The discovery of dark energy by the first generation of high-redshift supernova surveys has generated enormous interest beyond cosmology and has dramatic implications for fundamental physics. Distance measurements using supernova explosions are the most direct probes of the expansion history of the Universe, making them extremely useful tools to study the cosmic fabric and the properties of gravity at the largest scales.

Dwarf galaxies provide opportunities for drawing inferences about the processes in the early universe by observing our Local Group and its vicinity. This issue is a snapshot of the current state of the art of dwarf-galaxy cosmology.

The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by dark energy. We review in detail the most well established methods for making such measurements.

The author reviews the current state of determinations of the Hubble constant, which gives the length scale of the Universe by relating the velocity of objects to their distance. Many object-based measurements give H0 values of around 72-74km/s/Mpc.

This text introduces some basic problems arising in gravitation and modern cosmology. All along the discussion the guiding theme is provided by the phenomenological and theoretical properties of the Cosmic Microwave Background (CMB).
