New Map Hints At Venus' Wet, Volcanic Past
Paris, France (ESA) Jul 15, 2009
Venus 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 ... read more

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 ... more

  • Watching Venus Glow In The Dark
    Paris, France (ESA) Feb 25, 2009
    ESA'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, 2008
    A 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, 2008
    Scientists 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, 2008
    It 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

    Venus Express Provides First Detection Of Hydroxyl In Atmosphere Of Venus
    Paris, France (ESA) May 20, 2008
    The 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, 2008
    Venus 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, 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 ... more

    The Puzzling Eye Of A Hurricane On Venus
    Paris, France (ESA) Mar 14, 2008
    Venus 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
