Neutron stars, the remnants of massive stars after a supernova explosion, have often been the focus of studies aimed at testing and unveiling exotic physics. This is because these stars are among the densest objects in the ...
Using the MIRI instrument onboard the James Webb Space Telescope, an international team of scientists made the first-ever detection of a mid-IR flare from Sagittarius A*, the supermassive massive black hole at the heart of ...

An international team of astronomers has conducted multiwavelength observations of a variable star designated Gaia22ayj. Results of the observation campaign indicate that this star is a magnetic accreting white dwarf. The ...
Collapsed dead stars, known as neutron stars, are a trillion times denser than lead, and their surface features are largely unknown. Nuclear theorists have explored mountain building mechanisms active on the moons and planets ...
