Discovery of a rare quadruple gravitational lens candidate with Pan-STARRS
Astronomers from the United States Naval Observatory (USNO) in conjunction with colleagues from the University of California, Davis, and Rutgers University have discovered the first quadruple gravitational lens candidate ...
Mapping dark matter
About eighty-five percent of the matter in the universe is in the form of dark matter, whose nature remains a mystery. The rest of the matter in the universe is of the kind found in atoms. Astronomers studying the evolution ...
Cosmic magnifying-glass effect captures universe's brightest galaxies
Boosted by natural magnifying lenses in space, NASA's Hubble Space Telescope has captured unique close-up views of the universe's brightest infrared galaxies, which are as much as 10,000 times more luminous than our Milky ...
Binary star composed of two brown dwarfs discovered by microlensing
Two new Saturn-mass exoplanets discovered
Astronomers discover new substellar companion using microlensing
Astronomers find unexpected, dust-obscured star formation in distant galaxy
Pushing the limits of the largest single-aperture millimeter telescope in the world, and coupling it with gravitational lensing, University of Massachusetts Amherst astronomer Alexandra Pope and colleagues report that they ...
Team puts dark matter on the map
A Yale-led team has produced one of the highest-resolution maps of dark matter ever created, offering a detailed case for the existence of cold dark matter—sluggish particles that comprise the bulk of matter in the universe.
One of the brightest distant galaxies known discovered
An international team led by researchers from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has discovered one of the brightest "non-active" galaxies in the early universe. Finding ...
