Description
The Optical Gravitational Lensing Experiment (OGLE) is currently the world's largest survey aimed at searching for variability in the sky. Currently, the project monitors brightness of about two billion objects in the densest stellar regions of the sky: central regions of the Galaxy, the Galactic disk, and the Magellanic Clouds. The OGLE Collection of Variable Stars currently contains nearly one million objects of various types and this is the largest set of variable stars ever obtained by any astronomical project. Recently, OGLE has greatly extended the list of known Cepheids in the Milky Way disk and used them to explore the structure, dynamics, and history of our Galaxy. I will present these results as well as other most spectacular latest OGLE discoveries in the field of variable stars.
