Rare Quasar Quartet is the First of Its Kind

Imagine 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.

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.

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.

Researchers Discover Dimming Switch on a Quasar

Scientists have long believed that at the center of quasars are massively powerful black holes. However, a new study from Yale University researchers indicates the exact opposite may be true. Researchers at Yale found that one particular quasar is actually dimming, and astronomers think it could be because of a black hole on a diet.

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.
