why neutron stars may be the coolest objects in the universe

Neutron stars’ thunder is usually stolen by black holes, but these bizarre objects living on the edge of physics create plenty of fascinating phenomena all on their own.

unmasking a monster: a “stunning confirmation” of black hole theory

The Event Horizon Telescope’s image of M87* is so good that theorists thought it was too good to be true.

are diffused galaxies a blow to the theory of modified gravity?

Are two galaxies which seem to lack dark matter proof that dark matter must be a particle rather than a quirk of gravity at cosmic scales. Well, it's actually kind of complicated...
