Hemispheric View of Venus
... centered roughly on 0 degree latitude and longitude, and with a neutral tone elsewhere (primarily near the south pole). The composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation.

Gaps in the elevation data from the Magellan radar altimeter were filled with altimetry from the Venera spacecraft and t...

Color Image of Multiple P/Shoe
... Planetary Camera. Eight impact sights are visible. From left to right are the E/F complex (barley visible on the edge of the planet), the star shaped H site, the impact sites for tiny N, Q1, small Q2, and R, and on the far right limb the D/G complex. The D/G complex also shows extended haze at the edge of the planet. The features are rapidly evolving on timescales of days. The sma...

Jupiter's Inner Satellites and
... Satellites and Ring Components
Date: 15 Sep 1998
This schematic cut-away view of the components of Jupiter's ring system shows the geometry of the rings in relation to Jupiter and to the small inner satellites, which are the source of the dust which forms the rings.

The innermost and thickest ring, shown in gray shading, is the halo that ends at the main ring...

Our Solar System

An artist's impression of our solar system with separate representations of scale and size.



From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects planets, meaning wanderers, and named them after...

Asteroids
... images obtained by NASA's NEAR mission immediately after the spacecraft's insertion into orbit.



Asteroids are rocky, airless worlds that orbit our Sun, but are too small to be called planets. Tens of thousands of these 'minor planets' are gathered in the main asteroid belt, a vast doughnut-shaped ring between the orbits of Mars and Jupiter. Asteroids that ...

Featured Mission: Curiosity
Curiosity, a robotic rover about the size of a small SUV, is designed to find whether the Red Planet ever was -- or is still today -- an environment suitable for life. The rover will follow on the work of the Sojourner, Spirit and Opportunity...

Prometheus Rising Through Satu
... look like a shadow or a trail blazed by sweeping up material, computer simulations indicate that the dark streak is better understood as an empty path pulled away by the gravity of Saturn's small moon. The particles don't follow Prometheus so much as glide sideways past where Prometheus used to be. One dark streamer is created during each pass of Prometheus through the F-ring that...

The Necklace Nebula
The Necklace Nebula

Explanation: The small constellation Sagitta sports this large piece of cosmic jewelry, dubbed the Necklace Nebula. The newly discovered example of a ring-shaped planetary nebula is about 15,000 light-years distant. Its bright ring with pearls of glowing gas is half a light-year across. Planetary nebulae are created by sun-like stars in a final phase...

Comet Hartley 2 Flyby
... approach distance was about 700 kilometers. In fact, this encounter was the fifth time a spacecraft from planet Earth has imaged a comet close-up. But Hartley 2's nucleus is definitely the smallest one so far, its long axis spanning only about 2 kilometers (1.2 miles). Though Hartley 2 is small, these stunning images showing jets of dust and gas indicate an impressively active sur...
