Quest for source of black hole dark matter
Like a game of "hide and seek," Lawrence Livermore astrophysicists know that there are black holes hiding in the Milky Way, just not where.

Using gravitational microlensing technique, an international group of astronomers has found a new substellar system whose composition remains a puzzle. The newly detected system, designated MOA-2015-BLG-337L, may consists ...
Using microlensing method, an international team of astronomers has detected a new "super-Earth" alien world circling a low-mass star about five times less massive than our sun. The finding is detailed in a paper published ...
Using microlensing technique, astronomers have found a new giant planet orbiting a brown dwarf located in the bulge of the Milky Way galaxy. The newly discovered exoplanet, designated OGLE-2017-BLG-1522Lb, is most likely ...
A University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing—an astronomical phenomenon and the only known method capable of discovering ...

The path of a light beam will be bent by the presence of mass, an effect explained by General Relativity, and a massive body can therefore act like a lens - a so called "gravitational lens" – to distort the image of an ...

(Phys.org)—As a result of NASA's Spitzer Space Telescope observations of a microlensing event, astronomers have found an extremely massive alien world circling a star located in the Milky Way's bulge. The newly discovered ...
Researchers are on the lookout for rapid, reliable and affordable switches for the opto-electronics of the future. An Empa team now presents a potential solution: dye droplets measuring just a few sub-micrometers in diameter.

Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending the distant starlight. Yet, in a 1936 article in the journal ...
