A team of researchers from EPFL have found a way to use the phenomenon of strong gravitational lensing to determine with precision—about three times more precise than any other technique—the mass of a ...

Let's turn the sun into a telescope. In fact, we don't have to do any work—we just have to be in the right spot. But how can the sun be a telescope? The sun is not a mirror, but it is a lens. And we ...

When a gravitational lens magnifies a background galaxy, why don't we see the object doing the lensing, as we would if looking through an optical lens? Robert Hertrick Pittsburgh Gravitational lensing ...

A pair of Stanford University astrophysicists have proposed a new way to use gravitational lensing that would be up to 1,000 times more precise than current methods. The hope is to use the concept to ...

The Universe reveals hidden objects when gravity acts like a giant magnifying glass. Observatories at the cutting edge of technology — like the James Webb Space Telescope (JWST) — can harness these ...

Combining the way that massive galaxies and galaxy clusters bend space and magnify our view of the distant universe with powerful new instruments sensitive to gravitational waves and electromagnetic ...

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 ...
