Observations suggest that nearly seventy per cent of the energy density in
the universe is unclustered and exerts negative pressure. Theoretical
understanding of this component (`dark energy'), which is driving an
accelerated expansion of the universe, is {\it the} problem in cosmology today.
I discuss this issue with special emphasis on the cosmological constant as the
possible choice for the dark energy. Several curious features of a universe
with a cosmological constant are described and some possible approaches to
understand the nature of the cosmological constant are discussed.
