Earth-Venus smash-up possible in 3.5 billion years: study Paris (AFP) June 10, 2009 
A force known as orbital chaos may cause our Solar System to go haywire, leading to possible collision between Earth and Venus or Mars, according to a study released Wednesday. The good news is that the likelihood of such a smash-up is small, around one-in-2500. And even if the planets did careen into one another, it would not happen before another 3.5 billion years. Indeed, there ... read moreWatching Venus Glow In The Dark 
Paris, France (ESA) Feb 25, 2009ESA's Venus Express spacecraft has observed an eerie glow in the night-time atmosphere of Venus. This infrared light comes from nitric oxide and is showing scientists that the atmosphere of Earth's nearest neighbour is a temperamental place of high winds and turbulence. Unfortunately, the glow on Venus cannot be seen with the naked eye because it occurs at the invisible wavelengths of infr ... more

Venus Comes To Life At Wavelengths Invisible To Human Eyes
Paris, France (ESA) Dec 04, 2008A pale yellow dot to the human eye, Earth's twin planet comes to life in the ultraviolet and the infrared. New images taken by instruments on board ESA's Venus Express provide insight into the turbulent atmosphere of our neighbouring planet. Using Venus Express, it is possible to compare what the planet looks like in different wavelengths, giving scientists a powerful tool to study the phy ... more Venus Express Searching For Life On Earth 
Paris, France (ESA) Oct 13, 2008Scientists using ESA's Venus Express are trying to observe whether Earth is habitable. Silly, you might think, when we know that Earth is richly stocked with life. In fact, far from being a pointless exercise, Venus Express is paving the way for an exciting new era in astronomy. Venus Express took its first image of Earth with its Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) ... more How Windy Is It On Venus 
Paris, France (ESA) Sep 19, 2008It is well known that winds on Venus are extremely fast and powerful. Now, ESA's Venus Express has, for the first time, put together a 3-D picture of the venusian winds for an entire planetary hemisphere. The most powerful atmospheric investigator ever sent to Venus, Venus Express has an advantageous orbit around the planet and a unique set of instruments. The spacecraft has the ability to ... more Measuring The Winds Of Venus 
San Sebastian, Spain (SPX) Sep 04, 2008Venus is a planet similar in size to the Earth. Nevertheless, it is quite different in other aspects. On the one hand, it spins very slowly on its axis, taking 224 terrestrial days and, moreover, it does so in the opposite direction to that of our planet, i.e. from East to West. Its dense atmosphere of carbon dioxide with surface pressures 90 times that of Earth (equivalent to what we find ... more |

Key Molecule Found In Venus Atmosphere
Paris, France (ESA) May 16, 2008Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus's dense atmosphere. Hydroxyl, an important but difficult-to-detect molecule, is made up of a hydrogen and oxygen atom each. It has been found in the upper reaches of the Venusian atmosphere, some 100 km above the ... more Venus Express Reboots The Search For Active Volcanoes On Venus 
Paris, France (ESA) Apr 07, 2008ESA's Venus Express has measured a highly variable quantity of the volcanic gas sulphur dioxide in the atmosphere of Venus. Scientists must now decide whether this is evidence for active volcanoes on Venus, or linked to a hitherto unknown mechanism affecting the upper atmosphere. The search for volcanoes is a long-running thread in the exploration of Venus. "Volcanoes are a key part of a ... more The Puzzling Eye Of A Hurricane On Venus 
Paris, France (ESA) Mar 14, 2008Venus Express has constantly been observing the south pole of Venus and has found it to be surprisingly fickle. An enormous structure with a central part that looks like the eye of a hurricane, morphs and changes shape within a matter of days, leaving scientists puzzled. The eye of the hurricane is at the centre of a 2000 km-wide vortex. It was discovered in 1974 by the Mariner 10 spacecraft ... more The Light And Dark Of Venus 
Paris, France (SPX) Feb 22, 2008Venus Express has revealed a planet of extraordinarily changeable and extremely large-scale weather. Bright hazes appear in a matter of days, reaching from the south pole to the low southern latitudes and disappearing just as quickly. Such 'global weather', unlike anything on Earth, has given scientists a new mystery to solve. The cloud-covered world of Venus is all but a featureless, unch ... more |
