Pale Blue Dot Shines In Cassini, MESSENGER Images
2013-07-23 08:37:16

It might look like just one pale blue dot among millions of other similar looking objects, but NASA's Cassini spacecraft recently captured an ‘Earth-selfie' from 890 million miles away.

Why Titan Has No Waves

A new study published in the journal Icarus attempts to answer the question of where all the waves went on Saturn's moon Titan.

MESSENGER To Capture Earth, Moon In Series Of Images This Weekend
2013-07-19 07:10:22

With some inspiration by the Cassini team's plans to image the Earth on July 19, scientists working with NASA's MESSENGER spacecraft orbiting Mercury are preparing to catch the Earth in a series of images taken of natural satellites around the Sun's closest planet.

Smile And Wave At Saturn!

NASA's Cassini spacecraft currently orbiting around Saturn will be poised to snap an image of Earth on Friday, and the space agency is asking the public to photobomb the picture.

Blue Exoplanet Shares Earth Color Only

Using imagery from the Hubble Space Telescope, astronomers have determined that a planet orbiting a star close to our solar system has a deep azure blue color when seen from space, much like Earth.

Cassini Helps Understand Saturn Storms

Scientists reported in the journal Nature Geoscience that images taken by the Cassini space probe helped them understand the nature of the giant storms on Saturn.

Cassini Spacecraft To Take Picture Of Earth From Nearly 900 Million Miles Away
2013-06-19 06:21:51

The jointly operated NASA/ESA/ASI Cassini-Huygens orbiter exploring Saturn is set to take a spectacular image of Earth this afternoon – July 19 – during a solar eclipse of the sixth planet. Earth will actually appear as a small, pale blue dot between the rings of Saturn during the mosaic imaging event.

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...

Gas Giant

Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...

Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...

Uranus -- Uranus is the seventh planet from the sun. It is a gas giant. Physical characteristics Uranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather...

Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
