The big bang didn't vanish… it's still here
The cosmic microwave background (CMB) is radiation that fills the universe almost uniformly—basically the leftover glow from ...
Bell Labs built a giant antenna in Holmdel, New Jersey, in 1960. It was part of a very early satellite transmission system called Echo. By collecting and amplifying weak radio signals bounced off ...
NEW ORLEANS — Astronomers using a NASA space telescope have discovered a region of the sky with a mysterious concentration of some of the universe's highest-energy radiation. The astronomers were ...
