The enigma of icy bodies in the Solar System

Researchers from CEA and Paris-Diderot University think they have discovered the phenomenon behind the exceptional thermal insulation of small icy bodies located beyond Jupiter: an underlayer of amorphous ice water, a few centimeters below the surface. They now understand better why these bodies are unable to store heat from the sun. This work is published in the April volume of the journal Astronomy & Astrophysics.

No gamma echo to the merger of two black holes

The INTEGRAL satellite to search for the source of gravitational waves

One instrument of the INTEGRAL satellite that continuously monitors the sky was active at the time of the discovery by the LIGO instrument of the first ever-detected gravitational wave, GW150914, resulting from the merger of two black holes. It allowed to search the existence of a high-energy source of light, associated with this exceptional event.
