Summary: even the most powerful high tech telescopes are barely able to record remote low-mass and thus faint stars. together with researchers from poland and chile, an astrophysicist from the university of zurich has now detected a low-mass star in globular cluster M22 for the first time through microlensing. the result indicates that the overall mass of globular clusters might well be explained without enigmatic dark matter.
Critique: it was pretty interesting.
