R Aquarii (Image ESO/Schmid et al.)

An article published in the journal “Astronomy & Astrophysics” describes a new observation of the R Aquarii binary system, consisting of a red giant of the type called Mira variable and a white dwarf. A team of researchers used that pair of stars as a target for a test of a new subsystem of the SPHERE instrument mounted on ESO’s VLT obtaining the clearest image captured so far of the turbulence existing in the system due to the fact that the white dwarf is stealing gas from its companion, worsening its agony.
