The SMITHSONIAN ASTROPHYSICAL OBSERVATORY is a part of the Smithsonian Institution which, in conjunction with the Harvard ...

Collision of Two Neutron Stars Billions of Years Ago Made Enough Gold and Uranium To Fill Earth's Oceans, Says Study Billions ...

New approach could aid “multimessenger” astronomy by quickly locating sources of gravitational waves emitted during these ...

A cosmic enigma, ASKAP J1839-0756, a slow-spinning neutron star discovered using the ASKAP radio telescope, is challenging ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorized. The study, led by the ...

A research team led by McGill identifies neutron stars as the likely source of fast radio bursts, one of the universe's most ...

Get Instant Summarized Text (Gist) Simulations indicate that the low-mass star in the J0453+1559 binary system could be a neutron star rather than a white dwarf. The star's mass, 1.174 M ⊙, is ...

Plutonium discovered at the bottom of the ocean was found to be refuse from a kilonova that exploded close to Earth 10 million years ago. Kilonovas occur when binary neutron stars spiral closer and ...

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. An interdisciplinary team of ...
