Galaxy mergers shed light on galactic evolution model

An Australian astronomer has solved a century-old mystery regarding how galaxies evolve from one type to another. The same study shows that the Milky Way, the galaxy we live in, was not always a spiral.

Chemical cartography reveals the Milky Way's spiral arms

Keith Hawkins, assistant professor of astronomy at The University of Texas at Austin, has used chemical cartography—also known as chemical mapping—to identify regions of the Milky Way's spiral arms that have previously ...

Tidal capture of an asteroid by a magnetar
