Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
A team of astronomers has developed a method that will allow them to "see" through the fog of the early universe and detect light from the first stars and galaxies.

(Phys.org)—A new study conducted by an international team of astronomers suggests that a recently discovered alien world, designated HD 131399 Ab, may not be a planet at all, but rather a background star. The researchers ...
Observations using ESO's Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations ...

(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source of very high-energy ...
