NASA's New Horizons deep-space probe has, for the first time, returned images to Earth that showed stellar parallax, or how the positions of stars shift when seen from two different places. This could ...
Over the 25 years I’ve written this column, I’ve often marveled at the mind-boggling distances to many celestial objects. Astronomers don’t often use miles to express stellar and galactic distances ...

A new method of measuring the distances between stars enables astronomers to climb the 'cosmic ladder' and understand the processes at work in the outer reaches of the galaxy. Astronomers from the ...
THE Observatory of Yale College has acquired a deservedly high reputation for the zeal with which the staff has prosecuted the inquiry into stellar parallax and the standard of accuracy consistently ...
