Most distant detection of water in the Universe

(PhysOrg.com) -- Astronomers have found the most distant signs of water in the Universe to date. Dr John McKean of the Netherlands Institute for Radio Astronomy (ASTRON) will be presenting the discovery at ...

Astronomical measurements must account for gravity

One of the consequences of general relativity is that light can be deflected by nearby masses. Mass curves space, and this curvature causes light to bend slightly. It was first observed during a total eclipse ...

Image: Magnifying the distant universe

(Phys.org) —Galaxy clusters are some of the most massive structures that can be found in the Universe—large groups of galaxies bound together by gravity. This image from the NASA/ESA Hubble Space Telescope ...

Image: Gravitational lensing in galaxy YGKOW G1

(Phys.org) —In this new Hubble image two objects are clearly visible, shining brightly. When they were first discovered in 1979, they were thought to be separate objects—however, astronomers soon realized ...

Distorting the lens

(PhysOrg.com) -- One of the most bizarre predictions of Einstein's Theory of General Relativity is the existence of back holes, objects that are so dense that not even light can escape from their gravitational ...

'Space warps' project needs your help

(Phys.org) —Astronomers are asking volunteers to help them search for "space warps." More commonly known as "gravitational lenses," these are rare systems with very massive galaxies or clusters of galaxies that bend light ...

Lensed galaxies

In 1915, Einstein amazed the world by predicting that the path of light could be bent by mass. As a consequence, light from a distant galaxy passing by an intervening galaxy en route to earth will be distorted. ...
