The map comprises over a thousand individual images, recorded between May 2006 and December 2007. Because Venus is covered in clouds, normal cameras cannot see the surface, but Venus Express used a pa...
Earth Sciences |The spacecraft's magnetometer instrument (MAG) detected the unmistakable signature of hydrogen gas being stripped from the day-side. “This is a process that was believed to be happening at Venus ...
Physics and Astronomy |Using the spacecraft’s ultraviolet and infrared cameras, the Venus Express team, including UK scientists, have been able to compare what the planet looks like at different wavelengths, allowing them t...
Physics and Astronomy |Using Venus Express, it is possible to compare what the planet looks like in different wavelengths, giving scientists a powerful tool to study the physical conditions and dynamics of the planet’s atmo...
Physics and Astronomy |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 atmos...
Physics and Astronomy |The OH “radical” is a very special and reactive molecule, which is unusual in conventional chemistry because of its reactivity. Using the VIRTIS instrument onboard Venus Express, an international team...
Physics and Astronomy |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 surface...
Physics and Astronomy |"We are looking for Earth-like planets in the habitable zone of their star, a band not too hot nor too cold for life to exist," says Darren M. Williams, associate professor of physics and as...
Physics and Astronomy |The search for volcanoes is a long-running thread in the exploration of Venus. “Volcanoes are a key part of a climate system,” says Fred Taylor, a Venus Express Interdisciplinary Scientist from Oxford...
Physics and Astronomy |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. There is a similar structure on the planet’s north pole, which was observed ...
Physics and Astronomy |Scientists call this work comparative planetology. Mars Express and Venus Express are so good at it because they carry very similar science instruments. In the case of the Analyser of Space Plasmas an...
Physics and Astronomy |The Venus Express space mission was launched in November 2005 and entered in planetary orbit in April 2006. Since then it has been regularly sending data and images from Venus. Thanks to this space mi...
Physics and Astronomy |The technique is known as stellar occultation. Jean-Loup Bertaux, Service d'Aeronomie du CNRS, France was the first to suggest its use on an ESA mission. It works by watching stars from space, wh...
Physics and Astronomy |The discovery is being announced today at the annual meeting of the American Astronomical Society’s Division of Planetary Sciences in Orlando, Florida. Its presence could affect the way the greenhouse...
Physics and Astronomy |In December 2006, a series of solar flares produced in a single active region were observed from three different points, each approximately 120 degrees apart. The results of these observations are now...
