An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their ...
A pair of astrophysicists at the Rochester Institute of Technology has found via simulations that some black holes might be traveling through space at nearly one-tenth the speed of light. In their study, reported in Physical ...
In the early solar system, terrestrial planets like Mercury, Venus, Earth and Mars are thought to have formed from planetesimals, small early planets. These early planets grew over time, through collisions and mergers, to ...
