Fifty experts on nuclear physics, particle physics and astrophysics met at CERN from 9 to 13 June to discuss how to use ...

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

The most luminous kilonova candidate to date (short gamma-ray burst 200522A) was detected using the Hubble Space Telescope, Swift Observatory and other telescopes. A kilonova is a "the afterglow ...

These are rare occurrences—scientists estimate that the giant black hole at the center of our Milky Way galaxy gobbles a star ...

The neutron star is a rare example of a ‘spider pulsar’ — one that consumes the material around a companion star, or causes it to scatter away by emitting powerful beams of radio waves.

Neutron stars are the leftover cores of exploded stars and the densest known material in the universe. A typical neutron star has a mass a few times the mass of the sun, compressed into a region ...

They further noted that the gamma rays produced would depend on the axions’ mass and only last 10 seconds after the neutron star forms. After that, the production rate would drop dramatically. This ...

The three exceptionally cool neutron stars identified are PSR J0205+6449, PSR B2334+61, and CXOU J0852−4617, located within the supernova remnants 3C 58, SNR G114.3+0.3, and SNR Vela Jr ...

A neutron star accreting material from a companion star, producing periodic X-ray bursts. Inset shows how the new data affect the temperature dependence of the synthesis flow of chemical elements ...

From 23 million light years away, the planet M51-ULS-1b is visible only as a roughly 3-hour drop in the X-ray radiation coming from the star M51-ULS-1. In archived Chandra observations dating back ...

Nothing inspires stellar awe quite like a neutron star. Often stretching only 15 miles across, these dead, collapsed stars can contain up to 2.5 times the mass of our own Sun (which is 865,000 ...
