In a world first, the sounds of Mars and Venus are revealed as part of a planetarium show in Hampshire this Easter.

Despite many years of space exploration, we have no evidence of the sound of other planets. While most planetary probes have focused on imaging with cameras and radar and a couple have carried microphones, none of them successfully listened to the sound of another world.

Now, a team from the University of Southampton, led by Professor Tim Leighton, has the answer. Using the tools and techniques of physics and mathematics, they created the natural sounds of other worlds, from lightning on Venus to whirlwinds on Mars and ice volcanoes on Saturn’s moon, Titan. In addition to these natural sounds, they have modelled the effects of different atmospheres, pressures and temperatures on the human voice on Mars, Venus and Titan (Saturn’s largest moon). They have developed unique software to transform the sound of a voice on earth to one that’s literally ‘out of this world’.

Slooh Space Camera will broadcast a free, real-time feed of the most famous star cluster in the heavens, the Pleiades, meeting up with our nearest and brightest planetary neighbor, Venus. Slooh’s coverage will begin on Tuesday, April 3rd starting at 1:30 PM PDT / 4:30 PM EDT / 20:30 UT. Slooh will provide an observatory feed from our world class observatory site in Canary Islands off the coast of Africa. The broadcast can be accessed at Slooh’s homepage or by visiting Slooh’s G+ page, where you will be able to see the panel interact live via G+ Hangouts On Air.

The Pleiades, otherwise known as the Seven Sisters, is a beautiful bright blue open star cluster 440 light years from Earth. The relative tightness of the cluster is indicative of its young age as the member stars were formed some 100 million years ago and will probably travel together through space as a bound cluster for another 250 million years before the gravity of the Milky Way breaks up the cluster into individual field stars. The central core radius of the cluster is only about 4.5 light years but the remote outer regions of the cluster may extend out as far as 52 light years from the center. The brighter members of the cluster, which make up the Seven Sisters, are blue stars with surface temperatures of about 20,000 degrees which is four times hotter than our own Sun.

Venus is sometimes called the Earth’s sister planet because they are so close in size. However, Venus is very different in many ways, with an atmosphere almost 100 times thicker than Earth’s composed of sulfuric acid and carbon dioxide. Even though it is only slightly closer to the Sun, the surface of Venus averages 900 degrees making it the hottest place in the solar system outside the Sun itself.

While Venus and Pleiades are hundreds of light years apart, they will appear together as neighbors in the same field of view. Venus will pass just below the bright blue star cluster. This incredible event happens only once every eight years.

This is a post I wrote a few weeks back when my son and I were looking at Venus, Jupiter and the Moon.

Venus and Jupiter were approaching their conjunction, which happened about a week ago.
