Gravitational microlensing is a transient but powerful phenomenon that occurs when a foreground mass – such as a star or a planetary system – temporarily magnifies the light from a more distant ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift alone through the Milky Way. Astronomers call these objects free-floating ...

brown dwarfs) ,or black holes of various sizes. Previous research shows that if some of the dark matter were in the form of MACHOs, then its presence could be detected by the gravitational influence ...

New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection experiments could function as highly precise gravitational wave detectors, thereby ...

Artist's impression of a microlensing event caused by a black hole observed from Earth toward the Large Magellanic Cloud. The light of a background star located in the LMC is bent by a putative ...

NASA’s Nancy Grace Roman Space Telescope will create enormous cosmic panoramas, helping us answer questions about the evolution of our universe. Astronomers also expect the mission to find thousands ...
