In May 2018, the star S2 made its closest approach to the galactic centre in 16 years. This star can help us study an elusive area of our galaxy, the heart of the Milky Way, which was not well understood until only a few decades ago. In the first of a series of three blog posts, Stefan Gillessen, astronomer with the galactic centre research group at the Max Planck Institute for Extraterrestrial Physics, shares more of what we previously knew of this area as the group releases the latest observations from this year.
