As the great detective said, "When you have eliminated the impossible, whatever remains, however improbable, must be the ...

AI tools are transforming how we observe the world around us—and even the stars beyond. Recently, an international team ...

Leavitt discovered 2,400 variable stars, about half of the known total ... The brighter the star is overall, the longer the period of luminosity. Since the cepheids in the Magellanic Clouds ...

The third cross-check was done with Cepheid variable stars, which have a period–luminosity relation first discovered by Henrietta Swan Leavitt in 1908, which connects the period of pulsation ...

However you pronounce it, its unexpected dimming draws even more attention to this red supergiant variable star in Orion ... a lot of headlines as its luminosity has shifted dramatically several ...

Leavitt's work with variable stars led to her most important contribution to the field: the cepheid variable period-luminosity relationship. By intense observation of a certain class of variable ...
