This position, about 1 million miles (1.5 million kilometers) away, will help to keep the telescope cool, which is vital in infrared astronomy (the Hubble, by comparison, is an optical telescope, so it doesn't face this requirement). Add to that the spacecraft's complex transition from its launch configuration, ...
“These acoustic oscillations ran for a few hundred thousand years in the very early universe,” says Mark Halpern, Professor of Physics and Astronomy at the University of British Columbia and a CHIME investigator. “They left spherical shells of about four hundred million light years in diameter, a size that we ...
“I didn't believe the ancient galaxy hypothesis initially, but finally I was surprised because it's not that common to find what you predict in astronomy,” Dr. Beasley said. “Typically, the Universe always comes up with more surprises that you can think about.” _____.

In July 1967, Jocelyn Bell Burnell noticed a “bit of scruff” in the radio data she was receiving at the Mullard Radio Astronomy Observatory. Together with her Ph.D. advisor Antony Hewish, she zeroed in and followed up on the strange signal. In February 1968, the pair (together with three additional ...
