A black-hole system in a neighboring galaxy is twice as bright as astronomers had thought possible, a new study reports.
The incredible luminosity of the system in question, which resides about 22 million light-years from Earth in the Pinwheel Galaxy, may force a rethink of the theories that explain how some black holes radiate energy, researchers said.
"As if black holes weren’t extreme enough, this is a really extreme one that is shining as brightly as it possibly can," study co-author Joel Bregman of the University of Michigan said in a statement. "It’s figured out a way to be more luminous than we thought possible."
There’s a moment in Captain Phillips, Paul Greengrass’s excruciatingly tense tale of the 2009 capture of an American ship captain by Somalian pirate, where the audience gets a rare chance to laugh. It’s probably not meant to come off this way, but after 90-ish minutes of nightmarish, shaky-cam time spent with Tom Hanks’s schlubby title character and his harried, emaciated captors, the appearance of square-jawed, capital-H Handsome Navy Seals onscreen sent at least a few of the people in my theater into titters.
The mood changes in other ways once these guys literally parachute in and then, spoiler alert, bring an end to the hostage situation. An aircraft carrier and a couple Navy destroyers assist; as Time’s Michael Crowley wrote, “you feel that the U.S. military has come to your rescue.”
Captain Phillips joins a host of recent, acclaimed, non-fiction films that leave viewers gleeful about the power of the United States’ national-security forces. Zero Dark Thirty documented the abuses, dead-ends, and bureaucratic bullshit that prolonged the hunt for Osama bin Laden, but its final third satisfyingly drove home just how smart and surgical the CIA and Seal Team 6 ended up being. Argo leapt back a few decades to show Ben Affleck’s covert agent as a personality-free avatar of competence who whisked a group of stranded Americans out of a hostile Tehran.

A single bitcoin is now worth over $1,000, but the process of mining for the digital currency — in which people devote computing power to facilitate global Bitcoin transactions and secure the currency’s network — is growing increasingly expensive. Serious miners have started to build dedicated facilities for the sole purpose of Bitcoin mining. Journalist Xiaogang Cao visited one such center in Hong Kong, the “secret mining facility” of ASICMINER, reportedly located in a Kwai Chung industrial building.

"Around 2 AM among the many dead bodies inside the collapse, I found a couple at the back of the building, embracing each other in the rubble. The lower parts of their bodies were stuck under the concrete. A drop of blood from the man’s eye ran like a tear. Since then, this couple remains firmly in my heart. So many questions rose in my mind. What were they thinking at the last moment of their lives?"
