The main activity at Nançay is the development and application of new radio techniques to fundamental research in astrophysics and astronomy. A number of instruments are operated on behalf of researchers in France and worldwide to conduct scientific programmes of observation of the Universe, including the nearby Earth-Space environment, the study of the Sun and the solar system, and the study of distant stars and galaxies in the Universe.

Planetary Data System
Description:
Vector magnetic field data acquired by the Fluxgate Magnetometer
instrument aboard the MAVEN spacecraft. The data are calibrated and
provided in physical units (nT). The time resolution depends on the
telemetry rate available when the data were taken. The data are
expressed in Payload coordinates.

Since 1973, the 18-cm lines of the OH radical have been
systematically observed in a number of comets with the Nançay radio
telescope. This allowed an evaluation of the cometary water production
rates and their evolution with time, as well as a study of several
physical processes: the excitation mechanisms of the OH radio lines,
the expansion of the cometary atmospheres, their anisotropy in
relation with non-gravitational forces, the Zeeman effect in relation
with the cometary magnetic field. The Nançay observations of 53
cometary apparitions between 1982 and 2009 are now organized in this
database.
The NASA/IPAC Extragalactic Database (NED) provides a comprehensive fusion
of multi-wavelength data for hundreds of millions of objects located beyond
the Milky Way galaxy. As new observations are published in NASA mission
archives, journal articles and sky survey catalogs, they are cross-identified
with prior measurements and integrated in a unified database. Numerous derived
quantities are also provided to facilitate scientific research. For more
