Latest Gravitational lensing Stories
In their quest to find solar systems analogous to ours, astronomers have determined how common our solar system is.
Astronomers have reason to believe that they have witnessed signs of the first planet to be spotted outside of our galaxy.
Variations in the brightness of the Q0957+561 quasar, also known as the â€œtwin quasarâ€ due to its duplicated image on Earth, are intrinsic to the entity itself and not caused by the gravitational effects of possible planets or stars from a far away galaxy.
Two independent groups have simultaneously made the first-ever ground-based detection of extrasolar planets thermal emissions.
Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope (VLT), astronomers have scrutinized the inner parts of the disc around a supermassive black hole 10 billion light-years away.
Three undergraduate students have discovered an extrasolar planet. The extraordinary find, which turned up during their research project, is about five times as massive as Jupiter.
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.
Abell 1689, shown in this composite image, is a massive cluster of galaxies located about 2.3 billion light years away that shows signs of merging activity.
An international team of astronomers has discovered an extra-solar planet of about three Earth masses orbiting a star with a mass so low that its core may not be large enough to maintain nuclear reactions.
A University of British Columbia astronomer with an international team has discovered the largest structures of dark matter ever seen. Measuring 270 million light-years across, these dark matter structures criss-cross the night sky, each spanning an area that is eight times larger than the full moon.
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...
