Andromeda's Halo and Its Gaseous Glow

Thanks to the latest from the NASA Hubble Space Telescope astronomers may now be poised to understand the origins of our galaxy more clearly. A team of scientists led by astrophysicist Nicolas Lehner of the University of Notre Dame used the Hubble to find a massive gas halo surrounding the Andromeda Galaxy, our closest neighbor.

Eleven Galaxies on the Run

A team of Russian astronomers has announced the discovery of eleven galaxies that are on the run, after being pushed away from their original clusters, and are now floating adrift in what scientists describe as intercluster space.

Could Dark Matter and Black Holes Cause the Swirl In Your Galaxy?

Ever seen a snapshot of the universe and wondered just how and what makes the beautiful swirling shapes that modern telescopes now let us see? Imagery of the Horsehead Nebula, the Pillars of Creation, and even the Rose Galaxies have captivated researchers and the public for decades, but finding exactly what causes space dust, planets and stars to conform in such elegant forms has often eluded astronomers studying the infinite wonders of space. But a new study conducted by researchers with the Harvard University Smithsonian Center for Astrophysics (CfA) reveals that the connection between collections of stars and the elliptical shapes of galaxies may have something to do with dark matter and the presence of black holes at the center of every galactic mass.
