Using the world’s largest, fully steerable radio telescope — the National Science Foundation’s Robert C. Byrd Green Bank Telescope (GBT) in W.Va. — an international team of researchers has given ...

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...

For all the impressive maps astronomers have made of the distant universe, much of the action has stayed out of sight. The brightest galaxies were relatively easy to chart. The faint hydrogen glow ...
