Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered evidence that galaxy mergers matter. When two galaxies move close, gravity can ...

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

Whether or not galaxies merge depends on how strong the gravitational attraction is between the galaxies and whether the universe's expansion is more powerful than gravity. Gravity affects everything ...

(THE CONVERSATION) Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and ...
