Gravitational lens
Gravitational lens. Artwork showing how gravitational lenses can enable astronomers on Earth (upper right) to see magnified views (across bottom) of distant astronomical objects. Light (dotted lines) from these distant objects usually travels in a straight line, but can be deflected by very strong gravitational fields if they pass close to a massive star, black hole, or galaxy. This deflection can magnify the image, as illustrated across top. The bending of light by massive objects was predicted by Einstein in 1916 in his general theory of relativity

EDITORS COMMENTS
This artwork showcases the phenomenon of gravitational lensing, a concept predicted by Einstein in his general theory of relativity. The image depicts how astronomers on Earth can observe magnified views of distant astronomical objects through the use of gravitational lenses. In this illustration, we see dotted lines representing light from these far-off objects that would typically travel in a straight line. However, when they pass close to massive stars, black holes, or galaxies with strong gravitational fields, their path is deflected. This deflection results in a magnification of the image as shown across the top. The bottom part of the print displays examples of these magnified views obtained through gravitational lensing. It highlights how this technique acts as a cosmic telescope for observers on Earth, allowing them to study and analyze distant galaxies and nebulae with enhanced clarity. Through astrophysics and careful observation using this method, scientists gain valuable insights into our universe's vastness and complexity. Gravitational lensing serves as an invaluable tool for exploring celestial bodies that would otherwise remain hidden from our view. This stunning artwork not only captures the beauty and intricacy of space but also reminds us of humanity's continuous pursuit to unravel its mysteries using innovative scientific techniques like gravitational lensing.
