Over billions of years, the universe has transformed from a simpler state into an intricate cosmic web, but new research ...

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.

T he Perseus cluster is enormous. It has a mass equivalent to 600 trillion Suns, and it looks like it has not stopped growing ...

Such a "lens effect" is also caused by gravitational fields: light moving through the universe is deflected, sometimes creating multiple images of the same object. This gravitational lensing effect ...

This effect can also reveal things about the lensing body, including its structure. And because dark matter has mass and ...

But perhaps the most beautiful effect of gravitational lensing is what's known as an Einstein Ring. This is where the distant galaxy is so perfectly centered behind the closer galaxy that its ...

Astronomers have confirmed a wandering black hole, about seven times the mass of the Sun, 5,000 light-years from Earth.

due to the powerful gravitational forces exerted by the lensing galaxy cluster. This creates the visual effect of the largest Einstein Cross ever observed. The discovery of such a large Einstein ...

Optical distortion due to gravitational lensing, a powerful effect determined by Einstein's theory of relativity, produces this photo. The role of gravitational lensing in forming an Einstein ring ...
