Cepheid, a Danaher company and a leader in molecular diagnostics, today announced the publication of a study demonstrating the real-world impact of the Xpert Xpress MVP (multiplex vaginal panel) test ...

In 2011, Australian astrophysicist Professor Brian Schmidt co-won the Nobel Prize in physics for discovering that the ...

Cepheid variables are pulsating supergiant stars whose regular brightness variations are tightly correlated with their intrinsic luminosities. This period–luminosity relation, often termed the Leavitt ...

The Universe cannot be younger than the oldest stars it contains. If we can measure the age of the oldest stars in our Galaxy with high precision, then we can establish a reliable lower limit for the ...

Occasionally, the calendar aligns so that I get to complain about daylight saving time in this column on the same weekend it goes into effect. I need to take the chance to do that whenever I can. Just ...

Astronomers begin with a 300 million kilometer baseline — the diameter of Earth’s orbit — using parallax to measure stars up to 400 light years away. Beyond that, they rely on Cepheid variable stars ...

THE oscillations induced in the principal modes of vibration of a star by a free oscillation in one of them, generally of the second order in the corresponding free amplitude, are unimportant unless ...

Researchers have discovered that Cepheid variable stars in our neighboring galaxy, the Small Magellanic Cloud, are moving in opposing directions along two distinct axes. They found that stars closer ...
