Non-luminous flames, however, are a different story. Because these have access to plenty of oxygen, they burn cleaner (read: no soot) ... For a flame (or any light source) to generate a shadow visible ...

self-luminous objects, like stars, which generate their own light, and non-luminous objects, that require an external energy source to be seen.

Luminous paints and tapes work by absorbing visible light during the day (or when interior light sources are switched on) and then releasing that light energy later.

Learn about how light is transmitted through different materials and how to create ray diagrams to show light transmission with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

These sources were chosen because they were close enough to Earth (all within 22 million light-years of the Milky Way) and bright enough to produce high-quality data.

Roughly 500 million light-years away, near the constellation Delphinus, two galaxies are colliding. Known as merging galaxy IIZw096, the luminous phenomenon is obscured by cosmic dust, but ...

A new approach to the design of light-emitting fabric could lead to the development of softer and more wearable luminous clothing, according to a project at the University of Windsor in Ontario.. The ...
