Wright and his team used data on the locations of stars collected by the now-retired Gaia satellite to conduct a virtual census of more than 24,000 of the most luminous stars in the universe.

For example, the Sun has a magnitude of -26.7 which is, really, pretty luminous as most other objects outside our planet Earth. Comparing this, more distant stars might have magnitudes larger than ...

Sgr A*, in turn, is dwarfed by some supermassive black holes detected in other large galaxies such as one with a mass 6.5 billion times greater than that of the sun in a galaxy called Messier 87. That ...

The brighter the star is overall, the longer the period of luminosity. Since the cepheids in the Magellanic Clouds were all about the same distance from Earth, Leavitt concluded that the period ...
