Do Comets Explain Mystery Star’s Bizarre Behavior?

The story of KIC 8462852 appears far from over.

The Milky Way’s New Neighbor May Tell Us Things About the Universe

As part of the Local Group, a collection of 54 galaxies and dwarf galaxies that measures 10 million light years in diameter, the Milky Way has no shortage of neighbors. However, refinements made in the field of astronomy in recent years are leading to the observation of neighbors that were previously unseen. This, in turn, […]
