Ten years ago, astronomers made history when they first detected ripples in spacetime, called gravitational waves, from the ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding challenged deep-seated assumptions about how space behaves on the grandest scales ...

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 ...

Scientists are rethinking the universe’s deepest mysteries using numerical relativity, complex computer simulations of Einstein’s equations in extreme conditions. This method could help explore what ...

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 ...

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 ...
