Latest Einstein ring Stories
The molecular clouds that float about the universe hold the ingredients for star formation, say researchers at University of California, San Diego.
An astronomer has discovered a faint "satellite galaxy" that is the lowest-mass object ever detected 10 billion light years away.
Astronomers who survey galaxies in the distant universe are getting some unexpected help from gravity, according to a new study.
Cosmologists have come up with a new way to solve their problems -- they are inviting scientists, including those from totally unrelated fields, to participate in a grand competition.
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe.
Astronomers using NASA's Hubble Space Telescope have compiled a large catalog of gravitational lenses in the distant universe. The catalog contains 67 new gravitationally lensed galaxy images found around massive elliptical and lenticular-shaped galaxies.
NASA's Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern.
Employing a similar principle, a team led by Andrew Gould of Ohio State University will hunt for hard-to-see celestial objects, like black holes and dark matter, by observing how they affect light coming from stars behind them.
As Albert Einstein developed his theory of general relativity nearly a century ago, he proposed that the gravitational field from massive objects could dramatically warp space and deflect light.
Study will be published in June 30 New England Journal of Medicine.
Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...
