As the end of its eight-year adventure at Venus edges ever closer, ESA scientists have been taking a calculated risk with the Venus Express spacecraft in order to carry out unique observations of the planet's rarefied outer atmosphere. First results from this aerobraking campaign were reported today at the 2014 meeting of the American Astronomical Society's Division for Planetary Sciences in Tucson, Arizona.

Venus is hiding something beneath its brilliant shroud of clouds: a first order mystery about the planet that researchers may be a little closer to solving because of a new re-analysis of twenty-year-old spacecraft data.

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.

The atmospheric waves of Venus, key to understanding the superrotation of its atmosphere, have been deciphered. Venus' atmosphere rotates up to sixty times faster than its surface, a phenomenon known as superrotation whose origin has yet to be satisfactorily explained.

After eight years in orbit, ESA's Venus Express has completed routine science observations and is preparing for a daring plunge into the planet's hostile atmosphere.

Rainbow-Like Feature on Venus

A rainbow-like feature known as a 'glory' has been seen by ESA's Venus Express orbiter in the atmosphere of our nearest neighbour - the first time one has been fully imaged on another planet.

Space Weather Explosions at Venus

Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus.

NASA has released a natural-color image of Saturn from space, the first in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible.

Venus As Seen From Saturn by Cassini

Peering over the shoulder of giant Saturn, through its rings, and across interplanetary space, NASA's Cassini spacecraft spies the bright, cloudy terrestrial planet, Venus. The vast distance from Saturn means that Venus only shows up as a white dot, just above and to the right of the image center.

When a Planet Behaves Like a Comet

ESA's Venus Express has made unique observations of Venus during a period of reduced solar wind pressure, discovering that the planet's ionosphere balloons out like a comet's tail on its nightside.

This graphic shows the path of Venus across the face of the sun on Dec. 21, 2012, as will be seen by NASA's Cassini spacecraft in the Saturn system. This will be the first time a spacecraft has tracked a transit of a planet in our solar system from beyond Earth orbit.

Six years of observations by ESA's Venus Express have shown large changes in the sulphur dioxide content of the planet's atmosphere, and one intriguing possible explanation is volcanic eruptions.

Chasing clouds on Venus

Clouds regularly punctuate Earth's blue sky, but on Venus the clouds never part, for the planet is wrapped entirely in a 20 km-thick veil of carbon dioxide and sulphuric dioxide haze. This view shows the cloud tops of Venus as seen in ultraviolet light by the Venus Express spacecraft on 8 December 2011, from a distance of about 30 000 km.

The September 2012 edition of Space Quarterly Magazine is now available. Here are the table of contents for the U.S. and Canadian editions.

Venus: An Engineering Problem

Hot, toxic, and murky, Venus serves as an extraordinary engineering challenge, according to Jim Garvin. Venus is bizarre. One day on Venus is nearly as long as one year on Earth. It rotates about its axis in the opposite direction of all the other planets in our solar system.

On Tuesday, 5 June 2012, Venus will cross the face of the sun - as seen from Earth beginning at 22:09 UT (6:09 PM EDT). These transits are rare - they occur in pairs and only very century or so. The last transit was in 2004. The next one will be in 2117. Below are a series of links to various resources you can use to best appreciate this once in a lifetime experience.

A Venus transit across the face of the Sun is a relatively rare event -- occurring in pairs with more than a century separating each pair. There have been all of 53 transits of Venus across the Sun between 2000 B.C. and the last one in 2004.

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.
