Summary

The Microwave Anisotropy Probe, a $95 million satellite scheduled for launch on 30 June, heralds a new era of sensing the remnant heat from the big bang. Its measurements should confirm--or refute--cosmologists' dearest models of the first incandescent moments of the universe. In this special focus on the cosmic microwave background, Science looks at current and upcoming experiments; a second story (p. 2236a) describes how theorists read the history and fate of the universe in the reverberations of the explosion that created it.
