Medicine & TechnologyImagine winning the Powerball jackpot-more than once. You may have a sense of how a team of astronomers feels after their discovery of a set of four quasars at the visible universe's edge. These brilliant beacons of light are typically spread far apart, but this quartet exists shoved together in only 650,000 light-years of space-equivalent to around a quarter of the distance between our closest big neighbor galaxy Andromeda and the Milky Way.
Every science fiction fan is familiar with the notion of parallel universes with the Star Trek series being one of the first to popularize the notion. However, thanks to the Large Hadron Collider, we may soon have proof that a parallel universe does, in fact, exist.
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.
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.
