Scientists controlling space-based analysis instruments aimed at the Earth have known for a long time that the outlines of the Earth's continents can easily be distinguished from orbit from the outlines that they project onto clouds. This may be owed to the significant differences that appear between cloud cover... |

An international collaboration of architects, engineers and artists has recently released its plans for the new “digital cloud” that will adorn London's skyline pretty soon. The giant, inflatable structures would essentially float on its support pillars, and would be used primarily for displaying mul... |

No one is surprised when lightning comes down form the sky, especially during one of those intense summer thunderstorms. But witnessing a bolt of light and electricity going upwards, until it almost reaches the upper limit of the atmosphere, is completely another story. One such formation was recently observed by exp... |

Planetary scientists have known for a long time that several billion tons of water disappear from Earth's atmosphere each year, as if by magic. However, despite having this knowledge, explaining why this happens has turned out to be a very tricky question. Now, Technical University of Denmark (DTU) National Spac... |

In the decades since global warming started being acknowledged as a harsh reality, researchers and climatologists have often wondered how the clouds will influence the global rise in temperatures. Increasingly large amounts of greenhouse gases (GHG) can have two effects in the atmospheric formations – they can ... |

Whenever people think of the Red Planet, what usually jumps to mind are the arid, barren and sandy landscapes that have been widely circulated over the years in NASA images. But the reality of the Martian surface is a bit different than widely believed, a fact that was evidenced by the last readings sent back by the ... |

The scientific theory that holds that bacteria in clouds may be, to some extent, responsible for rain formation has drawn immense criticism from the scientific community when it first appeared, a good 25 years ago. Ever since, a small number of researchers have continued their investigations into this belief, and the... |

An international cooperation between researchers from the United States, Switzerland and Germany has recently proven that lead coming from human activities is able to drastically influence the formation of clouds. The way it does that is by altering the manner in which ice crystals – the main trigger of clouds ... |

Since the beginning of time, mankind has noticed that skies somehow appear to be a lot brighter on portions around clouds, even much more so than perfectly clear skies elsewhere. Thus far, climatologists and planetary scientists have been unable to say exactly why this is happening, but now they believe that the phen... |

Over the last decades, our solar system has been experiencing a massive sand storm, not unlike those that can be found in the desert. All the planets orbited the Sun in a halo of sand particles that is now considerably larger than it was a century ago. The reason for these large amounts of cosmic debris has kept astr... |

Venus' atmosphere is probably the most mysterious of all celestial bodies in the Solar System, presenting an intricate cloud structure which extends between 45 and 70 kilometers above the scorching hot surface. They contain high concentrations of sulphuric acid combined with other aerosols moving at fast speeds,... |

In March 2007 Jupiter spawned a new gigantic atmospheric storm measuring an area of the size of two Earth continents. However, the thick Jovian atmosphere makes the observation of processes which take place inside it very difficult, disabling a good understanding of meteorological phenomenons which trigger these stor... |

Most of the popular science articles and documentaries published over the years imprinted in our imagination a picture of Mars dominated by a massive desert of red sand constantly bayed in sunlight. Recent findings, however, tell a different story. ESA's Mars Express spacecraft revealed the presence of clouds of... |

A strange megacryometeor fell through the roof of a house in Dubuque, Iowa, starting scientific dispute over its origins. Although some phenomena are known to cause this type of large ice meteorite, so far no valid explanation has been found.Megacryometeors are large chunks of ice (mega = very big, cryo = ice), whic... |

For many years, Venus, the second planet from the Sun and the brightest object in the night sky, refused to let astronomers peak under its opaque layer of highly reflective clouds of sulfuric acid, preventing its surface from being seen from space in visible light.Recent pictures taken by two missions designed to st... |

Noctilucent clouds, meaning "night shining" are getting bigger and brighter and that's why NASA is trying to find if they're a sign of global warming or unrelated appearances in the night sky in the northern hemisphere.First observed in 1885, two years after the Krakatoa eruption, the clouds are usually on... |

Breaking images taken by a new NASA satellite shows extremely detailed images of a mysterious kind of clouds appearing over the Arctic region and moving towards Northern Europe. These clouds shine in the night sky and are moving out of the polar regions and scientists can't explain why.They are called "noctiluc... |

A new NASA mission planned for, with an assist from Utah State University, will send a satellite into orbit to study what are known as noctilucent clouds (night shining, in Latin), which appear to glow at night. Forming at the edge of space, they appear to be getting brighter and more frequent, raising questions as ... |
