Berkeley, CA — Weak gravitational lensing is a uniquely promising way to learn how much dark matter there is in the Universe and how its distribution has evolved since the distant past. New work by a ...

The ring of light surrounding the centre of the galaxy NGC 6505, captured by ESA’s Euclid telescope, is a stunning example of an Einstein ring. NGC 6505 is acting as a gravitational lens, bending ...

In a groundbreaking discovery published in Monthly Notices of the Royal Astronomical Society, astronomers have identified a black hole within the Cosmic Horseshoe galaxy that challenges everything we ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Astronomers have reported a colossal find in a famous warped ring of light. Inside the galaxy that forms the Cosmic Horseshoe, researchers measured a black hole weighing 36 billion suns. The inner ...

Albert Einstein first recognized that a massive, dense object in the sky can act like a lens that can bend and focus light from behind it, known as gravitational lensing. Strong gravitational lenses ...

Everything we know—galaxies, stars, planets, our families, friends, and even pets—makes up just 5% of the universe. The remaining 95% is made up of mysterious components that scientists call dark ...

Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational ...

It’s one of the most memorable moments of my career – and not in a good way. I was giving a talk to a room packed full of eminent astrophysicists, but there had been a bit of a childcare crisis, so ...
