NOEMA a new telescope to explore the invisible universe


NOEMA, the successor to the Plateau du Bure observatory, will be the most powerful millimeter radiotelescope of the Northern Hemisphere:

  • twelve 15-meter antennas on a 2550-meter-high plateau in the French Alps
  • 2000 meters of track on which the antennas can be moved into different configurations
  • 48 high technology reception systems with sensitivities close to quantum limit
  • state-of-the-art electronic equipment designed to process the celestial data

NOEMA will be able to answer some of the most fundamental questions of modern astronomy:

  • see the formation of the first galaxies in the universe
  • understand the role of super-giant black holes at the center of galaxies
  • probe the dynamics and the chemical evolution of nearby galaxies
  • detect complex organic molecules while searching for the key elements of life
  • follow the various stages of stellar formation to the appearance of planetary systems

NOEMA, one of the largest observatories in Europe, will:

  • serve an international community of astronomers
  • undertake hundreds of scientific research projects per year
  • operate in synergy with the largest astronomical instruments on the ground and in space such as ALMA (the most powerful telescope of the Southern Hemisphere) and the James Webb Space Telescope, successor to the Hubble Space Telescope
  • allow testing and implementing new technologies that will push the limits of the exploration of our universe


NOEMA in numbers:




During observations NOEMA's 12 antennas will function as a single telescope, a technique called interferometry. With the antennas pointing towards the same cosmic source, the signals received by each of them are subsequently combined. This method will give NOEMA a resolution of a 1600 meter telescope, equivalent to the distance between its outermost antennas.
