Richat structure - Mauritania - satellite view - Richat structure, Mauritania, seen by satellite - Richat structure is a geological formation of volcanic origin in Mauritania. This “eye” measures 50 km in diameter. This image is a combination of an image obtained by the Landsat satellite in 1987 and a radar image obtained from the Space Shuttle (SRTM) in 2000. The relief is exaggerated by about 6 times. The picture covers an area of 68 km by 112 km. This prominent circular feature, known as the Richat Structure, in the Sahara desert of Mauritania is often noted by astronauts because it forms a conspicuous 50 - kilometer - wide (30 - mile - wide) bull's - eye on the otherwise rather featureless expanse of the desert. Initially mistaken for a possible impact crater, it is now known to be an eroded circular anticline (structural dome) of layered sedimentary rocks. Extensive sand dunes occur in this region and the interaction of bedrock topography, wind, and moving sand is evident in this

Colliding spiral galaxies NGC 2207 and IC 2163 - Colliding galaxies NGC 2207 and IC 2163 - The galaxies NGC 2207 (left) and IC 2163 (right) form a pair of colliding galaxies approximately 114 million light years away. Currently IC 2163 is moving away from NGC 2207, but it is likely that within several billion years these two galaxies will eventually merge into a single massive galaxy. Image obtained by the Hubble Space Telescope in 1998. The larger and more massive galaxy is cataloged as NGC 2207 (on the left in the Hubble Heritage image), and the smaller one on the right is IC 2163. Strong tidal forces from NGC 2207 have distorted the shape of IC 2163, flinging out stars and gas into long streamers stretching out a hundred thousand light - years towards the right - hand edge of the image. The calculations indicate that IC 2163 is swinging past NGC 2207 in a counterclockwise direction, having made its closest approach 40 million years ago. However, IC 2163 does not have sufficient ener

Center of the spiral galaxy M51 in Hunting Dogs - Spiral galaxy M51 in Canes Venatici - The spiral galaxy M51 (NGC 5194) is located about 31 million years away - light from Earth. This galaxy is double; two galaxies interact: the largest, NGC 5194, the smallest NGC 5195. This image obtained by the Hubble Space Telescope in 2005 shows the central region of NGC 5194 showing the star-forming zones in red. This image of the cenral area of M51 was taken with the Hubble space telescope in 2005. Located in the constellation of Canes Venatici, the “” hunting dogs””, M51 consists of the large spiral galaxy NGC 5194 and its smaller companion NGC 5195 (out of field). The reddish areas are nebulae in the galaxy in which stars are rapidly forming. M51 is approximately 31 million light years away and over 65,000 light years in diameter

Spiral galaxy of Sombrero M104 in the Virgin - The Sombrero galaxy (M104) in Virgo - The spiral galaxy M104 (NGC 4594, Sombrero galaxy) is located about 28 million years ago - light. Assembled 6 images obtained with the Hubble Space Telescope in May and June 2003. The “” Sombrero”” is located in the constellation Virgo.

This galaxy is double; a second galaxy at the bottom right of the image collides with it, causing star formation. Image obtained by the Hubble Space Telescope in 1996. A large spiral galaxy, with its nucleus still intact, peers at the smaller passing galaxy (almost out of the field of view at lower right). These galaxies did not merely interact gravitationally as they passed one another, they actually collided. When galaxies collide, the stars that normally comprise the major portion of the luminous mass of each of the two galaxies will almost never collide with each other but will pass rather freely between each other with little damage. This occurs because the physical size of individual stars is tiny compared to their typical separations, making the chance of physical encounter relatively small. In our own Milky Way galaxy, th

Saturn and satellites seen by the Hubble space telescope - Saturn rings edge - on with satellites - Saturn observed by the Hubble space telescope on February 24, 2009 when the Earth is in the same plane as the rings, seen by the slice. This phenomene occurs every 15 years. This sequence of images taken for just over three hours shows the movement from left to right of four satellites in front of the planet. From left to right on the top image we see the satellites Enceladus, Dione (the brightest ice satellite), Mimas and the largest satellite, Titan, orange. This sequence of images captures the parade of several of Saturn's moons transiting the face of the gas giant planet from left to right during more than three hours. This is a rare event because the rings are tilted edge on to Earth every 15 years. The top frame captures the giant moon Titan and its shadow near Saturn's northern polar hood. Tiny Mimas and its shadow have just entered the left limb of Saturn, slightly above the ring
