Latest Planetary atmospheres Stories
NASA’s Curiosity rover has been busy searching for signs that life may have once existed on the Red Planet. In the eight months since NASA dropped the rover on Mars, it has made significant progress in the hunt for water and life.
Scientists reported in the journal Nature Communications that complex organic chemistry could eventually lead to the building blocks of life on Saturn's moon Titan.
We are learning something new about the red planet almost daily. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold.
Uranus is coming into more focus than ever with a new technique developed by astronomers and applied at the Keck Observatory.
The Venus Express spacecraft snapped an image last December showing off clouds on Venus, and how they wrap the planet and its entirety.
The European Space Agency said on Monday that Venus Express has spotted an area of Venus that may be cold enough to produce carbon dioxide snow.
As the fall season starts to ramp up here in the U.S., observations show Saturn's moon Titan has its own drastic seasonal changes.
Bits of "meteor smoke" have been detected in a noctilucent cloud (NLC), supporting an already existing theory.
Titan appears to be strung like a bead on Saturn’s rings, which cast shadows onto the southern hemisphere of the gas giant in this beautiful image from Cassini.
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 -- 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 -- 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...
