This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years ...

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

In 1987, an enormous blue arc, thought to be hundreds of trillions of miles long, was first considered one of the largest ...

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 ...

In what is the first discovery of an Einstein zig-zag lens in the universe, a team of international astronomers have sighted two galaxies which are aligned in a way where their gravity acts as a ...

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

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 ...

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 ...

C. Cuillandre, T. Li Einstein rings are gravitational lenses, or regions of spacetime in which gravitational fields bend and refocus light that passes through them. The light is magnified to an ...
