Venus Express Reboots The Search For Active Volcanoes On Venus Paris, France (ESA) Apr 07, 2008 
ESA'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 ... read 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 Venus Express Seeks Out Gases Below The Clouds 
Paris, France (ESA) Feb 20, 2008ESA's Venus Express has recently 'peeled back' the thick clouds around Venus to provide the most accurate and wide-ranging map of water vapour and other gases in the lower atmosphere to date. As a planet, Venus does not radiate a significant amount of visible light. But because of the searing temperatures below its thick cloud layer, reaching 200degreesC at an altitude of 35 km and more the ... more VIRTIS Observations Of Venusian Lower Atmosphere 
Paris, France (ESA) Feb 05, 2008Since the successful orbit insertion of Venus Express in April 2006, the VIRTIS instrument has gathered numerous high-resolution spectra of Venus' atmosphere in the wavelength range 2-5 micron. Taking advantage of a broad spectral window around 2.3 micron, the data has allowed for mapping of minor constituents in the deep atmosphere below the planet's thick cloud deck. VIRTIS, the Visible ... more The Restless Atmosphere Of Venus 
Paris, France (ESA) Dec 05, 2007Venus Express has studied the true extent of Venus's restless atmosphere. This includes the planet's glow, its highly variable south polar vortex and the dynamic upper atmosphere, different from what is seen on any other rocky planet of the Solar System. Venus' faint glow of light coming from molecules in the atmosphere is providing scientists a detailed look into its physical and chemical proce ... more |

Moffett Field CA (SPX) Dec 03, 2007ESA's Venus Express has revealed Venus as never before. For the first time, scientists are able to investigate from the top of its atmosphere, down nearly to the surface. They have shown it to be a planet of surprises that may once have been more Earth-like, and still is, to a certain extent. Scientists hope that by studying atmosphere and climate of Venus, we may be able to better understand ph ... more Venus: Earth's Twin Planet
Paris, France (ESA) Nov 29, 2007ESA's Venus Express has revealed Venus as never before. For the first time, scientists are able to investigate from the top of its atmosphere, down nearly to the surface. They have shown it to be a planet of surprises that may once have been more Earth-like, and still is, to a certain extent. The latest results from the mission were presented today at a press conference held at ESA headquarters ... more Venus inferno due to 'runaway greenhouse effect', say scientists 
Paris (AFP) Nov 28, 2007Once styled as Earth's twin, Venus was transformed from a haven for water to a fiery hell by an unstoppable greenhouse effect, according to an investigation by the first space probe to visit our closest neighbour in more than a decade. Like peas in a cosmic pod, the second and third rocks from the Sun came into being 4.5 billion years ago with nearly the same radius, mass, density and chemic ... more NASA Scientist Confirms Light Show On Venus 
Paris, France (ESA) Nov 29, 2007Venus is a hellish place of high temperatures and crushing air pressure. The European Space Agency's Venus Express mission adds into this mix the first confirmation that the Venusian atmosphere generates its own lightning. The discovery is part of the Venus Express science findings that appear in a special section of the Nov. 29 issue of the journal Nature. "In addition to all the pressure ... more New Isotope Molecule May Add To Venus' Greenhouse Effect 
Paris, France (SPX) Oct 11, 2007Planetary scientists on both sides of the Atlantic have tracked down a rare molecule in the atmospheres of both Mars and Venus. The molecule, an exotic form of carbon dioxide, could affect the way the greenhouse mechanism works on Venus. The discovery is being announced today at the annual meeting of the American Astronomical Society's Division of Planetary Sciences in Orlando, Florida. Its pres ... more |

Laurel MD (SPX) Jun 15, 2007The Messenger spacecraft snapped a series of images as it approached Venus on June 5. The planet is enshrouded by a global layer of clouds that obscures its surface to the Messenger Dual Imaging System (MDIS) cameras. This single frame is part of a color sequence taken to help the Messenger team calibrate the camera in preparation for the spacecraft's first flyby of Mercury on January 14, ... more Venus Express And MESSENGER To Look At Venus In Tandem 
Paris, France (ESA) Jun 05, 2007On 6 June this year, scientists all around the world will be watching with eager eyes as not one but two spacecraft observe Venus simultaneously. ESA's Venus Express, in orbit around Venus since 11 April 2006, will be joined for a few hours by NASA's MESSENGER (MErcury Surface Space ENvironment GEochemistry and Ranging mission), flying by Venus while on its way to Mercury. ... more Ground-Based Observatories Join Forces With Venus Express 
Paris, France (ESA) May 24, 2007Paris, France (ESA) May 24, 2007 Data from Venus Express, which has been revealing new and crucial details about our closest planetary neighbour, will now be augmented by synoptic data from a coordinated ground-based observation campaign. This campaign will contribute to the growing body of information on the nature of Venus's atmosphere and will help put the spacecraft's observations into a ... more Venus Express' Infrared Camera Goes Filming 
Paris, France (SPX) May 08, 2007An exciting new series of videos from ESA's Venus Express has been capturing atmospheric details of day and night areas simultaneously, at different altitudes. The south pole of the planet and its gigantic double vortex has been pictured as never before. The south pole of Venus and the double-eyed storm permanently rule atmospheric phenomena in that area of the planet. They are key to unde ... more One Year At Venus Makes For Some Express Science
Paris, France (ESA) Apr 12, 2007One year has passed since 11 April 2006, when Venus Express, Europe's first mission to Venus and the only spacecraft now in orbit around the planet, reached its destination. Since then, this advanced probe, born to explore one of the most mysterious planetary bodies in the Solar System, has been revealing planetary details never caught before. Intensively visited by several Russian and Ame ... more
