Pluto - Information on Pluto
The former 9th planet from the sun, Pluto was declared a dwarf plane by the International Astronomical Union (IAU) at the 26th General Assembly in August of 2006.

Pictures of Venus - Akna Mountains
The Akna Mountains form the western edge of Lakshmi Planum. Wanda, the giant crater on the upper right, has a diameter of 18 km (11 mi). While Wanda doesn't appear to have been deformed by tectonics, material from the Akna Mountains appears to have collapsed into it. The area represented by this image is about 200 km (124 mi) long by 125 km (78 mi) wide. Page 39.

Pictures of Venus - Arachnoids
Named by the Soviets for their spider and cobweb-like appearance, arachnoids are one of the more remarkable features found on Venus. They are 50 to 230 km (30 to 138 mi) diameter circular structures, with a central volcanic feature surrounded by a complex network of fractures. Arachnoids are similar in form but generally smaller than coronae. Page 38.

Pictures of Venus - Craters in Transition
Magellan's radar system detected few impact craters in the process of being resurfaced by volcanism. Alcott is the largest of these craters in transition, with a diameter of 63 km (39 mi). The trough-like depression (lower left) is a rille through which lava once flowed. A remnant of rough radial ejecta is preserved outside the crater's southeast rim. The presence of partially lava-flooded craters such as this is important to our understanding of the rate of resurfacing on Venus by volcanism. Page 31.

Pictures of Venus - Danu Mountains
The Danu Mountains bound Lakshmi Planum to the south. Because of the steep slopes, the local relief in the area (2-3 km/1-2 mi), and the effects of radar geometry, the fault- bounded troughs appear to zigzag through the area when in reality, they are likely straight when viewed from above. The large volcanic dome is 20 km (12 mi) in diameter and was deformed when the Danu Mountains were created. Page 30.

Pictures of Venus - Dark Halos
Impact craters such as Crater Carson shown here are frequently surrounded by radar-dark halos. Several of these special craters have halos that are parabolic in shape and are very long, extending hundreds of kilometers to the west. The darkness of the emissivity data indicates a smooth surface, leading scientists to believe that halos may be thick, smooth sediment deposits formed when incoming projectiles crashed into the surface. The black strips represent missing data. Page 29.

Pictures of Venus - Domical Hills
Seven circular domes can be seen on the eastern edge of Alpha Regio. They average 25 km (15 mi) in diameter with maximum heights of 750 m (2475 ft). Some scientists believe they are the result of eruptions of thick lava that flowed from a vent on level ground, resulting in an even lateral pattern of lava. The concentric and radial fracture pattern on the surface of the domes suggests that lava welled up inside the domes, causing the surface to stretch. Page 28.

Pictures of Venus - Eastern Lakshmi
Lava flows blanket the flat plains region of eastern Lakshmi. The dark flows most likely represent smooth flows similar to pahoehoe flows on Earth, while the brighter areas are rougher flows resembling Earth's aa flows. Three dark splotches mark the tops of these lava flows. Because of the thick atmosphere surrounding Venus, small impactors break up before they hit the surface. The fragments are deposited over the surface and produce the dark splotches seen here. Page 27.

Pictures of Venus - Fault-Bounded Troughs
The large fault-bounded trough in the center of the image was nicknamed Gumby (after an animated cartoon figure) by Magellan scientists. Located in the Lavinia region at the intersection of two tectonic trends, Gumby measures 5 km (3 mi) wide and 100-200 m (.06 - .1 mi) deep. An example of one of the trends is the bright lines running E-W through Gumby's head. A second example is the bright lines running SW to NE through Gumby's legs and hips. Page 26.

Pictures of Venus - Highlands
Several tectonic events formed this complex terrain, which is part of the interior of Ovda Regio. An underlying fabric of ridges and valleys lies NE-SW. These ridges are spaced 10-20 km (6-12 mi) apart and may have been caused by compression of the crust at right angles to the ridge. The ridges are cut by bright features extending NW-SE. Page 22.

Pictures of Venus - Lakshmi Planum
The southern scarp and basin province of western Ishtar Terra are portrayed in this vertically exaggerated 3-dimensional perspective view. Western Ishtar Terra is about the size of Australia and is a major focus of Magellan investigations. The highland terrain is centered on a 2.5 km to 4 km-high (1.5 mi to 2.5 mi-high) plateau, Lakshmi Planum, which can be seen in the distance at the right. Page 20.

Pictures of Venus - Large Impact Crater
A large impact crater about 30 km (19 mi) in diameter is surrounded by a fresh ejecta blanket. The extreme brightness of the blanket is due to its roughness and its ability to scatter the radar signals that are used to collect these images. Scientists believe that the missing section of the ejecta blanket is due to an atmospheric blast that followed the impactor as it crashed through the Venusian atmosphere. Page 19.

Pictures of Venus - Largest Crater
Crater Mead is the largest known crater on Venus. Named after Margaret Mead, the American anthropologist, it measures 280 km (168 mi) in diameter and is located north of Aphrodite Terra and east of Eistla Regio. Classified as a multi-ring crater, Mead's innermost ring is thought to be the rim of the original crater cavity. Page 18.

