Position Right ascension — analogous to longitude — is one component of an object's position. Position Declination — analogous to latitude — is one component of an object's position. Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units AU. Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky. About The Data Data Description Proposal: A description of the observations, their scientific justification, and the links to the data available in the science archive. Science Team: The astronomers who planned the observations and analyzed the data.
Instrument The science instrument used to produce the data. Exposure Dates The date s that the telescope made its observations and the total exposure time. Filters The camera filters that were used in the science observations. Saturn's small moon Pan casts a long shadow across the A ring in this image captured by the Cassini spacecraft a few days after the planet's August equinox.
Pan 28 kilometers, or 17 miles ac Pan's Shadow. Bands and Swirls in Infrared. This view of the twilight sky and Martian horizon taken by NASA's Curiosity Mars rover includes Earth as the brightest point of light in the night sky. The Cassini spacecraft's close flyby of Epimetheus in December returned detailed images of the moon's south polar region.
The view shows what might be the remains of a large impact crater co Epimetheus Revealed. NASA's Dawn spacecraft shows Sekhet Crater on Ceres has prominent shadows accentuating its central peak and mounds of material that have slumped downward from its walls. These features likely resulted when the crater partly collap This artist's painting of the south polar region of Saturn's tiny moon Enceladus shows massive jets of water ice being blasted into space.
The moon's lack of atmosphere and low gravity prevents the The Fountains of Enceladus. Saturn's moon Enceladus drifts before the rings, which glow brightly in the sunlight. Saturn's softly glowing rings shine in scattered sunlight. Rings Aglow. With its excess warmth, water ice jets and huge vapor plume laced with simple organic materials, Enceladus is an important part of the quest to understand environments compatible with the chemistry The crater features a network of canyon-like features.
Dawn XMO2 Image This extreme false-color view of Mimas shows color variation across the moon's surface. To create this false-color view, ultraviolet, green and infrared images were combined into a single picture Multicolor Mimas.
Rings and More Rings. The Cassini spacecraft looks toward the unilluminated side of Saturn's rings to spy on the moon Pan as it cruises through the Encke Gap. This view looks toward the rings from about 13 degrees abov Saturn also appears brighter when the rings are angled such that they are more visible.
For example, during the opposition of 17 December , Saturn appeared at its brightest due to a favorable orientation of its rings relative to the Earth, [] even though Saturn was closer to the Earth and Sun in late From time to time, Saturn is occulted by the Moon that is, the Moon covers up Saturn in the sky.
As with all the planets in the Solar System, occultations of Saturn occur in "seasons". Saturnian occultations will take place monthly for about a month period, followed by about a five-year period in which no such activity is registered. The Moon's orbit is inclined by several degrees relative to Saturn's, so occultations will only occur when Saturn is near one of the points in the sky where the two planes intersect both the length of Saturn's year and the Jump to content Navigation.

- Saturn color
An image of Saturn taken by the Cassini spacecraft. Are they solid like the CD you used to make your model? Or are they made of many particles dancing in formation around the planet? They have revealed many surprising things about Saturn's rings. The small color differences in Saturn's rings have been enhanced in this picture from Voyager 2 data. Credit: NASA. Over 60 bright and dark ringlets show up in this color enhanced image from Voyager 2 data.
The rings are about , kilometers , miles wide. That's the distance from the Earth to the Moon! But the rings are as little as meters feet thick. They range from particles too tiny to see to "particles" the size of a bus. Scientists think they are icy snowballs or ice covered rocks. Artist's concept of Cassini diving between Saturn and its innermost ring.
The Cassini spacecraft arrived at Saturn in July It orbited Saturn for 13 years, studying Saturn, its rings, and its moons much more thoroughly than the earlier spacecraft could. Cassini also carried a probe, called Huygens HOY-guns , that parachuted into the atmosphere of Saturn's giant moon Titan.
Huygens sent back amazing information and images from this strange world whose surface we have never seen. Cassini and Huygens made many exciting discoveries. In September , Cassini ended its mission with a planned plunge into Saturn's atmosphere. A view of Saturn's rings, as seen by the Cassini spacecraft.
This series of photos was taken by the Hubble Space Telescope from through You can see how Saturn's rings seem to change, but it is only because our angle of view changes. Why does Saturn have rings?
What are Saturn's rings made of? There are actually many rings—maybe to There are also gaps in the rings. If you liked this, you may like: Make a CD Saturn.
