Henrietta Leavitt joined the Harvard College Observatory as a volunteer in 1895. She was appointed to the permanent staff in 1902, and eventually became chief of the photometry department. She worked ...
Using ESO's Very Large Telescope Interferometer (VLTI) at Cerro Paranal, Chile, and the CHARA Interferometer at Mount Wilson, California, a team of French and North American astronomers has discovered ...
Observing and studying our own galaxy, the Milky Way, can be a bit like trying to take in the view of an entire forest while standing inside it. But instead of trees obscuring the view, it’s gas and ...

Scientists have clocked the speed of Cepheid stars -- 'standard candles' that help us measure the size of the universe -- with unprecedented precision, offering exciting new insights about them.
Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...
New, vry precise measurements show that the rotation of the Milky Way is simpler than previously thought. A remarkable result from High Accuracy Radial Velocity Planet Searcher (HARPS), the most ...

“Classical Cepheids” are a type of pulsating star that rhythmically brightens and dims over time. These pulsations help astronomers measure vast distances across space, which makes Cepheids crucial ...
