Zig-zagging across the universe
What’s better than a single gravitational lens? A double gravitational lens! Learn about how light from a distant quasar zig-zags across the universe because of the first double gravitational lens to be observed!

Gravitational lensing is a natural result and unique feature of Einstein’s theory of general relativity. It is also an important instrument in the cosmologist’s toolkit. Today’s paper highlights one way astronomers are using gravitational lensing to study dark matter.
Find out how astronomers have used the brightest known (to date) gravitationally lensed galaxy to learn about the early Universe.
The Hubble Tension is one of the great mysteries of modern cosmology…can today’s paper help us solve it?
Are your fairy lights being warped by a black hole this holiday season? Find out in today’s post!
What if we could use continuous gravitational waves from far away pulsars to learn about the inside of our very own sun? The authors of today’s paper explore what it would take to make this far-out idea a reality.
