  • An outline of the possibilities and goals for the upcoming VLTI astrometry instrument GRAVITY.
  • A discussion on how we can use the strong appearance of ozone in the visible spectrum to hunt for exoplanets with Earth-like atmospheres.
  • An article looking at how the SINFONI Integral Field Spectroscopy Survey will help us to understand how galaxies form.
  • The results of the ESO Hidden Treasures astrophotography competition.
