The latest results of the Eros2 experiment are presented. the search for gravitational microlensing events toward the Galactic Center and toward the Magellanic Clouds yielded an optical depth τbulge = 0.94 ± 0.29 × 10–6, and a strong limit, combining all Eros analyses, on the composition of the halo. Less than 25% of a standard halo can be composed of MACHOs with a mass range [10–7, 1] M⊙ at the 95% C.L.
