Space Gravitational Lensing
Massive objects like galaxies bend spacetime so severely that light curves around them, acting like a cosmic magnifying glass. This gravitational lensing effect allows astronomers to observe distant objects that would otherwise be invisible. Einstein predicted this in 1915, and it was confirmed during a 1919 solar eclipse. Today, gravitational lensing helps discover exoplanets and map dark matter.
💡 Did you know?
Some gravitational lenses create multiple images of the same object, like seeing the same distant supernova explode multiple times from different paths!
