  We summarize recent results presented in the astrophysics session during a
conference on ``Frontiers of Contemporary Physics''. We will discuss three main
fields (High-Energy Astrophysics, Relativistic Astrophysics, and Cosmology),
where Astrophysicists are pushing the limits of our knowledge of the physics of
the universe to new frontiers. Since the highlights of early 1997 were the
first detection of a redshift and the optical and X-ray afterglows of gamma-ray
bursts, as well as the first well-documented flares of TeV-Blazars across a
large fraction of the electromagnetic spectrum, we will concentrate on these
topics. Other topics covered are black holes and relativistic jets, high-energy
cosmic rays, Neutrino-Astronomy, extragalactic magnetic fields, and
cosmological models.
