(Image: CERN)The Etat de Genève and CERN1 are today announcing the imminent start of work just outside the CERN site to create the brand-new Esplanade des Particules, a space worthy of Europe’s leading laboratory for particle physics. At the gateway into Geneva and Switzerland, CERN is already a top visitor attraction and enjoys global renown. The project will integrate the Laboratory better into the local urban landscape, making it more open and more easily accessible. Work will begin on 18 April and will last for a period of 16 months.

The idea for an Esplanade des Particules came jointly from the République et Canton de Genève, CERN and the Commune de Meyrin. A competition was launched in 2011 for a redesign of the Route de Meyrin intended to showcase the public entrance to CERN. The landscape architects Studio Paolo Bürgi of Ticino won this international competition with their design for a large space dedicated to pedestrians and sustainable modes of transport, connecting CERN’s Reception to the Globe of Science and Innovation, a symbol of CERN and of sustainable development, donated to the Organization by the Swiss Confederation.

In 2016, more than 120 000 people from all over the world visited CERN. In order to facilitate access for this ever-growing number of visitors, the Esplanade des Particules will be a public space aimed at sharing CERN’s creative and dynamic atmosphere, with local and international visitors alike.

40% of the project is financed by the Swiss Confederation in the framework of the urban development project and the remaining 60% is split between the Canton de Genève, CERN and the Commune de Meyrin. “As a cross-border international organisation, CERN embodies the spirit of Grand Genève and I’m happy that this project, which is worthy of this emblematic institution, is coming to fruition,” said Mr Luc Barthassat, state councillor in charge of the Department of the Environment, Transport and Agriculture.

“As with the Globe of Science and Innovation, which symbolises our desire to welcome the general public, the Esplanade des Particules will further demonstrate CERN’s openness to the city of Geneva and to the world,” said Dr Fabiola Gianotti, CERN Director-General. “We are looking forward to working with all of our partners to continue to develop the space around the Globe.”

The Esplanade des Particules is a public space comprising several key features:

  • The current Flags Car Park will be replaced by a blue-coloured pedestrianised area that will extend as far as the Globe.
  • A forest of national flags will cross the Route de Meyrin to link CERN’s main site with the Globe, symbolising CERN’s international collaboration.
  • A large number of covered bike racks will be constructed.
  • The Route de Meyrin will continue to serve road traffic but the speed limit will be reduced to 50 km/h at the point where it crosses through the public area.

“We are pleased to be participating in this project, which will increase CERN’s visibility in the local area,” said Mr Pierre Alain Tschudi, administrative councillor for the Commune de Meyrin. “This work is fully in line with Meyrin’s desire to create attractive and pleasant public spaces to help us all to live together in harmony.”

Impacts of the work on transport:

  • The Route de Meyrin will remain open.
  • Public transport (bus Y and tram 18) will continue to operate.
  • CERN’s entrances will remain accessible.

Volcanes jóvenes en la Luna

En el año 1971, los astronautas de la nave espacial Apollo 15, en la órbita de la Luna, fotografiaron algo muy extraño. Los investigadores lo llamaron “Ina”, y parecía ser lo que quedó después de una erupción volcánica.

No hay nada extraño respecto de los volcanes en la Luna, per se. Gran parte de la antigua superficie de la Luna está cubierta por lava endurecida. Las principales características del “Hombre en la Luna”, de hecho, son viejos flujos basálticos depositados hace miles de millones de años cuando la Luna fue devastada por violentas erupciones. Lo extraño respecto de Ina era su edad.

Durante mucho tiempo, los científicos planetarios han pensado que el vulcanismo lunar llegó a su fin hace alrededor de mil millones de años, y poco ha cambiado desde entonces. Sin embargo, Ina se veía notablemente nuevo. Durante más de 30 años, Ina siguió siendo un misterio, una rareza “única” que nadie podía explicar.

Revolucionarias imágenes de ALMA revelan una génesis planetaria

Esta es la imagen más nítida jamás obtenida por ALMA — más precisa que las que se toman rutinariamente en luz visible con el telescopio espacial Hubble de NASA/ESA. En ella vemos el disco protoplanetario que rodea a la joven estrella HL Tauri. Estas nuevas observaciones de ALMA revelan subestructuras dentro del disco que nunca antes se habían visto, e incluso muestran las posibles posiciones de los planetas formándose en las manchas oscuras dentro del sistema.

Esta nueva imagen de ALMA, el Atacama Large Millimeter/submillimeter Array, revela detalles extraordinarios que nunca antes se habían visto en un disco de formación de planetas alrededor de una estrella joven. Estas son las primeras observaciones que ha utilizado ALMA en su configuración casi completa, y las imágenes más precisas hechas nunca en longitudes de onda submilimétricas. Los nuevos resultados son un enorme paso adelante en la observación de cómo se desarrollan los discos protoplanetarios y cómo se forman los planetas.

Para sacar el máximo partido de ALMA en su nueva y potente configuración, los investigadores decidieron apuntar las antenas hacia HL Tauri— una estrella joven rodeada por un disco de polvo [1] y situada a unos 450 años luz de distancia. La imagen resultante supera todas las expectativas y revela finos detalles inesperados en el disco de material sobrante tras el nacimiento de la estrella. La imagen muestra una serie de anillos concéntricos brillantes, separados por huecos [2].

ESOcast 69 presents the result of the latest ALMA observations, which reveal extraordinarily fine detail that has never been seen before in the planet-forming disc around the young star HL Tauri.

This revolutionary image is the result of the first observations that have used ALMA with its antennas at close to the widest configuration possible. As a result, it is the sharpest picture ever made at submillimetre wavelengths.

“Lo que hemos observado es, casi con total seguridad, el resultado de la formación de cuerpos planetarios jóvenes en el disco. Esto resulta sorprendente, ya que no se espera que estrellas jóvenes de este tipo tengan grandes cuerpos planetarios capaces de producir las estructuras que vemos en las imágenes”, afirma Stuartt Corder, Subdirector de ALMA.
