Venus may have been a water world, space congress told Paris (AFP) Sept 16, 2009 
Venus is characterised today as the planet from hell yet may have been closer to a cherished idea that it was once Earth's twin, a conference heard on Wednesday. Data sent back by a European scoutship suggests that even though Venus' surface is super-heated and smothered by a lethal atmosphere, the planet may once have been lush with water. The second rock from the Sun is similar in size ... read moreVenus' Atmosphere Observed - SCIAMACHY On Envisat Looks Elsewhere 
Bonn, Germany (SPX) Jul 21, 2009Scientists at the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) and the Netherlands Institute for Space Research (SRON) have found a new area of deployment for the SCIAMACHY (SCanning Imaging Absorption SpectroMeter for Atmospheric CHartographY) atmospheric instrument on the European environmental satellite Envisat. In March and June 2009, the spectrometer, in a ... more

New Map Hints At Venus' Wet, Volcanic Past
Paris, France (ESA) Jul 15, 2009Venus Express has charted the first map of Venus's southern hemisphere at infrared wavelengths. The new map hints that our neighbouring world may once have been more Earth-like, with both, a plate tectonics system and an ocean of water. The map comprises over a thousand individual images, recorded between May 2006 and December 2007. Because Venus is covered in clouds, normal cameras cannot ... more Earth-Venus smash-up possible in 3.5 billion years: study 
Paris (AFP) June 10, 2009A 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 ... more Watching 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 To Fly Closer To Venus
Paris, France (ESA) Jul 16, 2008A series of orbit control manoeuvres is underway to alter the orbit of the Venus Express spacecraft, with the goal of reducing the pericentre altitude to 185 km. These manoeuvres, which began on 13 July, provide new opportunities for scientific observations of regions which have not been probed by the spacecraft so far. In April 2006, Venus Express successfully entered orbit around ... more New Details On Venusian Clouds Revealed 
Paris, France (ESA) Jun 09, 2008As ESA's Venus Express orbits our sister planet, new images of the cloud structure of one of the most enigmatic atmospheres of the Solar System reveal brand-new details. Venus is covered by a thick layer of clouds that extends between 45 and 70 km above the surface. These rapidly-moving clouds are mainly composed of micron-sized droplets of sulphuric acid and other aerosols (fine solid or ... more Venus Express Provides First Detection Of Hydroxyl In Atmosphere Of Venus 
Paris, France (ESA) May 20, 2008The VIRTIS instrument on Venus Express has made the first detection of hydroxyl in the atmosphere of Venus. This provides new insight into the dynamics of the upper atmosphere and the climate system of the planet. The results are published in the May 2008 issue of Astronomy and Astrophysics. Measurements of airglow emission from planets is an important tool in understanding the chemical ... 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 |
