A look back at this scientific result, released one year after the landing of the InSight probe on Mars, and the start of recordings by SEIS, the French seismometer that measures the activity of the Martian soil. In a series of 6 papers published on Monday 24 February 2020 in Nature Geoscience and Nature Communication, the science team of NASA’s […]

ECLAIRs is the main instrument of the SVOM space mission that will be launched in June 2022. A Franco-Chinese mission developed in partnership with the CNES, the CEA and the CNRS, one of the main subjects of which is the study of gamma-ray bursts. This result looks at the role that ECLAIRs could play in the detection of ultra-long gamma-ray […]

Dune fields, with their periodic patterns visible from space, are one of the most recognizable landscapes on Earth and other planetary bodies. The periodicity of the dunes can be directly associated with the atmospheric conditions in which the dunes develop. By understanding how these dunes form on Earth, scientists could deduce from these mechanisms the environmental parameters that have allowed […]

The APC laboratory is heavily involved in the development of X-IFU, the high-resolution spectrometer for Athena, the future European X-ray space observatory currently scheduled for launch in 2031. The result described here is a further step in the development of the X-IFU readout chain. Powerful sources of X-rays, extreme phenomena such as black holes, galaxy clusters and star explosions, are […]

RETROSPECTIVE. Correctly predicting the strength of an earthquake takes time, with the risk of underestimating the magnitude of the phenomenon. A new technique, based on changes in the gravitational field during an earthquake, seems promising. It could deliver results in just a few minutes, and could save lives. Earthquakes are the only completely unpredictable natural phenomena on earth. Although unpredictable, […]
