The Cosmic Jellyfish in Norma seen by ALMA
A galaxy may have all its gas swept out by ram-pressure when entering a galaxy cluster at high velocity. The result looks like a jelly-fish, where the head...
Radio emission from a pulsar’s magnetic pole revealed by general relativity
Using data from the Arecibo and Nançay radio telescopes collected over the past 14 years, a scientific team led by a researcher at the Paris Observatory was...
Supersonic winds in Titan’s upper atmosphere
An international team led by researchers from the LESIA obtained the first direct measurement of the wind speed in the upper atmosphere of Titan using the...
The echo of the stellar bar formation in our Galaxy captured by Gaia
New numerical simulations of the bar formation in the Milky Way, carried out by astronomers of Paris Observatory, show that it is possible to explain the...
A New Cosmological Ruler to track Dark Energy
To determine the characterisrtics of our Universe, and in particular the nature of the Dark Energy corresponding to 70% of its content, we must measure the...
Does quantum entanglement influence the universality of free fall?
Remi Geiger (Paris Observatory) and Michael Trupke (Vienna University) have proposed a conceptually new way of testing the foundational principle of General...
CTA Releases its Updated Science Case
September 24th, 2017 — The Cherenkov Telescope Array (CTA) will be the foremost global observatory for very high-energy gamma-ray astronomy over the next...
Large reservoirs of cold molecular gas at high-redshift
August 24th, 2017 — Galaxies in the early time had not yet formed a lot of stars, but were essentially made of gas. This gas can now be observed with ALMA...
Radio shows from Jupiter seen by Juno
Le 26 mai 2017 est paru un numéro spécial de la revue « Geophysical Research Letters » rassemblant plus d’une quarantaine d’articles portant sur l’analyse...
The Stellar Seismic Indices (SSI) data base
The oscillation spectra obtained by the CoRoT and Kepler space missions have enabled the detection of solar-type oscillations in a large number of red giant...
