The isotopic ratios measured in extragalactic gas clouds can be compared to Big Bang Nucleosynthesis calculations in order to place limits on the ratio of baryons to photons in the early universe. The new results come from the first year of a 3-year sky survey, which is the second phase of a project known as the Deep Extragalactic Evolution Probe.
