Latest Gravitational lensing Stories
An image of a galaxy cluster taken by the NASA/ESA Hubble Space Telescope gives a remarkable cross-section of the Universe, showing objects at different distances and stages in cosmic history.
Titan, Europa, Io and Phobos are just a few members of our solar system's pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun?
WASHINGTON, April 3, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has weighed the largest known galaxy cluster in the distant universe, catalogued as ACT-CL J0102-4915, and
Abell 2744, a giant galaxy cluster believed to have formed when four smaller galaxy clusters crashed into one another, is the subject of the first image captured by Hubble's Frontier Fields observational program, NASA and ESA announced Tuesday.
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 an ambitious new project, NASA officials are looking to combine three of the agency’s most powerful space telescopes in what is being called the deepest probe of the universe ever attempted.
Gravitational lensing is a technique used by astronomers that was first predicted by Albert Einstein's theory of relativity. Now astronomers have weighed one of the most distant galaxies in the universe using the specialized method.
Astronomers studying a new image of the massive galaxy cluster Abell 1689 have revealed the largest known population of globular clusters to date, NASA reported on Thursday.
The cluster CL0024+17, located in Pisces, is a galaxy cluster that is allowing astronomers to probe the distribution of dark matter in space. Dark matter does not reflect light and therefore cannot be seen. It is only detectable by the way its gravity affects the lights around it. Using gravitational lensing astronomers observe the distorted light around the dark matter and are able to tell where it is located within a cluster. A dark matter ring found near the cluster's center, by...
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...
