How Do Galaxies Die?

In a new study published in the journal Nature, researchers from the University of Cambridge and the Royal Observatory Edinburgh have found that when galaxies do die they die of strangulation.

Cause of Galactic Death: Strangulation

It's the ultimate whodunnit: what kills galaxies? A new study, published today in the journal Nature, names strangulation as the primary cause of galactic death.

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.

Ghosts of Quasars Past—Hubble Telescope Reveals Phantom of Eight Galaxies

In a new series of images captured by NASA’s Hubble Space Telescope, researchers with the US space agency discovered an eery green hue spiraling and braiding shapes around eight active galaxies. And while the wisps of glowing structures “don’t fit a single pattern”, lead researcher of the study, Bill Keel believes that the bright green lights may reveal the high energy at the core of these eight galaxies.

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.

Light Signals Discovered by NASA Reveal The Merging of Two Black Holes

For the first time ever, scientists have seen an unusual light signal that appears to be repeating itself from a distant quasar. And no, before the thought crosses your mind, this is not a sign of extraterrestrial life, but rather a signal from two black holes. These signals are an indication of two supermassive black holes that are in the last stages of merging together.

Eons After the Big Bang, and 80 Years After It Was Proposed, Dark Matter Takes Form in Andromeda

For decades now, researchers have long believed that the ever-elusive dark matter has comprised roughly 80 percent of the entire universe’s mass. But in spite of advancing technology, taking astronomers past the moon to far off comets/planets and back, researchers have not yet been able to identify the existence of dark matter in our galaxy or any other, and have not yet been able to isolate the hypothetical invisible particles in Earth labs either. But in what appears to be a strange X-ray emission from nearby galactic clusters, two independent European research teams believe that they may have found the first true dark matter known to man—and it’s not too far away either.

How the Milky Way Dominates the Stellar Block—Dwarf Galaxies, Get Out of the Way

It’s no big secret that humans tend to think of themselves as the center of the universe. It’s a flaw that has countlessly been proven wrong as science emerged and showed a different view of the world a around us. However, as it turns out, our galaxy may also be to blame for believing it too is the center of the universe.
