2 (VV 247, Arp 81) is a strongly interacting pair of galaxies, seen about 100 million years after their closest approach. It consists of NGC 6621 (to the left) and NGC 6622 (to the right). NGC 6621 is the larger of the two, and is a very disturbed spiral galaxy. The encounter has pulled a long tail out of NGC 6621 that has now wrapped behind its body. The collision has also triggered extensive star formation between the two galaxies. Scientists believe that Arp 81 has a richer collection of young massive star clusters than the notable Antennae

This image was obtained by the Hubble Space Telescope in September 2004. NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. At Hubble's resolution, a myriad of fine details, some of which have never before been seen, is seen throughout the galaxy's arms, disk, bulge, and nucleus. Blue and red supergiant stars, star clusters, and star - forming regions are well resolved across the spiral arms, and dust lanes trace out fine structures in the disk and bar.

This false - color image of Saturn's main rings was made by combining data from multiple star occultations using the Cassini ultraviolet imaging spectrograph. During occultations, scientists observe the brightness of a star as the rings pass in front of the star. This provides a measurement of the amount of ring material between the spacecraft and the star. Cassini has given scientists the most detailed view yet of Saturn's densely packed B ring. Cassini found that this part of the rings is densely packed with clumps, called self - gravity wakes, separated by almost empty gaps. These clumps in Saturn's B ring are neatly organized and constantly colliding, which surprised scientists.

This dune field formed near the base of the North Polar cap. Dunes require a source of loose particulate material to form. The source of the northern dune fields around the polar cap may be from the layers of dusty ice that are eroded by strong polar winds. This image was taken during the Martian northern summer, so there is no frost present on the dunes. The dunes closest to the base of the polar cap are long and parallel, indicating strong winds from the direction of the cap. As they get farther away from the polar cap, they start to form more crescent shaped dunes, called barchan dunes.

These different layers of ice and girders correspond to climatic variations over the last ten thousand years. Image obtained on 18 April 2016 by the HIRISE camera on board the Mars Reconnaissance orbiter probe. HIRISE is a 50 cm telescope that observes visible and near infrared. At the edge of Mars' permanent North Polar cap, we see an exposure of the internal layers, each with a different mix of water ice, dust and dirt. These layers are believed to correspond to different climate conditions over the past tens of thousands of years. When we zoom in closer, we see that the distinct layers erode differently. Some are stronger and more resistant to erosion, others only weakly cemented. The strong layers form ledges

Spiral galaxies NGC 3314 A and B in Hydra - Galaxy pair NGC 3314 in Hydra - NGC 3314 is a pair of spiral galaxies distant about 140 million years - Earth light. These galaxies are not interacting but just perfectly aligned in front of each other from Earth. Through an extraordinary chance alignment, a face - on spiral galaxy lies precisely in front of another larger spiral. This line - up provides us with the rare chance to visualize dark material within the front galaxy, seen only because it is silhouetted against the object behind it. NGC 3314 lies about 140 million light - years from Earth, in the direction of the southern hemisphere constellation Hydra. The bright blue stars forming a pinwheel shape near the center of the front galaxy have formed recently from interstellar gas and dust. In many galaxies, interstellar dust lies only in the same regions as recently formed blue stars. However, in the foreground galaxy, NGC 3314a, there are numerous additional dark dust lanes that are

Planetary nebula NGC 5189 in the Fly - NGC 5189 - Planetary nebula in Musca - This nebula is located about 3000 light years from Earth in the southern constellation of Fly. Image obtained by the Hubble Space Telescope (HST). The colors used in this image correspond to the emissions of different gases: sulfur in green, hydrogen in orange and oxygen in blue. Hubble Space Telescope have photographed a festive - looking nearby planetary nebula called NGC 5189. Planetary nebulae represent the final brief stage in the life of a medium - sized star like our Sun. While consuming the last of the fuel in its core, the dying star expels a large portion of its outer envelope. This material then becomes heated by the radiation from the stellar remnant and radiates, producing glowing clouds of gas that can show complex structures, as the ejection of mass from the star is uneven in both time and direction. This image was taken with Hubble's Wide Field Camera 3 on October 8, 2012, in filters tuned to

M87 elliptical galaxy in Virgo - M87 elliptical galaxy in Virgo - The M87 galaxy (NGC 4486) is 54 million years ago - light from Earth, in the heart of the Virgin's cluster. This image is a composite obtained in X-rays, radio and visible. Gas material is ejected from the heart of the galaxy. A supermassive black hole would have caused this jet. This image is a composite of visible (or optical), radio, and X - ray data of the giant elliptical galaxy, M87. M87 lies at a distance of 54 million light years and is the largest galaxy in the Virgo cluster of galaxies. Bright jets moving at close to the speed of light are seen at all wavelengths coming from the massive black hole at the center of the galaxy. It has also been identified with the strong radio source, Virgo A, and is a powerful source of X - rays as it resides near the center of a hot, X - ray emitting cloud that extends over much of the Virgo cluster. The extended radio emission consists of plumes of fast - moving gas from the j
