Astronomers using NASA's Swift satellite recently detected a rise in high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, came from a previously unknown stellar-mass black hole.
An X-ray nova is a short-lived X-ray source that appears suddenly, reaches its emission peak in a few days and then fades out over a period of months. The outburst arises when a torrent of stored gas suddenly rushes toward one of the most compact objects known, either a neutron star or a black hole.
The rapidly brightening source triggered Swift's Burst Alert Telescope twice on the morning of Sept. 16, and once again the next day. Named Swift J1745-26 after the coordinates of its sky position, the nova is located a few degrees from the center of our galaxy toward the constellation Sagittarius. While astronomers do not know its
precise distance, they think the object resides about 20,000 to 30,00 0 light-years away in the galaxy's inner region.
Ground-based observatories detected infrared and radio emissions, but thick clouds of obscuring dust have prevented astronomers from catching Swift J1745-26 in visible light.

Question by Edward: How does a submarine produce electricity by running its "power lines into the water"? I saw this in the book World War Z, on page 247, where "Commander Song's father[...]came up with the idea of running floating power lines into the lagoon and leasing the electricity from our reactor." I'm sure this isn't esoteric and confined to this book. I'd just like to know how this cool process works. Thanks! Best answer for How does a submarine produce electricity by running its "power lines into the water"?:
Answer by Rick Answer by Mook
This is totally impractical. Submarines use generators to create their own power.
Read the sentence a bit more closely. "...leasing the electricity from our reactor." He's talking about selling the electricity generated by the sub's on-board nuclear reactor.
