For years, scientists have worked to chart the universe’s massive structure, aiming to test key models of cosmology. These efforts also help uncover how galaxies form and change over time. While most ...

For centuries, scientists have puzzled over globular clusters, the dense star systems that orbit galaxies without dark matter ...

Scientists have discovered a giant black hole that they believe may have been formed in the first few microseconds after the ...

New computer simulations suggest the first magnetic fields that emerged after the Big Bang were much weaker than expected — ...

Astronomers at Penn State have nicknamed the objects “universe breakers,” which may be unusual black hole atmospheres and could represent a missing link in the fast growth of supermassive black holes.

That cosmologists cannot agree on one of the most elementary facts about the universe is striking enough. But that uncertainty produces others, too: it makes it impossible to calculate an exact age ...
