Iowa Planeterrella

The “Iowa Planeterrella” was built at the University of Iowa in 2015-2016. It follows closely the Planeterrella design provided by Dr. Lilensten. Three modifications were made so that it could be incorporated into a museum exhibit. The first is an electronics switchboard that allows users to switch between different configurations by turning a knob (currently these are the radiation belt, aurora and ring current demonstrations). The second is an automated pressure control that maintains the (...)

Hasselt Plenetterrella in Belgium

2015 was the international year of light. Fascinated by this enthralling physical phenomenon, our department wanted to astonish visitors of that year’s Science Day by showing them a few ‘magical’ light experiments and in particular, the mysterious ‘aurora’. All of this on a non-polar latitude, i.e. Belgium.
We had already built a Tesla Coil in the past (of course in miniature), and also found some smaller experiments implicating to the wonderful theory behind light. But we wanted something (...)

A Planeterrella at NASA

Guillaume Gronoff was my former PhD student. Very bright, very nice person, he is now not only a colleague but also a friend. As a PhD student, he was immediately attracted by the Planeterrella and made many demos, including one on and French TV channel. He is now under contract with NASA in the Langley center. It was no surprise to me that he managed to convince his colleagues to make their own Planeterrella. It was completed on August 20th, 2013. A press communiqué was immediately released (...)

At CERN in Geneva

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. They use the world’s largest and most complex scientific instruments to study the basic constituents of matter - the fundamental particles. The particles are made to collide together at close to the speed of light. The process gives the physicists clues about how the particles interact, and provides insights into the fundamental laws of nature. At CERN , (...)

The Planeterrella at Palais de la Découverte in Paris

The Palais de la Découverte in Paris is the largest space dedicated to scientific mediation France. I do not know a single French scientific researcher who, as a child, did not dream there (including me). The Planeterrella is the result of the will of Kamil Fadel, head of the physics department, Fabien Banaji, a great technician, and Brigitte Zana, who signed the contract on behalf of the Palace. It was first shown in April 2015 and gave me a shock: it is even more beautiful than the (...)

The Planeterrella of the Plateau of the Royal Observatory of Belgium in Brussels

The Planeterrella of the Plateau of the Royal Observatory of Belgium in Brussels was completed just in time for the open doors days of the Observatory on 25 and 26 May 2013. A great success, since Eddy Equeter, who built it, presented to the public continuously from 10:00 to 6:30 p.m., as the crowd who wanted to see the aurora was important! This Planeterrella originated from Cyril Simon, who helped design the first Planeterrella when he was a PhD student at the Laboratory of Planetology of (...)

The planeterrella II

The planeterrella II was born in 2011. The growing success of Planeterrella I led to some changes. Indeed, the initial gauge of 30 people is not enough for more than a hundred people coming now alltogeher to Planeterrella exhibitions. Therefore, we added a camera. In the picture, it is a webcam that has not worked well. Since then, the theatre Hexagone de Meylan (http://www.theatre-hexagone.eu/scene-nationale/index.php), through its action "Rencontres I" funded a color CCD camera. We chose (...)

Other agreements have been signed or are in progress.
In France, several planeterrellas are under construction or planned. The most advanced is perhaps that of the University of Orleans, under the direction of Sebastian Celestin. Others seem to max out at the Polytechnic School in Palaiseau (Malik Mansour), the University of Lille (Thomas Paget), at the Planetarium of Capelle la Grande, the PLUS (David Pinte). In the south of France, a dynamic association is creating the "House of the Sun" (...)

Meudon’s planeterrella

The idea to build a Planeterrella at Observatoire de Paris-Meudon (more exactly within the Department of Studies and Instrumentation in Astrophysics (LESIA) located in Meudon) naturally germinated following the presentation of the experience by our eccentric friend Jean Lilensten during the National solar terrestrial meeting at Obernai in March 2008.
Researchers at the pole plasma LESIA, Baptiste Cecconi and Laurent Lamy, soon joined by Carine Briand, understood what a dramatic tool it is (...)

Technical details about Planeterrella
For this experiment, and with the assistance of the SERAS office Study (CNRS), I use a vacuum chamber with a volume of fifty liters. The enclosure is made in Plexiglas, which filters ultraviolet correctly. The base is in aluminum. You can also use copper, more expensive and less convenient. It needs to be a non-ferromagnetic metal. On the inside, I have an electric duct mounted on a wheel, wich I can tilt and move on a gallow. The spheres are mounted (...)
