Published for Gaia Data Release 3 on 13 June 2022.
This animation shows a map of the Galaxy with its prominent Galactic Plane and the Bulge. The lights turning on and off are the microlensing events, discovered in Gaia Data Release 3 G,BP and RP time-series.
Each event is seen as temporal brightening of a background star caused by the space-time curvature due to a foreground lensing object, either a star or some dark lens, for example a white dwarf, neutron star or even a black hole.
The timer in the corner shows the moment of time in years and the events are displayed with their real observed duration and background star colour, but the amplitude is not to scale.
There is 363 microlensing events catalogued in Gaia DR3. More details in Wyrzykowski et al. 2022.
