Pro Tip 1/3Scope of Comparison
Luminosity in astronomy usually involves comparisons with known brightness references like our Sun.
The luminosity of Sirius is almost twice that compared to our Sun.
Pro Tip 2/3Not Surface Brightness
Luminosity is the total light emitted, not just how bright a star appears on the surface.
Despite its size, the luminosity of Betelgeuse is due to its total energy output.
Pro Tip 3/3Measurement Complexity
Astronomical luminosity is complex, taking into account distance and inherent brightness.
Astronomers study a star's spectrum to accurately determine its luminosity.

And we systematically field tested, because in the field testing we learned some important lessons, and we went through many iterations. One of the key issues was battery consumption and charging. Luminosity was an issue, when you have too much bright sunlight outside. Often the roofs are broken, so you don't have enough

we can calculate their luminosity by measuring the period of this cycle, with more luminous stars changing more slowly. By comparing the light we observe from these stars to the intrinsic brightness we've calculated this way, we can tell how far away they are.

American Actor
I think of film when I paint. Even the luminosity that I always keep working for is really about film. But my idea is not to paint paintings that will decorate somebody's house.
Quote examples
Emily Maitlis
British Journalist
I am addicted to the highlighter pen, my papers generally a garish mix of type, Biro, unreadable scribble and lashings of luminosity, as if they belong to the unhinged.

Rekha
Indian Actress
A woman should be seen by the luminosity of her grace and not heard shooting her mouth away about praising herself which is so not lady-like.
