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 ...

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

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

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 ...

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 ...

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.
