The paradox of solar polarization finally resolved by a French theory
The paradox of the polarization of the sodium line from the Sun, which dated from 1997, has been resolved. The paradox arose from an observation by Stenflo...
Cosmological parameters from measurements of the sparsity of galaxy clusters
A team of astrophysicists from the Paris Observatory and INAF-Bologna has performed an estimation of the cosmological parameters using a new method based on...
CHEOPS finds unique planetary system tuned in a chain of Laplace resonances
The CHEOPS space telescope detects six planets orbiting the star TOI-178. Five of the planets are trapped in an exceptional chain of Laplace resonances in...
Phosphine on Venus : No detected traces in infrared spectra
An international team, coordinated by researchers from Paris Observatory - PSL, at LESIA, has searched for the signature of PH3 on Venus in infrared spectra....
First results of CHEOPS on an extreme exoplanet
The CHEOPS Space Telescope keeps its promises: Its first observations reveal the face of the exoplanet WASP-189b - one of the most extreme planets known....
Discovery of an extrasolar system with two strongly interacting planets
An international team led by Guillaume Hébrard, researcher at Institut d’astrophysique de Paris, and involving researchers from Paris Observatory has...
General relativity confirmed using Nançay’s radiotelescope
A collaboration involving researchers from Paris Observatory - PSL, CNRS and LPC2E (Orléans) reports in the journal Astronomy and Astrophysics the most...
The surface of the Sun is magnetized
A recent compilation of several spectroscopic observations of the surface of the Sun shows that the magnetic field gradient in the vertical direction is 3...
MICADO, future ELT camera, takes an important step in its design
C’est officiel depuis le 21 janvier 2020. MICADO, instrument de première lumière de l’Extremely Large Telescope (ELT) de l’ESO, franchit avec succès sa revue...
A new constraint on the mass of "graviton"
Scientists from the observatories of Paris and Côte d’Azur, as well as the scientific center of Monaco, have used solar system data in order to constrain the...
