The "dark universe detective" space telescope Euclid has discovered its first Einstein ring in the process, learning about dark matter at the heart of a distant galaxy.

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Configurations like these, known as Einstein crosses, typically consist of four distinct points of light. This particular ...

In a landmark achievement, astronomers have noticed light bending in an unexpected manner, one that doesn’t align with the predictions made by Albert Einstein’s theory of general relativity. This ...

The birth, growth and future of our universe are eternally fascinating. In the last decades, telescopes have been able to observe the skies with unprecedented precision and sensitivity. Our research ...

About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein’s theory of general relativity. Published in 1915, and already widely accepted worldwide by ...

The universe rarely fails to amaze. One of its latest surprises—nicknamed the “Einstein zig-zag”—reveals a stunning arrangement of galaxies and a distant quasar. Together, they produce a gravitational ...

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 ...

Astronomers have uncovered what may be the most massive black hole ever found, 36 billion times the mass of our Sun, hidden at the heart of the Cosmic Horseshoe galaxy. Located 5 billion light-years ...

Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 ...

Rob Coyne receives funding from the National Aeronautics and Space Administration (NASA) and the US National Science Foundation (NSF). About a century ago, scientists were struggling to reconcile what ...
