Have you ever wondered why hot objects glow? The answer lies in a fascinating phenomenon known as blackbody radiation. All ...

In what might come across as quantum wizardry, researchers at the University of Konstanz in Germany changed the properties of ...

But in the 1990s, chemists developed new types of persistent photoluminescent materials, such as strontium aluminate, that maintained a strong glow for hours after exposure to light.

According to a predicted phenomenon known as the Unruh effect, an accelerating object, such as a starship traveling at close to the speed of light, should generate showers of faintly glowing ...

For the first time ever, scientists have seen the light from behind a black hole. Black holes are regions in space-time where gravity’s pull is so powerful that not even light can escape its grasp.
