For the first time, scientists have witnessed the cataclysmic crash of two ultra-dense neutron stars in a galaxy far away, and concluded that such impacts forged at least half the gold in the Universe.
Great excitement rippled through the physics world Monday at news of the first-ever detection of two ultra-dense neutron stars converging in a violent smashup.
As far as galaxies are concerned, size can be deceptive. Some of the largest galaxies in the Universe are dormant, while some dwarf galaxies, such as ESO 553-46 imaged here by the NASA/ESA Hubble Space Telescope, can produce ...
A powerful tool for characterizing and classifying gamma-ray bursts (GRBs) to allow their use as tracers of the expansion history of the universe has recently been presented by an international team of researchers. The work, ...
Quasars are galaxies with massive black holes at their cores. So much energy is being radiated from near the nucleus of a quasar that it is much brighter than the rest of the entire galaxy. Much of that radiation is at radio ...
The astrophysics world is abuzz after the first-ever observation of two neutron stars merging in a cataclysmic crash that left a rich trail of debris for scientists to comb through.
Thrilled physicists and astronomers announced Monday the first-ever observation of the merger of two neutron stars, one of the most spectacularly violent phenomena in the Universe.
For the first time, astronomers have observed in visible light a cataclysmic cosmic event that generated gravitational waves detected on Earth.
More than a month before a game-changing detection of a short gamma-ray burst - a finding announced today - scientists at Oregon State University predicted such a discovery would occur.
