For the first time, astronomers have captured the brilliance of a superluminous supernova via gravitational lensing.

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...

The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU ...

Albert Einstein received the 1921 Nobel Prize in Physics for his contributions to theoretical physics and his discovery of ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

The speed of light has been one of science’s most trusted markers of stability. For more than a century, the idea that light moves through space at a constant speed has supported some of physics’ most ...

The findings, published in The Astrophysical Journal Letters, describe how detailed gravitational wave data from these mergers uncovered signs that at least one black hole in each event had already ...

The 1919 total solar eclipse provided the first empirical test of Albert Einstein's general theory of relativity, specifically measuring how the Sun distorts light from background stars. General ...

Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, mind-blowing, and totally changed how we understand energy and matter. Here’s how it ...
