Latest Strong gravitational lensing Stories
At the center of this image, captured by the NASA/ESA Hubble Space Telescope, two faint galaxies look like they realize they are being photographed and give a cheesy smile--like celebs on the red carpet.
Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before.
Measuring the invisible and intangible is a challenge for sure, but scientists have made inroads on one front: the study of dark matter and dark energy, two of the most mysterious substances in our cosmos.
In space, it sometimes happens that two galaxies are aligned in just the right way that the closer galaxy distorts and magnifies the appearance of the one behind it. For astronomers, finding these alignments is like coming across giant, cosmic magnifying glasses.
Yet another independent line of evidence points to the dominance of dark matter in galaxy clusters.
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.
A chance alignment of galaxies, recently observed by a space observatory, presents the perfect opportunity for studying star-forming galaxies billions of light-years away.
Astronomers have discovered the first known case of a distant galaxy being magnified by a quasar acting as a gravitational lens.
New work by a team led by a cosmologist from the U.S. Department of Energyâ€™s Lawrence Berkeley National Laboratory has made major progress in extending the use of gravitational lensing to the study of much older and smaller structures than was previously possible.
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...
