Gravitational Lensing: What It Is And How It Is Helping Us Discover New Galaxies
Gravitational lensing occurs when a huge amount of matter, like a star, galaxy, or cluster of galaxies, creates a powerful gravitational field around it, strong enough to bend the light coming from distant galaxies (behind them). Roots...