Pictures of Venus - Lava flows
This mosaic highlights a system of east-trending, radar-bright and dark lava flows that collide with and breach a north-trending ridge belt (left of center). Upon breaching the ridge belt, the lava pooled, forming a radar-bright deposit approximately 100,000 square km (right side of image). The source of the lava is the Corona Derceto, which lies about 300 km (186 mi) west of the scene. The bright and dark bars extending from top to bottom are artifacts of image processing. Page 17.

Pictures of Venus - Ovda Regio
The tectonic fabric of this region of Ovda Regio trends predominantly east-west. The large radar-dark areas are probably tectonically formed basins that have been filled in by fluid lava flows, thus presenting a smooth surface to the Magellan radar system. Page 14.

Pictures of Venus - Peak-Ring Crater
This 54-km (32-mi) diameter crater is the size at which craters on Venus begin to possess peak-rings instead of a single central peak. The floor of Barton crater is flat and radar-dark, indicating possible infilling by lava flows sometime following the impact. Barton's central peak-ring is discontinuous and appears to have been disrupted or separated during or following the cratering process. Page 12.

Pictures of Venus - Recent Volcanism
This false-color view of the volcano Sif Mons was generated from Magellan SAR data and existing altimetry data. The image shows a region of the volcano just below the summit of the peak. A series of bright and dark lava flows is visible in the foreground. The brightest flows, which are relatively rough, are associated with the most recent volcanism in the region. Page 10.

Pictures of Venus - Ridges and Troughs
On this bright, lineated terrain Alpha Regio is a series of troughs, ridges, and faults running in every direction. The lengths of these features range from 10 km (6.3 mi) to 60 km (37 mi). The elevation of Alpha Regio varies over a range of 4 km (2.5 mi). Low-lying areas appear dark in the radar images and may be filled with lava. Volcanoes appear as bright spots on the smooth plains. Notice the large volcano in the upper right. Page 9.

Pictures of Venus - Selu Corona
Located in Lada Terra, Selu Corona measures 350 km (210 mi) in diameter. Coronae are circular to elliptical features marked by a ring of concentric ridges, and are thought to result from the flow of heat in the planet's interior. As hot material rises, it weakens the upper layers of the crust, causing the surface to dome upwards. Page 7.

Pictures of Venus - Tributary-Like Branches
In a region near Hestia Rupes on the NW corner of Aphrodite Terra lies a complex network of narrow (. Page 4.

Pictures of Venus - Twin Summit
Located in the Atla Regio region of Venus is Sapas Mons. The sides of the volcano are covered with numerous overlapping lava flows, many of which appear to have originated along the sides of the volcano rather than from its double summit. This type of eruption is common of large shield volcanoes on Earth, such as those found in Hawaii. Color was artificially added to this image and is based on the colors that the Soviet Venera 13 and 14 spacecraft observed in the 1970s. Page 3.

Pictures of Venus - Venus in Color
The bluish hue of Venus is an effect of the colorization technique used to enhance subtle contrasts in cloud patterns and indicates that this image was taken through a violet filter. Features in the sulfuric acid clouds near the top of the planet's atmosphere are most prominent in violet and ultraviolet light. This image shows the east to west cloud banding and the brighter polar hoods . The features are embedded in winds that flow from east to west at about 370 kph (230 mph). Page 2.

This image is a mosaic image taken by the navigation camera on the Mars Exploration Rover Spirit shows a 360 degree panoramic view of the rover on the surface of Mars. Page 20.

Spirit Back in Action
Spirit temporarily stopped communicating Jan. 22; the problem was later diagnosed as a memory-management issue. Engineers regained partial control of the spacecraft within days and reformatted Spirit's flash memory. NASA's Spirit has returned to full health and resumed doing things never attempted on Mars before. Page 15.

Spirit Enters the Martian Atmosphere
The lander came streaking in through the martian atmosphere, going about 12,000 miles per hour. Given atmospheric friction, the outside surface of the heat shield was as hot as the surface of the sun (1,447 degrees Celsius, or 2,637 degrees Fahrenheit), but the rover was protected by the heat shield and will stay at about room temperature inside the lander. The heat shield also aerodynamically acts as the first

Spirit Parachute Deploys
About four minutes after entering Mars's atmosphere, the spacecraft slows to about 1,000 miles per hour and is only 30,000 feet above the martian surface. At this point, a supersonic parachute is deployed. The parachute is based on the designs and experience of those used in the Viking and Pathfinder missions. The parachute for this mission is about 40% larger than Pathfinder's, and is made of two durable lightweight fabrics (polyester and nylon). Page 9.

Pictures of the Sun - Coronal Loops
Extending above the photosphere or visible surface of the Sun , the faint, tenuous solar corona can't be easily seen from Earth, but it is measured to be hundreds of times hotter than the photosphere itself. What makes the solar corona so hot? Astronomers have long sought the source of the corona's heat in magnetic fields which loft monstrous loops of solar plasma above the photosphere. Page 2.
