This feasting process is so intense that it creates a highly energetic object called a quasar – one of the brightest objects in the universe – as the spinning matter is sucked into the black hole’s belly. Now, researchers have found a galaxy that is surviving the black hole’s ravenous forces by continuing to birth new stars – about 100 Sun-sized stars a year. ![]() Illustration of the galaxy called CQ4479. The extremely active black hole at the galaxy’s center is consuming material so fast that the material is glowing as it spins into the black hole’s center, forming a luminous quasar. Quasars create intense energy that was thought to halt all star birth and drive a lethal blow to a galaxy’s growth.

NASA’s SOFIA Finds Galactic Puzzle, Black Hole or Newborn Stars?
Black holes are inherently strange, with gravitational forces so strong that nothing, not even light, can escape. As active black holes consume gas and dust, some of that material is instead launched outward as jets of high-energy particles and radiation. Usually these jets are perpendicular to the host galaxy, but NASA’s Stratospheric Observatory for Infrared Astronomy, or SOFIA, found one that is shooting directly into its galaxy. ![]() Artist’s concept of a jet from an active black hole that is perpendicular to the host galaxy (left) compared to a jet that is launching directly into the galaxy (right) illustrated over an image of a spiral galaxy from the Hubble Space Telescope. SOFIA found a strange black hole with jets that are irradiating the host galaxy, called HE 1353-1917. (ESA/Hubble&NASA and NASA/SOFIA/L.

NASA’s SOFIA flying observatory sees Atomic Oxygen in Atmosphere of MarsWritten by Kassandra Bell, SOFIA Science Center
Atomic oxygen affects how other gases escape Mars and therefore has a significant impact on the planet’s atmosphere. Scientists detected only about half the amount of oxygen expected, which may be due to variations in the Martian atmosphere. ![]() SOFIA/GREAT spectrum of oxygen [O I] superimposed on an image of Mars from the MAVEN mission. The amount of atomic oxygen computed from this SOFIA data is about half the amount expected. (SOFIA/GREAT spectrum: NASA/DLR/USRA/DSI/MPIfR/GREAT Consortium/ MPIfS/Rezac et al. 2015.

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) begins fourth year of studying objects in SpaceWritten by Nicholas A. Veronico
This operational period, known as “Cycle 4,” is a one-year-long observing period in which SOFIA is scheduled for 106 flights between now and the end of January 2017. ![]() NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) takes off from Palmdale, California at sunset. SOFIA is a partnership of NASA and the German Aerospace Center (DLR); NASA and DLR have collaborated on a range of activities and signed agreements on June 16 to work together to reduce aircraft noise and advance research into rotorcraft.

Tennessee Titans select outside linebacker Zach Brown in the 2nd Round of the NFL Draft
Brown led the Tar Heels last season with 105 tackles despite missing one game. He had 5.5 sacks, three interceptions and three forced fumbles his senior year. Brown has sprinter like speed recording a 4.5 second 40 yard dash at the combine. He is explosive off the line allowing him to shed blocks and get to the ball. «Read the rest of this article» Sections: Sports | No Comments
