NASA | Swift Finds 'Missing' Active Galaxies
Most large galaxies contain a giant central black hole. In an active galaxy, matter falling toward the supermassive black hole powers high-energy emissions so intense that two classes of active galaxies, quasars and blazars, rank as the...

Galaxies, part 2
Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners, but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local...

NASA | NASA's Fermi Shows How Active Galaxies Can Be
Active galaxies called blazars make up the largest class of objects detected by Fermi's Large Area Telescope (LAT). Massive black holes in the hearts of these galaxies fire particle jets in our direction. Fermi team member Elizabeth Hays...

NASA’s Fermi Links Ghost Particle to Galaxy
Nearly 10 billion years ago, the black hole at the center of a distant galaxy produced a powerful outburst, and light from this blast began arriving at Earth in 2012. Astronomers using data from NASA's Fermi Gamma-ray Space Telescope and...

Quasars and Early Galaxy Formation
One type of object that some astronomers study is called a quasar. When these were first discovered, it was a bit confusing as to precisely what they are, which is why quasar stands for quasi-stellar object, since we thought they looked...

NASA's Fermi Links Cosmic Neutrino to Monster Black Hole
For the first time ever, scientists using NASA's Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at nearl-light speed before being detected...

NASA | Blazar Bonanza
A long time ago in a galaxy half the universe away, a flood of high-energy gamma rays began its journey to Earth. When they arrived in April, NASA's Fermi Gamma-ray Space Telescope caught the outburst, which helped two ground-based...

Was the Milky Way a Quasar?
The Milky Way galaxy is relatively calm by the destructive standards of the rest of the Universe, and compared to its own very violent past. But just recently we discovered that its violent past was much more recent than we thought - and...

Our Galaxy as a Frisbee - Size of the Visible Universe
The size of the universe may be impossible for anyone to truly comprehend, but that doesn't stop us from trying. We explore the size of the large scale universe by scaling our home galaxy, the Milky Way, to the size of a frisbee. How far...
