Gravitational lens, diagram
Gravitational lens. Diagram showing how light rays from distant stars are bent as they pass through the gravitational field of the Sun. This happens for light rays that pass close to the edge of the Sun, leading to a change (red line) in the apparent position of the stars near to the edge of the Sun or behind the Sun. This effect can be viewed during an eclipse, and measurements of this effect taken during an eclipse in 1919 helped lead to acceptance of Einsteins theory of General Relativity. The green grid, dimpled below the Sun and the Earth, represents space-time. In Einsteins theory, gravity is the warping of space-time by mass

EDITORS COMMENTS
This print showcases the phenomenon of gravitational lensing, beautifully illustrating how light rays from distant stars are bent as they pass through the powerful gravitational field of our Sun. The diagram depicts this bending effect, represented by the red line, which causes a change in the apparent position of stars located near or behind the Sun's edge. This intriguing optical illusion can be observed during an eclipse when measurements were taken back in 1919 that played a crucial role in confirming Einstein's groundbreaking theory of General Relativity. The green grid depicted below the Sun and Earth symbolizes space-time, as explained by Einstein's theory. In his revolutionary concept, gravity is understood as the warping of space-time caused by mass. This image serves to visually convey this complex idea with its artistic representation. The significance of this photograph lies not only in its aesthetic appeal but also in its scientific importance. It highlights key concepts such as astrophysics, focusing on celestial bodies within our solar system and beyond. Additionally, it emphasizes how gravitational lenses play a vital role in understanding fundamental principles like relativity and mass. This remarkable piece from Science Photo Library offers viewers a glimpse into both artistry and physics while commemorating significant milestones such as Eddington's famous experiment that validated Einstein's theories about gravity and light deflection along the line of sight.
