The first data collected by the Dark Energy Spectroscopy Instrument contain close to 2 million objects, including a roughly 12-billion-year-old quasar. The collaboration expects to report their first cosmology-related results within a year.

Marc Kamionkowski Johns Hopkins University theoretical physicist Marc Kamionkowski is one of three physicists to be awarded the 2021 Gruber Cosmology Prize for their contributions to methods essential for studying the early universe. The prize recognizes Kamionkowski’s discovery of a mathematical means to use radiation from the cosmic microwave background (CMB)-a relic of the earliest days of the universe-to glean information about what happened as far back as the first fraction of a second o...

Ideas, Inventions And Innovations New View of Nature’s Oldest Light Suggest Universe Is 13.77 Billion Years Old From an observatory high above Chile’s Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old – give or take 40 million years. A Cornell researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate...
