What do you get when you combine polarized radiation with Einstein's theory of general relativity? According to a group of astrophysicists at UC San Diego, you just might get more accurate estimates for the mass of ghostly subatomic particles known as neutrinos.

Based on observations from the South Pole Telescope, a team of international scientists has found subtle patterns in the cosmic microwave background called B-mode polarizations, according to a report in Physical Review Letters.

Non-Astronomy Scientists May Help Answer Cosmology Conundrum
2013-11-28 06:41:07

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.

Astronomers Use Gravitational Lensing To Weigh Most Distant Galaxy
2013-10-17 14:57:54

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.

Researchers at have discovered the first ever Type Ia supernova (SNIa), extraordinarily magnified by a gravitational lens.

Gravitational Lensing In The Unusual "Magatama" Galaxy
2013-04-01 09:37:32

In a course of studying young galaxies at a distance of 11.6 billion light years from Earth, a team of astronomers noticed a strangely shaped galaxy that looks like a "magatama", an ancient, comma-shaped Japanese amulet made of stone.

The Bullet Cluster is made up of two colliding clusters galaxies. According to a 2006 study, the Bullet Cluster also shows the best evidence for the existence of Dark Matter. From observations of galaxy cluster collisions it has been found that many show displacement between their center of visible matter and their gravitational potential. Each component, stars, gas, and dark matter, within a cluster pair behaves differently during a collision allowing for each to be studied separately....

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...
