This Hubble Space Telescope image features a remote galaxy, which appears as a red arc that partially encircles a foreground ...

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years from Earth (but appearing as it did around 11 billion years ago, when the ...

First predicted by Einstein, gravitational lensing occurs ... a look at the best cameras for astrophotography, and the best lenses for astrophotography.

In this scene, the nearer galaxy SDSS J020941.27+001558.4, is acting like a colossal magnifying glass in the sky. This allows ...

The celestial body that is causing the light to curve is called a gravitational lens, which should be able to help us detect the light from hidden galaxies. According to Albert Einstein’s ...

A distant galaxy, invisible for billions of years, has reappeared in a surprising form thanks to a rare cosmic illusion ...

Gravitational lenses are objects with significant enough gravitational fields that they bend light emanating from other sources in the universe. Gravitational lensing was proposed by Einstein as ...

In order to explain this, in 1905, Einstein suggested in Annalen der Physik that light comprises quantized packets of energy, which came to be called photons. It led to the theory of the dual ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over.

The James Webb «Space Telescope» took a picture of a gravitational lens with a very unusual shape that creates the effect of an Einstein ring. The European Space Agency (ESA) has named this lens the ...
