Does dark energy come from quantum vacuum?
French researchers, including IRAP Toulouse, offer a possible physical origin of dark energy: the gravitational action of the quantum vacuum in an extra dimension of space.
The TAROT telescope recorded the explosion of a star located at 13.4 billion of light years
By acting as a lighthouse, this gamma-ray burst tells us about this early and partly unknown stage of the Universe ...
GOCE : A seismometer in orbit around the Earth
Most people think that seismometers are ground-based instruments, but today earthquakes can also be detected by satellites. Researchers of the Institut de Recherche en Astrophysique et Planétologie (IRAP-OMP, UPS, CNRS) in collaboration with the CNES, the IPGP and the University of Delft, demonstrated it using data from the GOCE mission (Gravity and Ocean Circulation Explorer) of the Europea...
Highlighting the rapid and consistent particle acceleration radiation belts during magnetic storms
An international team made up of IRAP researchers has demonstrated the existence of an acceleration of electrons and protons of the radiation belts of the Earth by Ultra Low Frequency waves
The swan song of super-massive stars lasts several hours
An international team including IRAP researchers has recently discovered that very massive stars could explode following an original way.
