What is gravitational lensing? | Cosmoknowledge

A cosmic magnifying glass: What is gravitational lensing? Gravitational lensing is a fascinating phenomenon in astrophysics, stemming from the bending of light by the gravitational field of massive objects. According to Einstein's theory of general relativity, mass and energy warp the fabric of spacetime, causing light to follow curved paths when it travels near massive celestial bodies such as galaxies, galaxy clusters, or even individual stars. When light from a distant source, such as a more

Up for an astronomy lesson? 🌌 Gravitational lensing is nature’s “magnifying glass,” and it allows us to see details from distant galaxies. But how does it work? Find out in this video ⬇️ | NASA's Hubble Space Telescope
