Stellar streams are star structures that are currently gaining a lot of popularity in the field of astrophysics. Streams are orbital in nature, and it is this particular property that makes them important dynamical tools in probing both the galaxy formation history of our galaxy and also the underlying dark matter distribution. During the presentation, an introduction on stellar stream structures would be provided, followed by the ways in which their geometrical and orbital structure are often exploited to understand, for example, the pre-merging history of our galaxy, the gravitational potential of the Milky way, and the dark matter distribution both at galactic and sub-galactic scales. I would also present some our new results, specifically a new panoramic sky map of the stellar streams of the Milky Way halo that we obtained from the prodigious ESA/Gaia DR2 dataset.
