New images and data from ESA’s mission to Venus provide new insights into the turbulent and noxious atmosphere of Earth’s sister planet. What causes violent winds and turbulences? Is the surface topography playing a role in the complex global dynamics of the atmosphere? Venus Express is on the case.

UK researchers from University College London (UCL), along with colleagues from Boston University, have found that the hotter than expected temperature of Saturn's upper atmosphere – and that of the other giant planets – is not due to the same mechanism that heats the atmosphere around the Earth's Northern Lights.

Carbon dioxide emissions from global warming are cooling and shrinking the outermost atmosphere, keeping orbiting spacecraft airborne longer but also increasing the threat that space junk poses to satellites.

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.

This year's Antarctic ozone hole is the biggest ever, government scientists said Thursday. The so-called hole is a region where there is severe depletion of the layer of ozone - a form of oxygen - in the upper atmosphere that protects life on Earth by blocking the sun's ultraviolet rays.

Air from the oldest ice core confirms human activity has increased the greenhouse gas carbon dioxide (CO2) in the atmosphere to levels not seen for hundreds of thousands of years, scientists said on Monday.

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Important things to know when it comes to weather are the terms that a meteorologist uses on the television, radio or on a weather website.  The first term is Return flow. Sometimes you will hear a meteorologist use this term. The best way to understand this is to look at a weather map. When you see a High pressure center which is the blue H, look to the western side of that high pressure. This is where the warm moist air starts moving from the south back towards the north, which is why it...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

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...
