New Structures found in the Milky Way - A Black Hole’s Eruption

NASA’s Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy.

“What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center,” said Doug Finkbeiner, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who first recognized the feature. “We don’t fully understand their nature or origin.”

The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old. A paper about the findings has been accepted for publication in The Astrophysical Journal.

Finkbeiner and his team discovered the bubbles by processing publicly available data from Fermi’s Large Area Telescope (LAT). The LAT is the most sensitive and highest-resolution gamma-ray detector ever launched. Gamma rays are the highest-energy form of light.

From end to end, the newly discovered gamma-ray bubbles extend 50,000 light-years, or roughly half of the Milky Way’s diameter, as shown in this illustration. Hints of the bubbles’ edges were first observed in X-rays (blue) by ROSAT, a Germany-led mission operating in the 1990s. The gamma rays mapped by Fermi (magenta) extend much farther from the galaxy’s plane.

Distracting the guard in order to escape.

Aside from Talas just generally being awesome, one thing I love about this scene is how it differs from similar scenes in other shows.

Usually (not always, but more often, I think) in TV shows, when characters make an escape plan like this, it seems to go along the lines of:

  • female character: Distracts the guard
  • male character: Beats up the guard
  • both: Escape

But in this scene it goes like this:

  • Talas: Distracts the guard and beats him up
  • Shran: Gets punched in the face. Does nothing useful whatsoever.
  • both: Escape

Furthermore, he seems quite satisfied for his girlfriend to take the leading role in this escape plan; he’s not surprised by her strength and her fighting skill and she doesn’t need to prove herself. It’s neither unusual for a female to lead an attack, nor is it a threat to his masculinity. There seems to be a complete equality here that is so normal to the characters that they don’t even note it or comment on it. This is one of the things I love about both Andorians, and Enterprise in general.

     Each bird in the Blackbird family of aircraft tells a different story. Some convoluted, some straight-forward. This SR-71A, #17967, on display at Barksdale Global Power Museum on Barksdale Air Force Base near Shreveport, Louisiana, first flew on August 3, 1966. She was deactivated, along with the rest of the fleet, in 1990.

     After a hiatus of the program, #17967 was one of three birds reactivated in 1995. In July of 1999, the Air Force transferred its four flying Blackbirds to NASA, for research operations out of Dryden Flight Research Center, now called Armstrong Flight Research Center, in honor of the recently late Neil A. Armstrong. 

     #17967 flew for NASA, performing experimental research flights, along with four remaining Blackbirds, until 1999, when those four aircraft were transferred to museums. Of that group, this bird was the first to retire, with a total of 2765.5 hours of flight time. But, she didn’t move to the museum immediately. Instead, she sat in a hangar at Dryden until 2003, while the museum raised money for transportation of the aircraft. She was the last Blackbird aircraft to be transported from her base to a museum, finally resting here on December 17, 2003. She wears the paint scheme that was current when the Air Force last flew the Blackbird aircraft.

     We’re offered a unique view inside the engine nacelle (shown in the second-to-last photo), as the engines have been removed. Before the Blackbird, nobody had ever built an aircraft out of titanium. It was too difficult to work with. The titanium struts, shown in that photograph, are a reminder of the Skunk Works team who meticulously milled the insanely tough material. The word, “tough” would be a good way to describe the materials used, pilots who dared to fly the bird, and the engineers who thought such an aircraft could be designed, and set out to make it happen.
