Cassini's spectacular image of Saturn's polar vortex, published this month by NASA, may provide astronomers with a missing piece in the puzzle of how that planet's atmosphere works. For planetary scientists studying Venus, the image was strangely familiar.

A recent photo from the Cassini spacecraft shows the mighty planet Saturn, and if you look very closely between its wing-like rings, a faint pinprick of light. That tiny dot is Earth bustling with life as we know it.

A researcher has been studying the practicality of deploying a space sunshade in a global warming crisis; a crisis where it becomes clear that Earth is unmistakably headed for disastrous climate change within a decade or two.

Scientists studying the atmosphere of Saturn's moon, Titan, hope their research will reveal clues about the nature of Earth's atmosphere billions of years ago.

A study of Pluto’s bright frosts suggests that the way the planet cools down is rapid and disorganised. The results were presented at the European Planetary Science Congress in Berlin.

Weather on Earth has a surprising connection to space weather occurring high in the electrically-charged upper atmosphere, known as the ionosphere, according to new results from NASA satellites.

The cloud of oxygen the Cassini spacecraft encountered as it first approached Saturn turned out to be a calling card from another celestial presence, the tiny moon Enceladus.

Mercury is boiling. Mars is freezing. The Earth is just right. When it comes to the temperatures of the planets, it makes sense that they should get colder the farther away they are from the Sun. But then there is Pluto.

Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice. Surface images even show gravel-sized pieces of water ice that resemble rounded stones lying in a dry riverbed on Earth.

Earth's Atmosphere

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

Sky

Sky -- Although almost everyone have seen it, sky is hard to be defined precisely. Generally, sky is the space seen when one looks upward from the surface of a planet. Some people define sky as the denser gaseous zone of a planet's atmosphere. Clouds, rainbows and weather all occur amongst a planet's sky. In astronomy, the sky is divided into many regions, called constellations. The blue colour of the daytime sky results from the selective scattering of light rays. When the sunlight...

Saturn's Moon Titan
2004-10-19 04:45:41

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
