Description
14 years after the prize winning discovery of the accelerated expansion of the
Universe, the use of Supernovae Type Ia as cosmic standard candles still provide perhaps
the most direct probe of Dark Energy. I will review the present status of Supernova
cosmology as well as other cosmological probes. Then I will focus on what current
observations and survey can tell us about the properties of Dark Energy, i.e. our
(in-)ability to distinguish dark energy models from a cosmological constant. In the
last part I will give an outlook at what to expect from future surveys.
