An Einstein Ring is a special case of gravitational lensing, caused by the exact alignment of the source, lens, and observer. This results in symmetry around the lens, causing a ring-like structure. [2] The geometry of a complete Einstein ring, as caused by a gravitational lens. The size of an Einstein ring is given by the Einstein radius.
The Einstein ring is formed by gravitational lensing, with the mass of galaxy NGC 6505 bending and magnifying the light from a more distant galaxy into a ring. NGC 6505 is a well-known galaxy only around 590 million light-years from Earth, and Euclid’s discovery of a spectacular Einstein ring here was unexpected. Read more
Strong gravitational lensing is a gravitational lensing effect that is strong enough to produce multiple images, arcs, or Einstein rings. Generally, for strong lensing to occur, the projected lens mass density must be greater than the critical density, that is . For point-like background sources, there will be multiple images; for extended ...
Einstein’s general theory of relativity predicts that light will bend around objects in space, so that they focus the light like a giant lens, with this effect being bigger for massive galaxies.
The European Space Agency (ESA) said Monday that its Euclid space telescope has detected a rare bright halo of light around a nearby galaxy.. Known as an Einstein ring, the halo was captured in ...
A new photograph from the Hubble Space Telescope shows a stunning “Einstein Ring” billions of light-years from Earth — a phenomenon named after Albert Einstein.
A light source passes behind a gravitational lens (invisible point mass placed in the center of the image). The aqua circle is the light source as it would be seen if there were no lens, while white spots are the multiple images of the source (see Einstein ring).
Wormholes in video games Game Description Space Rogue: The science fiction computer game Space Rogue featured the use of technologically harnessed wormholes called "Malir gates" as mechanisms for interstellar travel. Navigation through the space within wormholes was a part of gameplay and had its own perils.
