Latest Pioneer Venus project Stories
Underscoring the vast differences between Earth and its neighbor Venus, new research shows a glimpse of giant holes in the electrically charged layer of the Venusian atmosphere, called the ionosphere.
After a successful end to a long mission, ESA is allowing Venus Express to rise one last time before ending its life in a fiery crash with Earth's sister planet.
ESA officials explain that Venus’s thick atmosphere contains more than a million times as much sulphur dioxide as Earth’s, and offer that most of the pungent, toxic gas must be generated by volcanic eruptions.
When Venus transits the sun on June 5th and 6th, an armada of spacecraft and ground-based telescopes will be on the lookout for something elusive and, until recently, unexpected: The Arc of Venus.
Venus is a rarity among planets - a world that does not internally generate a magnetic field. Despite the absence of a large protective magnetosphere, the near-Venus environment does exhibit a number of similarities with planets such as Earth.
At first glance, a weather forecaster for Venus would have either a really easy or a really boring job, depending on your point of view.
Japan's space agency said that it had successfully test-fired the engine of its "Akatsuki" space probe.
New analysis of images taken by ESA's Venus Express orbiter has revealed surprising details about the remarkable, shape-shifting collar of clouds that swirls around the planet's South Pole.
Despite the great differences between the atmospheres of Venus and Earth, scientists have discovered that very similar mechanisms produce lightning on the two planets.
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 Pioneer Program is a series of American unmanned space missions designed for planetary exploration. The program included a number of missions, but the most well-known missions were Pioneer 10 and Pioneer 11. Both Pioneer 10 and 11 explored the outer planets and left our solar system. Both probes carry a gold plaque, depicting a man and a woman and information about the origin of the probes and their creators. The Pioneer probe was named by Stephen A. Saliga, who was chief designer of Air...
