- MOA-2011-BLG-191 est un trou noir stellaire errant à grande vitesse dans la Voie lactée. Il a été découvert par une équipe de recherche internationale lors de l'étude d'un phénomène de microlentille gravitationnelle faite avec le télescope spatial Hubble. (fr)
- OGLE-2011-BLG-0462, also known as MOA-2011-BLG-191, is a stellar-mass black hole isolated in interstellar space. OGLE-2011-BLG-0462 lies at a distance of 5,000 light years in the direction of the galactic bulge in the constellation Sagittarius. The black hole has a mass between 1.6 and 4.4 M☉, but might weigh as much as 7.1±1.3 M☉ The discovery of OGLE-2011-BLG-0462 makes this object the first truly isolated black hole found. OGLE-2011-BLG-0462 was discovered through microlensing when it passed in front of a background star that was 20,000 light years away from Earth. The black hole's gravity bent the star's light, causing a sharp spike in brightness that was detected by the Hubble Space Telescope. It took six years to confirm the existence of OGLE-2011-BLG-0462.
