Seeing Quintuple: Hubble photographed Einstein's ring
Hubble's sensitivity and great resolution enable it to identify faint and distant gravitational lenses that ground-based telescopes are unable to detect. Hubble has took a stunning image of the Einstein Ring, which is billions of light-years away from Earth.The image depicts six brilliant light dots. They are forming a circle around a central pair with four of them. The seventh spot of light in the middle, according to Hubble data, is a rare fifth photograph of the distant quasar.
Appearances can be deceiving at times. There are just three galaxies in the formation, rather than six. It is actually made up of two galaxies and one distant quasar.In this view, the central pair of galaxies are two distinct galaxies. The four bright points surrounding them, as well as the fainter one in the centre, are five different photographs of 2M1310-1714, a single quasar. The quasar is further distant from Earth than the two galaxies.
Gravitational lensing is responsible for the Quintuple effect. Gravitational lensing happens when a big celestial body bends spacetime sufficiently to bend the path of light around it as if it were a lens.
