[Dark matter really does exist!] Data acquired by the space mission reveals that the speed of stars in our galaxy, the Milky Way, decreases at great distances from the galactic center.

Two IRAP researchers have shown that only a model that includes dark matter can accurately reproduce the observed decrease. Gone is the MOND (MOdified Newtonian Dynamics) theory ...

Time demanding, but also a nice way to explore what's boiling in all open research fields in and know what are the challenges and the mysteries around!
